If your AGA has been switched off over the summer, autumn is a good time to think about getting it ready for regular use again. Before switching your AGA back on for winter, check its condition, consider when it was last serviced and make sure you know which model and heating system you have.
There is no single restart procedure for every AGA. Oil, gas and electric models can operate differently, and some older cookers have been converted. Rather than giving instructions that may not apply to your cooker, here’s what to consider before you switch it back on.
What should you check before switching your AGA back on?
Start with a few straightforward observations while the cooker is cool and switched off. Look for obvious external damage, moisture or anything that has changed since it was last used. Think back to whether it was heating normally before the summer shutdown.
You don’t need to dismantle anything. Leave burner components, fuel connections, wiring and internal controls to a suitably qualified professional.
Why does your AGA model matter?
The correct way to restart an AGA depends on the fuel type, model and equipment fitted. Oil-fired models can have different burners, gas cookers have their own ignition arrangements and electric models use different controls. A cooker that has been converted may also work differently from its original specification.
Check the manufacturer’s or fitted system’s instructions for your exact cooker. If you cannot identify the model, see our guide to identifying your AGA model, or ask Smart Range before attempting to restart it.
What should oil AGA owners consider?
If you have an oil-fired AGA, consider when the burner was last serviced and whether the cooker was running reliably before it was switched off. If it had been going out, making unusual noises or struggling to reach temperature, mention this to the team before restarting.
Burner designs and relighting arrangements vary, so we don’t recommend following generic lighting instructions for an unfamiliar oil AGA. Smart Range can discuss your cooker and advise whether an inspection or service is appropriate.
What should gas AGA owners consider?
A gas-fired AGA should only be restarted in accordance with the instructions for its exact model. Do not adjust gas fittings or attempt to work on the burner yourself. If the cooker was unreliable before shutdown, ask an appropriately qualified engineer for advice.
If you suspect a gas leak, do not attempt to restart the cooker or wait for a routine service. In Great Britain, call the National Gas Emergency Service on 0800 111 999. Avoid flames and operating electrical switches, and leave the property if necessary.
What about electric AGAs?
Electric AGAs and converted cookers may have different settings, timers or controls. Use the instructions for the system actually fitted to your cooker, rather than assuming every electric AGA works the same way.
If you notice damaged electrical components, unusual noises or problems with heating, stop using the cooker and ask for professional advice.
Should you arrange an AGA service before winter?
If your AGA is overdue a service, has been unused for several months or showed signs of a problem before being switched off, it’s worth discussing AGA servicing with Smart Range before bringing it back into regular use.
Our team can discuss the model and symptoms with you. Where appropriate, an engineer can inspect the cooker, check its operation within the scope of a service and advise if further diagnosis or repairs are needed.
How long will an AGA take to warm up?
A traditional heat-storage AGA may take time to return to its normal cooking temperature after being off for the summer. The warm-up period varies by model and heating system, so allow for the guidance that applies to your particular cooker rather than assuming it will be ready immediately.
What if your AGA isn’t working properly after restarting?
If your cooker fails to start, repeatedly goes out or doesn’t reach its usual temperature, don’t assume there is one simple cause. Make a note of what happens, any warning indicators and when it was last serviced. Avoid repeated lighting attempts or adjustments to internal components.
The Smart Range team can discuss the symptoms and recommend the next step, including an AGA repair or inspection where needed.
Frequently asked questions
Do I need to service my AGA before switching it back on?
Not every summer shutdown automatically means a service is needed, but if servicing is overdue or the cooker had a problem before being switched off, it’s sensible to ask for advice.
Can I switch my AGA back on myself?
That depends on the model and its approved operating instructions. If you’re uncertain about the controls or relighting process, contact a specialist rather than guessing.
Why is my AGA taking a long time to heat up?
Warm-up time varies between cookers. If it takes longer than normal for your model or never reaches its usual cooking temperature, speak to Smart Range.
What should I do if my AGA won’t restart?
Note the symptoms and contact the team. Don’t dismantle the burner, adjust fuel connections or bypass safety controls.
