How to Turn Off Your AGA Cooker in Preparation for Servicing

If you’re booking an AGA service in South Molton, Barnstaple, Braunton, Northam, or Winkleigh, one of the most helpful things you can do before your engineer arrives is turn off your AGA in advance. This allows the cooker to cool down fully and ensures a safe, thorough service.

Here’s everything you need to know about switching off your AGA before a scheduled maintenance visit — plus why regular servicing is a smart investment for your home.

Why Turn Off Your AGA Before a Service?

AGA cookers are designed to retain heat for long periods, but this makes them slow to cool down. If your cooker is still hot when the engineer arrives, they may be unable to complete important tasks like:

• Cleaning internal components

• Inspecting burner or heating elements

• Checking flue connections or thermostats

• Accessing electrical or oil feed systems safely

Turning it off 12–24 hours in advance helps your technician work safely and efficiently.

When Should I Turn Off My AGA?

Ideally, switch your AGA off the evening before your appointment to allow ample cooling time. In colder weather or for oil-fired AGAs, give at least 24 hours.

How to Turn Off Your AGA (Fuel Type Breakdown)

🔥 Oil-Fired AGA

1. Locate the oil control box or oil valve, usually on the side or beneath the unit.

2. Switch the valve to the 'off' position.

3. If your AGA uses electricity for ignition, turn off the power at the wall or breaker.

4. Wait 12–24 hours for full cooling.

🔥 Gas-Fired AGA

1. Find the main control knob or gas valve, often located behind the bottom door or under the appliance.

2. Turn the gas off at the source.

3. Also turn off any power supply for models with electric ignition.

Why Regular AGA Servicing Matters

Your AGA is more than just a cooker—it’s the warm heart of your kitchen. Whether it runs on oil or gas, keeping it in top working condition ensures safety, efficiency, and longevity. Here’s why an annual service is essential:
