Possible Causes
Weak compressor start relay, Overload protector tripping, High head pressure due to dirty condenser, Failing compressor motor
How to Fix / Troubleshooting
Safety first: Unplug the freezer before working near the compressor.
- Clean condenser: Ensure the condenser coils and fan are clean and unobstructed to reduce compressor load.
- Check ambient temperature: Very high room temperatures can cause overload trips. Improve ventilation around the appliance.
- Inspect start device: Remove and examine the start relay/overload assembly. Replace if there are signs of overheating or if it rattles when shaken.
- Monitor behavior: After replacing the start device, observe if the compressor now runs continuously. If it still trips, the compressor may be failing internally.
