Possible Causes
Compressor not running, Failed compressor start relay, Main control board not sending power to compressor, Severe refrigerant leak or blocked capillary tube
How to Fix / Troubleshooting
Safety first: Unplug the freezer before removing rear covers. Do not attempt to open sealed copper lines.
Steps:
- Check basic power: Confirm the outlet works and the power cord is fully inserted. Verify the thermostat or control is not set to OFF.
- Listen for compressor: After plugging in, wait a few minutes. If the compressor is silent and not vibrating, remove the rear lower cover.
- Inspect start relay: Remove the compressor terminal cover and check the start relay/overload for burn marks or rattling. Replace if suspect.
- Check control board output (advanced): With appropriate safety and tools, verify that the main control board sends power to the compressor when cooling is demanded. If not, replace the board.
- If compressor runs but no cooling: The sealed system may have a leak or blockage. This requires a certified refrigeration technician.
