Oven temperature too high; food burns even at normal settings.

Safety first: Isolate power before accessing internal components.

• 1. Verify with thermometer: Place an oven thermometer in the centre of the cavity and compare actual temperature to the set value over several cycles.
• 2. Check sensor mounting: Ensure the temperature sensor is firmly fixed and not touching the oven walls directly, which can cause false readings.
• 3. Inspect thermostat phial (mechanical): On models with a capillary thermostat, ensure the sensing bulb is correctly clipped in place and not kinked.
• 4. Replace faulty component: If the oven consistently overshoots by a large margin, replace the thermostat (mechanical) or NTC sensor (electronic). If the fault persists, the control board relay may be sticking and the board will need replacement.
