Possible Causes
Failed ice level sensor, Disconnected sensor harness, Stuck mechanical bin switch, Control board not responding to level input
How to Fix / Troubleshooting
Safety first: Unplug the ice maker before working on sensors.
Resolution:
- Clean sensor: For optical sensors, clean the emitter and receiver windows. For mechanical switches, remove ice buildup around the actuator.
- Test sensor operation: Use a multimeter to check the sensor or switch changes state when the bin is full versus empty.
- Check wiring: Ensure the sensor harness is firmly connected to the main PCB and not damaged.
- Replace faulty parts: Replace the ice level sensor or bin switch if it does not operate correctly. If the board ignores a good sensor signal, replace the PCB.
