Possible Causes
Failed condenser fan motor, Obstruction in fan blades, Faulty fan wiring or connector, Defective fan output on main PCB
How to Fix / Troubleshooting
Safety: Unplug the unit before removing the rear panel.
- Access fan: Remove the rear lower panel to expose the condenser fan near the compressor.
- Check for obstructions: Clear any debris or insulation blocking the fan.
- Test motor: Spin the fan by hand; if stiff or seized, replace the motor. Measure resistance across the motor leads; an open circuit indicates failure.
- Check wiring: Inspect the harness and connector for damage. Repair as needed.
- Control output: If the motor is good but never receives power when the compressor runs, the main PCB may have a failed fan driver and should be replaced.
