Possible Causes

Weak compressor start relay, Overheating overload protector, High head pressure from dirty condenser, Failing compressor windings

How to Fix / Troubleshooting

Safety first: Unplug the unit and allow the compressor to cool before touching.

Steps:

  • Clean condenser: Ensure the condenser coil or grille is clean to reduce compressor load.
  • Inspect start device: Remove and inspect the start relay/overload assembly for burn marks or rattling components.
  • Replace start device: Install a new Cavin-compatible start relay/overload if the old one is suspect.

Professional diagnosis: If a new start device does not resolve the clicking and the compressor still fails to start, the compressor itself may be failing and will require a refrigeration technician to test and replace.
