Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the appliance. Work at the rear only when power is disconnected.
Step-by-step:
- Listen for sounds: After plugging in briefly, listen for clicking from the compressor area. Repeated clicks without running indicate a start issue.
- Inspect start device: Remove the rear lower cover and locate the start relay/PTC on the compressor. Check for burn marks or rattling pieces inside when shaken gently.
- Replace start device: If damaged, replace with a Liebherr-compatible start relay/overload assembly.
- Test: Restore power and observe if the compressor starts and cooling resumes.
Note: If the compressor still does not start or draws excessive current, the compressor itself may be faulty and requires professional replacement.
