Possible Causes
Failed compressor start relay or PTC, Open compressor winding, Faulty overload protector, Defective main control board relay
How to Fix / Troubleshooting
Safety: Unplug the unit. Capacitors and compressor terminals can carry dangerous voltage.
Steps:
- Listen for clicks: When turning the unit on, listen for a click from the compressor relay. No click may indicate a control issue.
- Access compressor: Remove the rear or side panel to reach the compressor terminal cover. Carefully remove the cover.
- Check start components: Inspect the PTC start relay and overload protector for burn marks or cracks. Replace if damaged.
- Winding test: With a multimeter, test resistance between compressor terminals (C-R, C-S, R-S). Infinite or zero readings indicate a bad compressor.
- Control board: If compressor and start components test good, the main control board relay may not be energizing and may need replacement.
- Technician: Compressor replacement requires specialized tools and should be done by a licensed technician.
