Possible Causes
Weak compressor start relay/PTC, low line voltage, failing compressor drawing high current, loose relay connection
How to Fix / Troubleshooting
Safety: Unplug the refrigerator before accessing the compressor area.
Steps to address clicking/chattering:
- Verify power quality: Avoid using extension cords or power strips. Plug directly into a properly grounded outlet.
- Access compressor compartment: Remove the rear lower cover and locate the start relay on the compressor.
- Inspect and test relay: Remove the relay and check for burn marks or rattling. Replace with an OEM Danby start device if suspect.
- Compressor evaluation: If a new relay does not resolve the noise and the compressor still fails to start, the compressor may be failing and should be evaluated by a refrigeration technician.
