Q1. What power supply do I need to install my cooker?

Please ensure your fitters refer to the fitters guide before installation.

Ceramic and Induction models may be connected to a suitable 6mm cable with a 32-amp breaker (providing the isolator switch, which turns the power on and off to the cooker, does not incorporate a 13 amp socket). However to provide greater flexibility, we recommend a 10mm cable with a 45 amp breaker.


These are guidelines and other factors may alter the cable/breaker power. Therefore we cannot provide electrical information as the qualified electrician has to make calculations based on what is around the cooker e.g. boilers etc.

Q2. Where can I buy a Rayburn?

You can buy a Rayburn cooker from one of our Rayburn Heatcentres where our helpful specialists will be able to help you choose the perfect Rayburn for your home. We offer models that provide central heating, hot water and cooking, hot water and cooking or cooking only and our appliances are available for a selection of fuel types and in a range of beautiful colours. 

Q3. What's the difference between an AGA and a Rayburn?

The Rayburn, made by AGA in the same factory in Shropshire, shares many great features with AGA cookers, such as radiant heat cooking and a beautiful coating, but there are a few differences.

Rayburn cookers are available as cooking only, cooking and hot water or cooking, hot water and central heating models, to provide a solution for all your household needs in one appliance, whereas modern AGA appliances are designed to offer cooking only.

In addition, Rayburn cookers are available in more fuel types, such as oil, HVO, gas and electric. They also offer controls which operate the ovens more like a conventional cooker, unlike the pre-set temperature zones of the AGA.  

Q4. Where can I buy Rayburn spare parts?

For Rayburn cookers you can identify the relevant spare parts for your appliance here and you can purchase spare parts directly from the AGA Spares website.

You can also call 01952 643149 to order Rayburn spare parts. 

Q5. What fuel types are available for Rayburn cookers?

Fuel choice is becoming increasingly important so there are range of fuel options to choose from when you buy a Rayburn. Appliances are available in propane gas, natural gas, kerosene oil, HVO and electric fuels:

• Oil: 400 series, 600 series, 308K and Heatranger 60,80, 100 models 
• HVO (95% Hydrogenised Vegetable Oil) compatable models: Heatranger 60,80,100

Q6. Are Rayburn applicances HVO (Hydrogenised Vegetable Oil) compatible?

HVO (95% Hydrogenised Vegetable Oil) fuel is 100% renewable and is invaluable in helping the UK achieve its net zero carbon target, reducing up to 90% of net CO2 emissions. 

The Rayburn Heatranger has HVO compatible burners making the appliance eco-friendly, carbon-free and future-ready.  A conversion kit is necessary when operating on HVO which can be requested by the installer.  

Q7. Are Rayburn appliances carbon free?

The Rayburn Heatranger 60,80,100 has HVO (95% Hydrogenised Vegetable Oil) compatible burners making the appliance eco-friendly, carbon-free and future-ready. A conversion kit is necessary when operating on HVO which can be requested by the installer. 

Q8. How long does it take for the Rayburn Ranger to warm up?

• Roasting oven - Heats up from cold in 90 minutes, for high temperature cooking.
• 900W Grill - Heats up in 10 minutes from cold.
• Baking oven - Heats up from cold in 120 minutes, for moderate temperature baking.
•Cast-iron hotplate - Heats up to boiling mode from cold in 30 minutes. Heats up to simmering mode from cold in 20 minutes.

Q9. How often should a Rayburn be serviced?

Depending on the model of your Rayburn, servicing should be carried out once or twice a year by a fully trained Rayburn engineer.

Rayburn Ranger models do not require regular servicing.

Q10. How does a Rayburn work?

The Rayburn ovens, when hot, radiate heat to gently cook food, ensuring that it retains its moisture, goodness and nutrients. Rayburn Heatranger models feature a large cast-iron hotplate, with heat graduated along its length, making it easy to slide pans from boiling to simmering. The Rayburn Ranger also features a large round hotplate with boiling and simmering settings as well as a state-of-the-art induction hob.

Q11. How do you control a Rayburn?

Rayburn Heatranger models are controlled much like a conventional cooker, offering supreme flexibility and complete controllability for cooking, hot water and central heating. The main oven is thermostatically controlled so you can set the required temperature and the lower cast-iron oven is designed to operate at about half of the main oven temperature, giving you great flexibility in terms of temperature zones within your Rayburn Heatranger.

The Rayburn Ranger offers three ovens which are set to optimal temperatures for roasting, baking or simmering and warming. These ovens can be switched on and off independently, so you can control the energy you use and a flexible E-setting allows for lower temperature cooking in each cavity

Q12. Can I have a Rayburn that is for cooking only?

The all-electric Rayburn Ranger is designed to offer cooking only. 

Q13. Where are Rayburns made?

Every Rayburn is hand built at the AGA factory in Shropshire by our skilled craftsmen. It is then delivered to the home, ready assembled for ease of installation.

Q14. Can I cook without running the central heating?

Yes, all Rayburn central heating models are independently controllable so the boiler and ovens can be operated separately. 

Q15. Do I have to leave my Rayburn on all the time?

No, Rayburn cookers can be switched on and off as you need them. You can also keep your cooker on to provide background warmth if required.

The Rayburn Ranger offers a handy E-setting to provide some heat while using less energy.

Q16. Will the kitchen get too hot with a Rayburn?

It is easy to control the heat in your kitchen with a Rayburn appliance as you can switch it on and off as required, and you can change the temperatures of the Rayburn Heatranger ovens.

The Rayburn Ranger offers a handy E-setting to provide some heat while using less energy.

Factors such as kitchen size, house design and property insulation factors can also have an influence on heating levels.

Q17. How do I clean my Rayburn?

The cast-iron ovens are self-cleaning as spills and splashes, which naturally occur when cooking, are effectively burnt off and any carbon deposits left over can simply be brushed out with the AGA wire brush when the oven is cool. 

If you have a Rayburn with a vitreous enamel coating, it can be cleaned easily using the AGA Rayburn Enamel Cleaner and the stainless steel parts can be cleaned with the AGA Rayburn Stainless Steel and Chrome Cleaner.

We would suggest using hot water to clean the painted exterior of the Rayburn Ranger. This model also offers oven liners which can be removed and placed in the dishwasher. 

Q18. What happens in a power cut when a Rayburn is in use?

All Rayburn appliances are dependent on electricity for burner and system pumps operation and so will not operate in a power cut. They will need to be re-set once the power supply is reconnected. 

Q19. Do the burners make much noise?

In our experience Rayburn cookers with pressure jet burners operate at a level that is deemed as acceptable by our customers. Depending on which model you choose, pressure jet burners are audible, particularly when heating up, but the improvement in technology in the last few years means pressure jet burners are becoming ever quieter.

The Rayburn Ranger operates silently.

Q20. Is a Rayburn safe to use around children?

A Rayburn cooker is generally safer than most conventional cookers as there are no naked flames or very hot electric elements to touch and its controls are hidden.

Although the 'body' of a Rayburn is hot to touch, its surface temperatures is not sufficient to cause injury but will be felt and act as a natural warning, much in the same way that a conventional cooker will have hot oven doors.

Operational surfaces such as the hotplate and the interior of the ovens are obviously at a much higher temperature and care should be taken when children or vulnerable people are in the kitchen. 

Q21. What is the boiler efficiency of a Rayburn?

Rayburn offers a range of cast-iron models that also supply hot water and central heating and independent sources typically class these appliances in excess of 85% efficient. 

Rayburn central heating cookers are also fully programmable so they can be turned on and off to suit your needs. The flexibility to decide when and how to use your appliance will give you control over your fuel consumption and household heating bills.  

Q22. Can you get wood-burning AGA Stoves?

Yes, we offer a range of multi-fuel AGA Stoves that run on solid fuel (coal) and wood. 

Q23. How do I install a Rayburn Fire?

Our range of Rayburn Stratus electric fires are so easy to install. With no flue or chimney required and running on just a 13 amp supply means you can enjoy the warmth and look of a fire with no building work necessary. 

Delivered in one package, our range of Rayburn Stratus fire suites are simple to assemble. You can watch our helpful video here to learn more.

Q24. What is a Rayburn Fire?

Our collection of Rayburn Stratus Fire Suites and Electric Fires offer the ultimate flame picture combined with a controllable heat output. These electric fires do not require a flue or a chimney, just a 13-amp supply, and you can purchase a suite to best display your new fire in your home.

Q25. Where are AGA Stoves made?

AGA Stoves are made in the UK. 

Q26. How do I choose my AGA Stove?

We offer a fabulous range of AGA Stoves and Rayburn Fires to suit all homes and requirements, so you’re sure to find the perfect option for you.

First, you will need to consider the type of fuel you want your stove or fire to use. We offer stoves and fires that run on multi-fuel (coal and wood) gas or electric.  

Next, you will need to consider how your stove or fire will fit in to your home, would you prefer a freestanding or built-in model? Would you prefer a contemporary appearance or more traditional feel?

For more information take a look at our helpful Stoves Buyers’ Guide.

Q27. What heat output do I need?

The size of the stove you need is affected by a number a factors including the size of the room, the number and size of any windows in the room and the general level of insulation.

For an approximate required heat output, multiply the room width, height and length (in metres) together and multiply the result by 0.606. The result is an approximation of the kW required for the room. 

We would always advise that further guidance should be taken from your retailer who will be able to confirm the requirements and provide a home survey if necessary.

Q28. Do I need a chimney?

All multi-fuel stoves require a chimney and we advise that the chimney should always be fitted with an internal liner, in order to ensure that the flue system is sealed from the appliance to the point at which it exits the building. This is so that no leakage of combustion products can occur, as well as ensuring that the chimney has a good ‘draw’ in order to facilitate satisfactory combustion of the fuel and to achieve the best results possible from your chosen stove. This is especially important in older properties where the existing flue will in all probability have deteriorated in condition.

Our gas fired products are designed to work with a balanced flue pipework system which, as it offers greater flexibility on installation, may be an advantage if you do not have a suitable chimney for a solid fuel appliance.

Our electric appliances are ideal for any room as they do not require a chimney. Simply plug into a 13-amp socket and enjoy the ambience immediately

Q29. Do I need an engineer to install my AGA Stove?

Solid fuel appliances should be installed by a HETAS approved engineer. The installation of a solid fuel appliance is covered by building regulations and as such, upon completion of the work the installation has to be signed off and registered. Your HETAS approved installer can complete this paperwork as part of the commissioning process. This compulsory procedure ensures that the installation complies with building regulations, safety requirements and the manufacturer’s installation/operation instructions.

Installation of a gas stove must be carried out and commissioned by an engineer qualified under the Gas Safe registration scheme. This is a legal requirement for all gas work.

Electric stoves and fires require no specific installation, simply plug in and enjoy.

Your AGA Stoves retailer will be able to advise you on engineers who are qualified to install the stove of your choice.

Q30. What is meant by DEFRA exempt stoves and 2022 Eco Design Compliance?

If you live in a smoke control area then you will need to install a stove that has been tested to show that it will burn wood cleanly enough to pass the requirements of the Clean Air Act. These stoves are referred to as DEFRA exempt appliances.

A multi-fuel non-DEFRA approved stove may be installed in a smoke control area but you may only burn smokeless fuels (such as furnacite or anthracite etc) on these appliances. Domestic household coal is not allowable.

2022 saw the introduction of new emission standards which aim to reduce particulate emission and deliver an even cleaner burning performance. All new stoves must conform to this standard whereas stoves fitted prior to the introduction of this new standard will not be affected by this legislation.

All our models are approved for use in smoke control areas and are ECO Design Compliant with the 2022 standard.

Q31. What fuel can I burn?

AGA Stoves are multi-fuel appliances, capable of burning wood logs, smokeless fuels or peat briquettes.

The grate system on the stove ensures that the appliance will burn the fuel in the most efficient and effective manner.

Wood sold in volumes under 2m³, and manufactured solid fuels, must be certified as 'Ready to Burn'.  If you buy fuel accompanied by the 'Ready to Burn' logo, you can be confident that you are protecting yourself and your family from the effects of the most polluting fuels. Wood or log fuel used should not exceed a maximum moisture content of 20% as the use of wet wood will result in poor combustion, loss of efficiency, sooting of the stove window, combustion issues with the stove and excess sooting or tarring of the flue system.

Relatively inexpensive moisture meters are sold by a majority of stove retailers and are a worthwhile ancillary purchase, your retailer will be able to advise further.

The gas appliances are available for natural gas and for LPG (bottled gas – propane not butane). The appropriate fuel type must be identified at the point of purchase. LPG versions for properties without access to mains gas can be operated from either bottles external to the property or from a larger bulk tank.

Q32. What if I have a room sealed property?

To allow for installation of stoves in dwellings where external air vents are not permitted, known as ‘room sealed’ properties, many of our stoves can now be installed so that the combustion air can be supplied directly to the stove by means of an outside air connection at the rear of the stove.

Alternatively, you may be interested in an electric AGA Stove or Rayburn Fire which does not require a chimney or flue. 

Your local AGA Stoves retailer can advise on the models suitable for direct air connection.

Q33. What is the warranty on AGA Stoves and Rayburn Fires?

Multi-fuel and wood burning stoves carry a 1-year warranty for parts and labour and 5-years for parts only. This excludes some consumable items such as bottom bars and glass, which can be damaged by use of inappropriate fuels or misuse.

Our gas and electric products carry a 5 year warranty on the stove body and a 2 year warranty on the functional gas and electric components. Again, the first year covers parts and labour and from the second year, parts only.

All warranties are subject to the correct installation of the appliances and may be affected where the full installation requirements have not been complied with.

Q34. What if there is a small amount of smoke when I first use my stove?

After installing the stove, it is recommended that you run a couple of small fires initially to ‘season’ the stove. This will help to burn off the storage coatings on the stove before lighting a full fire .This coating is to prevent deterioration of the cast-iron during storage, prior to installation.

When operating the stove during this initial firing, it is recommended to keep the room well ventilated as an odour will be noticed in the short term, this is entirely normal and is not at all harmful.

Q35. What if I have soot depositing on the glass window of my stove?

The airwash system in the stove will enable the stove glass to remain clean when there is sufficient heat generated by the burning fuel. When soot deposits do form, this is typically a clear indication of poor combustion. 

Poor combustion can be caused by a variety of factors which may include some or all of the following:

• Poor quality damp fuel
• Poor chimney draught
• Lack of ventilation to the room in which the stove is fitted
• Burning the stove on a continual low fire setting

You can clean glass which has become sooted when the appliance is cold using a non-abrasive cloth and warm, soapy water. Purpose formulated glass-cleaning products for stoves may also be available from your AGA Stoves retailer.

If symptoms of sooting continue, we would recommend having your installer return to investigate, advise and take appropriate corrective action if required.

Q36. I've noticed 'webbing' or damage on the glass window of my stove

The ‘webbing’ appearance is consistent with sulphur deposits originating from the fuel and reacting with the glass. It is associated with the burning of solid fuel and is not reversible. If the glass is changed and the issue re-occurs then you will need to look at changing the fuel you burn and/or your fuel supplier.

Damage to glass is not a common occurrence and can be the result of the following:

  • Impact damage – for example, a piece of fuel sticking out from the firebox after re-fuelling.
  • Glass fixings are too tight, as the glass expands slightly on heating, if the glass has been replaced at some stage then it is possible that the retaining screws have been over-tightened which will not allow the glass to expand, thus causing it to crack. If replacing the glass the screws should be inserted until hand tight and then eased off by a quarter turn backwards.
Q37. What to do about dampness or moisture in the firebox?

This is due to condensation as the flue gases are cooling to the point where the gases turn to liquid. This can be caused by a number of factors which can include:

  • Poor or low flue draught – the chimney system to which the unit is connected does not allow for adequate air flow, so the fire in the unit cannot reach its optimal operating temperature.
  • Cold chimney – condensation develops on start up of the fire and until the necessary heat is transferred to the chimney system to establish the required draught, this condensation will remain in the firebox area.
  • Damp fuel – poor quality or damp fuel will affect the heat generated by the fire and the flue gasses from this damp fuel will be cooler.
Q38. Where can I buy AGA Stoves spare parts?

For AGA Stoves you can identify the relevant spare parts for your appliance here and you can purchase spare parts directly from the AGA Spares website

Gas appliances have to be maintained and worked on by a registered Gas Safe engineer and these products should not be regarded as DIY.

Q39. Does my stove need to be serviced?

There is little required by way of servicing a stove on a periodic basis. If your stove is a solid-fuel appliance, you will need to remove ash from the appliance and riddle the bottom grate. You would riddle far less with wood as wood is best burnt on a bed of ash with the combustion air coming from over the top of the wood rather that from beneath, which would be the case when burning solid fuel.

Every 12 months you should have your chimney swept to ensure that the flue way remains clear so as to facilitate good combustion of the fuel and stove performance.

Gas appliances should be checked by a Gas Safe registered engineer on an annual basis to ensure soundness of the gas supply and safe removal of combustion products. 

Q40. Can I leave the doors open when burning?

No, for safety and heat efficiency, we recommend that the doors are left closed when the stove is in use.

Q41. How does induction work?

Induction cooking is 90% efficient, fast, powerful, controllable and safe. Induction hobs work by heating the pan directly, rather than heating the hob, like ceramic and gas hobs.

The electricity within the induction hob generates a magnetic field and by placing a pan onto the induction zone you complete the circuit, so the pan becomes hot and in turn heats the contents of the pan.

Find out more about induction cooking here

Q42. What are the benefits of Induction cooking?

Induction is by far the most energy-efficient cooking method available by delivering over 80% of the energy it uses to the pan, this compares to 48% with gas.

Induction hobs are also safer to use as they only heat the cookware on the hob, the remainder of the surface stays cool and safe to touch. In addition, AGA induction hobs also offer advanced safety features such as a child lock functionality. 

Q43. What’s special about AGA cookers?

There’s no other household appliance that generates the emotion and loyalty of an AGA cooker. The AGA is an amazing cooker, it’s easy to use, a joy to live with and has been scientifically proven to cook food that tastes better, making it a great addition to any home. 

Q44. What’s special about cast-iron ovens?

AGA cookers feature cast-iron ovens that retain, evenly distribute and radiate gentle heat, preserving the moisture, flavour and goodness of food. Within the ovens, heat is radiated from all surfaces simultaneously to ensure a gentle cooking process without the fierce direct heat found in conventional cookers.

Q45. How do AGA cookers work?

The cast-iron heat storage ovens radiate heat from elements embedded in their surfaces to gently cook food, ensuring that it retains its moisture, goodness and nutrients.

Cast-iron AGA cookers feature ovens set to the perfect temperatures for roasting, baking and simmering and some models feature conventional ovens, hotplates for boiling and simmering and induction hobs.

The new generation AGA cookers are designed to remain on 24/7, however, they offer additional flexibility as ovens and hotplates can be operated individually. 

Q46. How do I cook on an AGA cooker?

Cooking on an AGA is so easy, although it may be a little different from what you are used to at first. All newer AGA cast-iron models feature a roasting oven, baking oven and simmering oven and hotplates which are set to the ideal temperatures for boiling and simmering. These dedicated cooking zones at pre-set temperatures offer ease and convenience when cooking.

If you’re new to AGA cooking, we would recommend taking a look at our cooking videos or booking yourself on to an AGA demonstration to learn how easy AGA cooking really is. 

Q47. Where are AGA cookers made?

We are very proud that each AGA and Rayburn cast-iron range cooker is built in our factory in Shropshire, England to the same exacting standards that have ensured the AGA cooker’s place as one of our most trusted and cherished British brands.

Q48. What is the smallest AGA cooker?

The AGA 60 is just 60cm wide and is perfect for kitchens limited by space. With cast-iron ovens for roasting/baking and simmering, and the choice of an AGA hotplate or gas hob, this cooker is everything you’d expect from AGA, all coated in a beautiful enamel finish. 

Q49. Does an AGA heat the house?

AGA cookers are no longer engineered to run central heating systems, however, they are designed to remain on all of the time and radiate useful background heat to help keep your kitchen feeling cosy. Many AGA models can be switched to an economy setting to keep gentle warmth in the room without wasting energy. 

If you’re looking for a range cooker that controls your central heating, a Rayburn by AGA may be the perfect appliance for you.

Q50. Are AGA cookers on all of the time?

AGA cookers can be left on 24/7, especially during those cold winter months, providing that useful background heat. These models are so flexible they allow individual heat storage ovens to be left on while others may be switched off to save energy. In addition, the AGA hotplates can be switched on and off as required, with fast heat-up times of 10-12 minutes, so they are ready to cook when you are. 

Q51. How much does it cost to run an AGA?

AGA running costs depend on the model of AGA that you have, the fuel type it uses and how you use your cooker.

The newer all-electric AGA models are much easier to control and provide the opportunity to lower running costs significantly thanks to economy settings, fast heat-up times for hotplates and the ability to operate ovens and hotplates individually.

Learn more about AGA running costs

Q52. How do I choose my AGA cooker?

We’ve designed an AGA for every cook and every kitchen, so we’re sure to have the perfect cooker for you. 

You can choose from our Everyday Radiant Heat collection, designed for those who desire more flexibility from their AGA, or our 24/7 Radiant Heat Collection designed more inline with the original AGA cooker.

You can take a look at our guide to choosing your cooker here and we have a range of test drive videos to help give you an idea of the features of each of the AGA collections.

Q53. What colours do AGA cookers come in?

Our AGA cast-iron cookers are coated with a beautiful vitreous enamel finish and you can choose from 16 gorgeous colours from contemporary neutrals, like Linen, Slate and Blush, coastal colours, like Salcombe Blue and Dartmouth Blue and our more traditional AGA colours such as Cream, Black and Pewter.

Choosing your AGA colour is a big decision, as your cooker will become the heart of your kitchen. For inspiration, take a look at our guide here.

You can order colour samples through an AGA shop if you want to see how certain shades will look in your home. 

Q54. Do I need special pans for induction cooking?

Yes, you will need induction friendly cookware for cooking on induction hobs. Pans need to be ferrous based, which means that a magnet should stick to the base, in order for the electric circuit to complete and switch on. 

Stainless steel or cast-iron cookware is ideal. You can find a selection of induction friendly cookware at AGA Cookshop.

Q55. Where can I buy AGA spare parts?

For AGA cast-iron cookers you can identify the relevant spare parts for your appliance here - and you can purchase spare parts directly from the AGA Spares website

Q56. What fuel does an AGA cooker run on?

Our new generation AGA models run solely on electricity as part of our commitment to creating more environmentally friendly and efficient models.

However, we still supply the AGA Dual Control, which runs on both electricity and gas. 

Q57. Everything you need to know about AIMS

AIMS is a program which allows you to adjust the temperature of your AGA R5 Series. We no longer manufacture AIMS models.

What power supply do I need to install my AIMS cooker?

Please ensure your fitters refer to the fitters guide before installation.

Ceramic and Induction models may be connected to a suitable 6mm cable with a 32-amp breaker (providing the isolator switch, which turns the power on and off to the cooker, does not incorporate a 13 amp socket). However to provide greater flexibility, we recommend a 10mm cable with a 45 amp breaker.

Note: These are guidelines and other factors may alter the cable/breaker power. Therefore we cannot provide electrical information as the qualified electrician has to make calculations based on what is around the cooker e.g. boilers etc.

Do I need to calculate the time for my AIMS cooker?

You do not need to calculate how long it will take for your cooker to switch on and warm up, your AIMS unit will do that for you. You only need to enter the time that the normal temperature is required. 

When do I need to move the temperature control knob?

You will only need to move the temperature control knob of your AIMS unit during the initial 48 hour learning period to ensure that the temperature reaches in to the black band on the handset. Following this, you will not need to move the control knob again, doing so may require AIMS to relearn. 

What happens to my AIMS unit in a power cut?

Power cuts for less than 15 minutes should have no affect on your AIMS unit as programs are safely stored in the AIMS unit inside the AGA and in the handset. 

If your AIMS unit is affected by a power cut, you can press the 'I' button to handshake or carry out a full re-establishment.

You should also bear in mind that the cooker needs electricity to operate and so if the power has been off for a long period of time, your AGA may require additional time to warm up before you can cook as normal. 

How do I carry out a full re-establishment on my gas AIMS AGA?

To carry out a full re-establishment on your gas AIMS AGA. switch the control knob on the AIMS unit inside the AGA back and fourth between manual and AIMS, until the blue neon light begins to flash. When this happens. press and hold the and buttons together on the handset until the blue neon light goes out completely, the handset display briefly says 'Serial Number', then release the buttons.

If the blue neon light does not completely switch off, but continues to flash with a faint output, then repeat the process stated above. 

When the connection has been made, language options will display on the screen and you will need to use the and buttons to scroll through the options, and use the button to confirm selection.

If the language settings have to be changed, the whole procedure will need to be repeated. 

Why do I need to leave the AGA on 'normal' for 48 hours before using AIMS for the first time?

When the AGA is commissioned, an engineer will set the temperature control knob to the approximate position to achieve the correct oven temperatures. You may need to slightly adjust the control knob to achieve the correct final temperature, which could take about 48 hours. The cooker can then be changed to AIMS.

AIMS will then learn how long it will take to reach your preset final temperature, which can take up to three days. 

Can I use AIMS for large dinner parties?

AIMS is intended to save energy when your AGA cooker is not in use and the principle of cooking on an AGA is based on the thermal mass of stored heat. If you are cooking a large meal, we would advise switching over to 'manual' the day before, in order to ensure that there is sufficient heat. 

Does AIMS affect the whole of the AGA cooker?

Yes, all cooking zones including ovens and hotplates are affected by AIMS. 

Can I use my AGA without my AIMS handset?

Yes, the control board will store the latest programmed time or you can simply switch the AGA to manual mode to operate the AGA on normal temperature.

Will my AIMS automatically update for daylight savings?

The AIMS unit is not real time and you will need to reset the time when the clocks change in spring and autumn. In addition, the handset will need to be re-programmed for a leap year. 

How will I know when the batteries are low on my AIMS handset?

The battery life is indicated on the handset - three dark pips represent a full battery. 

My AGA had AIMS added after it was installed - does this affect the guidance points?

No, but the original heat indicator might still be fitted to the front of the AGA and give a conflicting temperature with the handset display. In this situation, always go by the handset which offers a more accurate reading of stored heat. 

How do I override the program to use the AGA at normal heat?

If the AGA is on the 'low' mode between normal settings and you would like to use it at temperature, there are two things you could do.

1. Using your handset, press the thermometer button on the handset to switch on the boost function, which will override the current AIMS program and bring the cooker up to normal temperature. To switch off the boost function, simply press the thermometer button again.

2. Turn the control on the base unit to manual, remembering to later turn this back to AIMS.

Be aware that the AGA may take a number of hours to reach temperature depending on the programmed settings. 

How long does it take the AGA to go from low (200°C) to normal (240°C)?

The AIMS until has an inbuilt memory which assumes it will take three and a half hours to achieve normal temperature, for example, if you set the normal heat period to commence at 6pm, the appliance will begin to warm up at 2:30pm. This can take up to three cycles to perfect and the first couple of cycles may be early or late.

If different programmes are used on different days, it may take longer for the appliance to completely learn all the settings.

How do I know when the AGA is ready to use?

Once you have set AIMS, the heat indicator on the handset should show that the correct amount of stored heat is present. When you begin to cook, the indicator will show a drop in stored heat - this is normal and does not reflect the actual cooking temperature. 

It is advisable to have the AGA cooker up to temperature one hour before you need to use it so that it has a sufficient thermal store. 

Is my AGA cooker always in communication with my handset?

No, they only communicate every 15 minutes and only when they are in range. So, if the handset is brought out of a cupboard it may not communicate with the cooker immediately and may need some catch up time. This can be actioned immediately by pressing the back button. 

I want to use the AGA morning and evening - what is the best setting in between?

If the gap between the desired periods of use is longer than six hours use the low setting. If it is less than six hours, the AGA will not actually be able to reach the low setting, as it is so well insulated that it takes many hours for its stored heat to reduce. 

How quickly will the AGA cool down?

It can take many hours for the AGA to cool down due to the efficiency of the insulation. 

What happens if the batteries fail?

If the batteries run out simply replace the four AAA batteries in the handset.

In the meantime, you do not need to worry as the memory settings for the cooker are contained in the base unit. 

Q58. How quickly will the AGA cool down?

It can take many hours for the AGA to cool down due to the efficiency of the insulation. 

Q59. Can I take my AGA cooker with me when I move house?

The newer AGA models are much easier to move and can be taken with you when you move, however, we recommend that you do not try to move and transport your AGA cooker by yourself as they’re extremely heavy to manoeuvre and by doing so you could actually damage the internal components of the cooker. We would suggest contacting our customer services team who will be able to offer advice and talk you through the process.

If you have an older generation AGA cooker which has been sited within your kitchen, it may not be possible to move without disassembling. In these cases, moving may be extremely costly so it might be more worthwhile to leave the cooker behind and buy a new one when you move. 

Q60. How do I clean my AGA cooker?

The constant warmth of an AGA actually makes cleaning much easier, as the radiant heat carbonises any cooking spills and splashes. This means that the hot ovens and hotplates practically clean themselves, requiring only an occasional brush.

A daily wipe with a damp cloth should be enough to maintain the shine of your vitreous enamel surfaces. If spills are left, they can bake on and become more difficult to remove. In this case, we would recommend investing in AGA-approved cleaning products which are available from AGA Cookshop or at your local AGA shop

Q61. Can I have a module with my AGA cooker?

If you are buying an AGA Dual Control or 7 Series model you may choose to buy one with an additional integrated AGA Module to help fulfil the demands of your family life. The AGA Module features a conventional fan oven, a slow cook oven and a gas or ceramic hob, to offer additional cooking versatility.

You may also choose to purchase a freestanding AGA Module to use alongside your AGA cooker or for times when you don’t want to switch your AGA on. 

Q62. Can I change the fuel type of my AGA cooker?

Fuel conversions are not approved on any of the new generation AGA cookers. If you would like to upgrade to a new AGA cooker which uses a different fuel type, we would recommend contacting your local AGA shop, who will be able to advise on trade-in offers.

Q63. What do I do if I have a gas leak?

Immediately turn off the gas supply at the meter control valve or emergency control valve and extinguish any sources of ignition, for example cigarettes, and do not operate electrical light or power switches, either on or off. Ventilate the building by opening doors and windows. Ensure access can be made to premises. Call the gas service provider immediately on 0800 111 999.

Q64. How often does my AGA need to be serviced?

Recommended service intervals depend on the AGA model you own 

The newer AGA models, including the eR3, R3, eR7, R7 and electric AGA 60 do not require regular servicing. 

The electric Total Control and Dual Control AGA cookers require a service every five years, with an interim safety check recommended at two and a half years.

The dual fuel AGA 60 and AGA Dual Control cookers will need to be serviced every 12 months.

Traditional AGA R5 gas and electric cookers require a service every 12 months and oil AGA models every 6 months.


Q65. Can I air my washing on my AGA?

Yes, AGA heat-storage cookers radiate a gentle warmth that dries clothes beautifully, reducing your need for a tumble dryer.

Use an airer or clothes horse to dry your clothes, but be careful never to drape clothes or sheets in front of the ventilation holes on the burner door, electrical control panels or badge.

The AGA can also make light work of ironing items such as pillow covers or t-shirts. Simply place your item on the simmering plate cover overnight to be 'AGA-ironed'.

Q66. What should I do if steam comes through the doors when closed?

When the door of an AGA is closed steam should not be able to escape. This would indicate that the door is not sealed to the front of the AGA and may require adjustment. Please contact our customer services team to discuss this further.

Q67. I get a burst of steam when I open the AGA door, is this normal?

When the oven doors are open, steam will naturally flow out of the largest opening. This is normal and does not require further attention from an engineer.

Q68. Why do I get pools of water inside the ovens?

It is common for water to pool inside the ovens, even when you are cooking at a high temperature, due to high moisture content within the ovens when cooking food. To reduce pooling, we recommend using a lid on any cooking vessels to retain moisture or alternatively, wrapping food in foil.  

Q69. Why does water trickle down the AGA when cooking?

This should not be happening and could indicate an issue with the cooker or the way that it is being used. To reduce moisture within the ovens we recommend a lid is used on any cooking vessels to retain moisture or alternatively that food is wrapped in foil when cooking. If this is being done and the issue still occurs, please contact our customer services team.

Q70. Food burns and cooks unevenly in my AGA

Food can cook unevenly in the AGA ovens if they are not up to temperature, as the heat needs time to saturate the ovens so they are ready for full use. Check your product user guide and ensure that you are giving your cooker the recommended time to reach cooking temperature. 

When cooking on the base on an oven, ensure that the floor grid is used as this will prevent the base of the food from becoming over-cooked.

Also, certain ovens require a baffle plate to be fitted, to ensure the heat is evenly spread around the oven. If you are getting uneven cooking results, it may be because this has been removed or has moved out of place. 

If you are satisfied with all of the above but are still experiencing issues, our customer services team will be happy to discuss this further. 

Q71. What cookware should I use on my AGA?

AGA produce a wide range of cookware designed specifically for use on an AGA cooker. To get the most from your AGA, we recommend using specially designed AGA cookware, which features stackable lids, thick bases and detachable handles, to optimise space and cooking results. 

You can purchase AGA cookware from your local AGA store or from the AGA Cookshop website.

Q72. What is the best way to keep my AGA Fridge-Freezer clean?

To keep internal odours to a minimum it is best to periodically clean the inside shelves, crispers, bins and wall. 

For a bigger clean, first disconnect the appliance from the power supply and empty the appliance of food and remove the shelves. Clean the interior using warm water and bicarbonate of soda with a soft cloth. Dry the interior carefully with a suitable cloth.

Shelves and other accessories (plastic and glass parts) can be cleaned in the sink using dishwashing liquid and warm water. Make sure all soap is rinsed off and all parts are dry before replacing. 

DO NOT use harsh abrasives, or aggressive cleaners as these can damage the interior of the appliance.


Q73. What temperature should I keep my AGA Refrigerator?

The temperature of the fridge compartment should be between 0-8°C, so it will be sufficient to adjust the temperature setting of your refrigerator to 4°C.  Fresh foods become iced below 0°C, causing them to rot, whereas bacterial load increases above 8°C, and causes food to spoil. The freezer compartment should be set to a temperature between -18°C and -20°C for optimal performance. 

Q74. Where can I buy spare parts for AGA Refrigerators?
