Possible Causes
Aged or drifting temperature sensor, Faulty thermostat (on mechanical models), Control board calibration error, Poor door seal causing heat loss
How to Fix / Troubleshooting
Safety first: Allow the oven to cool before inspecting seals or internal components.
- Use an oven thermometer: Place a reliable thermometer in the centre of the oven and compare actual temperature to the set value.
- Check door seal: Inspect the gasket for gaps or damage. Replace if it does not seal evenly all around.
- Adjust cooking: Temporarily adjust recipes by ±10–20°C based on your thermometer readings.
- Sensor/thermostat replacement: If the difference is large or unstable, have a technician replace the oven thermostat (mechanical) or temperature sensor (electronic models) and check control calibration.
