How to Fix / Troubleshooting
Safety warning: Disconnect power before accessing the compressor or control board. Refrigerant system work must be done by certified personnel.
- Check wiring: Inspect the harness from the main control PCB to the compressor start components for loose or burnt connectors.
- Test compressor windings: With the unit unplugged, remove the compressor terminal cover and measure resistance between terminals. Open or shorted windings indicate a failed compressor.
- Inspect PCB relay: Access the main control PCB and check the compressor relay for signs of burning or mechanical failure. If the relay is defective, replace the PCB.
- Professional compressor replacement: If the compressor is electrically or mechanically failed, contact a refrigeration technician to recover refrigerant, replace the compressor, and recharge the system.
