Regular maintenance keeps an AGA running efficiently and prevents costly problems later on. Whether your cooker runs on oil, gas or electric, a simple servicing routine will protect its performance and lifespan. Here is what to expect and when to schedule each step.
Why Regular Servicing Matters
An AGA is a heat storage cooker that operates continuously or for long periods. Components such as burners, thermostats and insulation are exposed to constant heat and need occasional adjustment or replacement. Routine servicing ensures:
- Safe and efficient combustion for fuel models
- Consistent oven temperatures
- Lower running costs
- Reduced wear on parts
- Early detection of potential issues
Recommended Service Intervals
The ideal service frequency depends on the fuel type:
Oil-Fired AGA
Service every 6 months.
Oil systems can produce carbon deposits that restrict the burner and flue. A six monthly clean keeps combustion efficient and helps prevent the cooker from going out unexpectedly.
Gas-Fired AGA
Service every 12 months.
Gas burners need less frequent cleaning, but annual checks are essential for safety and performance. Always use a Gas Safe registered engineer.
Electric AGA (Modern or Converted)
Service every 12 to 18 months.
Electric systems require minimal maintenance but benefit from regular checks to ensure elements, thermostats and insulation remain in good condition.
Seasonal Servicing Advice
Most people book their AGA service just before the cold weather arrives when they plan to turn the cooker back on for winter. This creates long waiting times, as many households are doing the same thing. Plan ahead and book your service well before autumn. Keep a yearly appointment in place so your AGA is ready when temperatures drop.
What Happens During a Service
A professional AGA service typically includes:
- Checking and cleaning the burner or heating elements
- Inspecting and adjusting thermostats and safety devices
- Cleaning and testing the flue or ventilation system
- Checking insulation condition
- Cleaning the oil or gas filters if applicable
- Verifying temperatures in all ovens and hotplates
- Inspecting door seals and hinges
If any worn parts are found they can be replaced before they cause performance issues.
DIY Maintenance Between Services
You can help keep your AGA in good condition by:
- Wiping surfaces regularly with a soft cloth
- Avoiding acidic cleaners that damage enamel
- Checking the oil level in the tank
- Keeping hotplate lids closed when not in use
- Watching for changes in temperature or noise that might suggest a problem
Signs Your AGA Needs Attention
- The cooker takes longer to heat up
- Oven temperatures are uneven or lower than usual
- Stronger fuel smell or visible smoke from the flue
- Unusual noises or clicking sounds
- Surfaces are hotter than normal to touch
If you notice any of these, it is time to book a service.
