Possible Causes

Failed exhaust fan motor, Faulty fan speed switch or relay on control board, Obstructed fan blades, Loose wiring to fan motor

How to Fix / Troubleshooting

Safety First: Unplug the microwave or turn off power at the breaker before servicing the fan.

  • Check fan settings: Verify that the fan is not set to Auto mode that only runs with certain conditions. Try all speed settings.
  • Inspect filters: Remove and clean or replace the grease filters. Clogged filters can strain the fan.
  • Access fan motor: Remove the top grille and, if necessary, the unit from the wall to access the exhaust fan assembly. Check for obstructions or debris in the fan blades.
  • Test motor: Use a multimeter to test the fan motor windings. Replace the motor if open or seized.
  • Control issues: If the motor is good but never receives power, the control board fan relay or fan switch may be defective and require replacement.
