Possible Causes

Refrigerant leak in sealed system, Failed compressor, Blocked capillary tube, Severely dirty condenser or non-operational condenser fan

How to Fix / Troubleshooting

Safety: Do not attempt to open the sealed system. Unplug the unit before cleaning or inspection.

Steps:

  • Check condenser and fan: Remove the rear cover and ensure the condenser fan motor runs and the condenser is clean. Clean dust and debris thoroughly.
  • Feel compressor: Carefully touch the compressor casing (after a few minutes of operation). It should be warm and vibrating slightly. Stone-cold and silent suggests it is not running; extremely hot may indicate a mechanical failure.
  • Observe evaporator: With the cover removed, check if the evaporator plate becomes cold and frosty within 10–15 minutes. No cooling suggests a sealed system issue.
  • Check for error codes: Some models may show E11 or similar when cooling is inadequate. Follow the corresponding steps.
  • Professional repair: If the compressor runs but there is no cooling, or if it fails to start despite a good starter and power, contact a refrigeration technician. Compressor or refrigerant repairs are not DIY tasks.
