Possible Causes
Failed outdoor fan motor, faulty fan capacitor (if used), seized fan bearings, defective outdoor PCB fan relay or triac
How to Fix / Troubleshooting
Safety: Turn off power immediately to prevent compressor damage.
Steps:
- Inspect fan: With power off, try to spin the fan blade by hand. If stiff or seized, the motor likely needs replacement.
- Check capacitor: On non-inverter units, inspect and test the fan capacitor; replace if bulged or out of spec.
- Wiring: Check fan motor wiring and connectors for burns or loose connections.
- PCB output: A technician should verify that the PCB is sending voltage to the fan motor when commanded.
Do not run the unit until the fan issue is corrected; overheating can destroy the compressor.
