Possible Causes
Failed hood fan motor, defective fan speed relay on main control, faulty fan speed switch on user interface, loose wiring to fan motor
How to Fix / Troubleshooting
Safety: Unplug the microwave or switch off the breaker before servicing.
- Test speeds: With power on, test each fan speed from the control panel. Note which speeds work.
- Inspect wiring: With power off, access the fan motor and check wiring connections for looseness or damage.
- Motor vs. control: If the fan does not run on any speed, suspect the motor or its power supply. If only some speeds fail, suspect the control board or speed switch circuitry.
- Replace parts: Replace the hood fan motor if it does not run when powered. Replace the main control board if the motor is good but not receiving power on certain speeds.
