Possible Causes
Failed fan motor, Obstructed fan blades, Faulty fan capacitor (AC motor types), Defective fan relay or driver on PCB
How to Fix / Troubleshooting
Safety: Unplug the unit. A non-running fan can cause compressor overheating.
Steps:
- Check for obstructions: Inspect and clear any debris from the fan area.
- Spin test: Manually spin the fan. If stiff, replace the fan motor.
- Capacitor check: For AC fan motors, test the fan capacitor with a capacitance meter and replace if out of tolerance.
- Electrical test: With appropriate safety precautions, verify that the fan is receiving voltage when it should be running. If not, the PCB driver or relay may be faulty and the board should be replaced.
