Possible Causes

Failed compressor, refrigerant leak, blocked capillary tube, non-functioning start relay or overload

How to Fix / Troubleshooting

Safety: Unplug the unit before removing rear panels. Sealed system work must be done by a certified technician.

User checks:

  • Listen for compressor: After turning the unit on, listen at the back. A healthy compressor will hum steadily. Clicking on and off may indicate a bad start relay or overload.
  • Check condenser fan: Ensure the condenser fan is running when the compressor should be on.
  • Feel condenser coil: After 5–10 minutes of operation, the condenser coil should be warm. If the compressor is running but the coil stays cool, refrigerant may be low or absent.
  • Inspect start components: With power disconnected, remove the compressor terminal cover and inspect the start relay and overload for burn marks or rattling (a sign of failure).

Next steps: Replace the start relay/overload if defective. If the compressor still does not start or runs but no cooling occurs, contact a refrigeration technician to diagnose the compressor and sealed system.
