Possible Causes
Defective compressor start relay, Open compressor winding, Failed overload protector, Weak mains voltage supply
How to Fix / Troubleshooting
Safety first: Unplug the unit. Work on compressor circuits only if you understand mains safety.
- Check mains voltage: Verify that the outlet provides the correct voltage with a multimeter.
- Inspect relay and overload: Remove the rear cover and check the start relay and overload protector on the compressor. Replace any components that show burn marks or rattling.
- Measure compressor windings: Test resistance between compressor terminals. If windings are open or shorted, the compressor must be replaced by a professional.
- PCB relay: If the compressor never receives power despite good start components, the main PCB relay may be faulty and require replacement.
