Possible Causes
Weak or partially failed heating element, Faulty temperature sensor (NTC), Poor door seal causing heat loss, Miscalibrated thermostat or control board
How to Fix / Troubleshooting
Safety first: Turn off power before accessing internal components. Use heat-resistant gloves when working near recently used ovens.
Steps to check:
- Verify with oven thermometer: Place an oven-safe thermometer inside and compare actual temperature to the set temperature.
- Inspect door seal: Check the rubber gasket around the door for gaps, tears, or compression. Replace if not sealing properly.
- Element inspection: Look for cold spots or uneven glow on visible elements. Test elements for correct resistance and replace any that are significantly higher than specification.
- Sensor test: Measure the resistance of the temperature sensor at room temperature and compare with Montpellier specifications. Replace if out of range.
- Recalibration: Some models allow temperature calibration via the control panel; refer to the user manual to adjust if necessary.
