Possible Causes
Stuck cooling fan relay on the PCB, Shorted triac controlling the fan, Misreading temperature sensor causing the PCB to think the oven is hot, Wiring short between the fan and the live wire
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control area.
Steps to check:
- Verify that the oven cavity and top are cool; if still hot, allow more time for normal cool-down.
- Access the main control board and identify the cooling fan relay or triac (refer to the service diagram if available).
- Inspect for signs of relay overheating or solder bridges. A relay stuck in the closed position will keep the fan running.
- Check wiring from the PCB to the cooling fan for shorts to the live wire.
- If the relay is stuck or the triac is shorted, replace the main control board (component-level repair is not recommended for non-professional users).
Warning: Continuous fan operation is usually safe but indicates a fault that should be corrected to prevent further damage.
