Possible Causes

Seized or failing compressor, Shorted compressor winding, Faulty compressor start relay or PTC, Blocked condenser causing high pressure and overload trip

How to Fix / Troubleshooting

Safety: Unplug the unit. The compressor and capacitor carry dangerous voltages; if you are not experienced, do not attempt live tests.

  • Ventilation check: Ensure the condenser coil and rear grille are clean and unobstructed. Clean dust with a soft brush and vacuum.
  • Listen for compressor: When powered (briefly), note if the compressor hums then clicks off (overload) or does nothing. Then unplug again.
  • Inspect start components: Access the compressor terminal cover and inspect the PTC starter/relay and overload protector for burn marks or loose connections.

Compressor electrical testing and replacement of start components should be done by a refrigeration technician. Do not attempt to open the sealed system or replace the compressor yourself.
