Possible Causes
Failed internal cooling fan motor, blocked cooling air passages, defective fan relay on control board, disconnected fan harness
How to Fix / Troubleshooting
Safety: Unplug the microwave and allow it to cool before servicing.
- Ventilation check: Ensure the upper cabinet and exterior venting are not blocked. Clean any grease filters and exterior vent flaps.
- Inspect cooling fan: Remove the outer cabinet and locate the internal cooling fan motor. Check that the fan blades spin freely and are not obstructed by insulation or debris.
- Harness and relay: Verify the fan motor harness is connected securely. If the fan never runs during cooking, the motor or control relay may be defective.
- Replace fan motor: If the fan is seized or noisy, replace the cooling fan motor assembly.
- Control board: If the fan motor tests good but never receives power, the main control board may need replacement.
