Possible Causes
Failed main control board relay, open compressor start relay, defective compressor overload protector, disconnected compressor harness
How to Fix / Troubleshooting
Safety: Unplug the ice maker before accessing the compressor compartment.
Steps:
- Listen for operation: After pressing power, listen for the condenser fan and compressor. If both are silent, suspect control or relay issues.
- Check harness: Remove the rear panel and verify the compressor harness is firmly connected to the compressor, relay, and overload.
- Test relay/overload: With a multimeter, check continuity through the start relay and overload protector. Replace if open or heat-damaged.
- Control board output: If you are qualified, check for compressor voltage at the board output when the unit should be cooling. No output with correct input suggests a bad board.
- Replace board or relay: Replace the failed component with an Antarctic Star-compatible part and retest.
