AGA oven overheats, burning food even at low settings.

Safety first: Turn off the power or gas supply before accessing internal components.

• Verify with oven thermometer: Place an accurate oven thermometer in the center of the cavity and compare the actual temperature to the set temperature.
• Check thermostat bulb (mechanical models): Ensure the sensing bulb is correctly clipped in place and not touching the oven wall or element.
• Inspect control knob: Confirm the knob is correctly aligned with the thermostat shaft and has not slipped.
• Sensor replacement (electronic models): If readings are consistently high, the temperature sensor probe may be faulty and should be replaced.

When to call a technician: Replacement and calibration of thermostats or control boards should be performed by an AGA-trained engineer.
