Possible Causes
Disconnected compressor wiring, Failed compressor, Faulty main control PCB not sending power to compressor, Open thermal overload protector
How to Fix / Troubleshooting
Safety: Unplug the ice maker before testing electrical components.
Steps to diagnose:
- Check wiring: Remove the rear panel and verify that all wires to the compressor, start relay, and overload protector are firmly connected.
- Inspect overload: Check the thermal overload protector for signs of burning or deformation. Replace if suspect.
- Measure voltage (advanced): With extreme caution and only if qualified, measure voltage at the compressor terminals when the unit calls for cooling. No voltage suggests a control PCB fault.
- Replace parts: Replace a faulty overload protector or main control PCB as indicated by testing. A failed compressor requires professional service.
