Possible Causes
Tripped or failed compressor overload protector, Overheated compressor due to poor ventilation, Locked compressor, Faulty wiring to overload device
How to Fix / Troubleshooting
Safety first: Unplug the freezer. The compressor and overload device can be very hot.
Steps:
- 1. Allow cooling: If the compressor is extremely hot to the touch, allow it to cool for at least 30–60 minutes with power disconnected.
- 2. Access overload device: Remove the compressor terminal cover. The overload protector is usually a small disc-shaped device connected to one of the terminals.
- 3. Test continuity: Disconnect the overload and test for continuity. An open reading at room temperature indicates a failed protector.
- 4. Check ventilation and condenser: Ensure condenser coils are clean and ventilation is adequate to prevent future overheating.
- 5. Replace overload: Install a new overload protector with the correct Miele rating. If the new overload trips again quickly, the compressor may be mechanically locked and require professional replacement.
