Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the microwave before removing covers.
Ventilation checks:
- Ensure all external vents are clear of dust and obstructions.
- Clean any grease filters on combination models.
Fan inspection:
- Remove the outer cabinet to access the cooling fan motor (usually near the magnetron or top rear).
- Check that the fan blades are not obstructed and can spin freely.
- Test the fan motor for continuity and replace if open or seized.
- Inspect wiring from the control board to the fan.
If the fan motor is good but the fan never runs or runs constantly, the control board's fan driver circuit is likely faulty and the board will need replacement.
