Possible Causes
Weak compressor, Faulty start relay, Overload protector tripping, Low supply voltage
How to Fix / Troubleshooting
Safety first: Unplug the unit before touching the compressor or electrical components.
Steps to check:
- Verify voltage: Use a multimeter to confirm correct mains voltage at the outlet. Low voltage can cause repeated start attempts.
- Inspect start relay: Remove the relay and overload from the compressor terminals. Replace the relay if it rattles or shows burn marks.
- Allow cooling: If the compressor is very hot, let it cool for 30–60 minutes and try again. Persistent clicking after relay replacement suggests a failing compressor.
Compressor replacement and sealed system work must be done by a licensed refrigeration technician.
