Possible Causes
Faulty temperature sensor reading too low, stuck heating relay, failed control board temperature regulation, blocked cooling airflow around cavity
How to Fix / Troubleshooting
Safety first: Turn off the oven and disconnect power. Allow the oven to cool completely before inspection.
- Check sensor: Test the NTC temperature sensor resistance at room temperature and compare with specifications. Replace if out of range.
- Inspect relays: On the control PCB, check heater relays for welded contacts that may keep elements energized even when off. This is an advanced check and may require board replacement.
- Ventilation: Ensure that the oven installation allows proper airflow and that the cooling fan operates. Clean any dust or grease from vents.
- Test at lower temperature: After checks, run the oven at a moderate temperature and monitor. If F2 recurs quickly, the control board may be misreading temperature and should be replaced.
