GE Ventilation Fan Failure

Microwave over-the-range vent fan does not run or runs only on one speed when commanded.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed vent fan motor, Faulty fan speed relay on control board, Obstructed fan blades, Defective fan speed selector switch (on some models)

Safety: Unplug the microwave before servicing the vent fan.

Check settings: Verify the fan is not in automatic mode waiting for cooktop heat. Try all speed settings.
Clean filters: Remove and clean grease filters. Replace charcoal filters if clogged.
Listen for motor: If you hear a hum but the fan does not spin, the motor may be seized or obstructed.
Inspect fan (advanced): Access the fan assembly from the top or rear. Clear any obstructions and test the motor. Replace the vent fan motor if it does not run with proper voltage.
