Possible Causes
Failed compressor start relay or PTC, Open thermal overload protector, Faulty main control PCB not sending start signal, Open compressor winding
How to Fix / Troubleshooting
Safety first: Unplug the freezer. Only qualified persons should perform live voltage tests.
- Listen for sounds: Plug in briefly and listen. A repeated clicking from the compressor area suggests start device failure.
- Inspect start components: Remove the compressor terminal cover and examine the PTC relay and overload for burn marks or rattling pieces. Replace as a kit if damaged.
- Check compressor windings: With power off, measure resistance between compressor terminals and to ground. Replace the compressor only via a certified technician if windings are open or shorted.
- Control output: If the compressor and start parts are good, verify that the main control PCB is sending power to the compressor circuit when cooling is demanded. Replace the board if no output is present.
