Possible Causes
Failed fan motor, Disconnected fan wiring, Obstruction preventing fan rotation, Faulty fan driver on main control PCB
How to Fix / Troubleshooting
Safety: Unplug and cool the unit. Do not operate without a working fan; fire risk.
- Confirm symptom:
- Start a short cycle and listen; if you hear no airflow, stop and unplug.
- Check for obstructions:
- Look through the fan guard for stuck food or foil; remove carefully.
- Internal inspection (advanced):
- Remove the cover to access the fan.
- Try spinning the fan by hand; if stiff, the motor is likely failed.
- Check the motor wiring connector at the PCB.
- Replace parts: Replace the convection fan motor if it does not run with proper power. If the motor is good but not receiving voltage, replace the main control PCB.
