How to Fix / Troubleshooting
Safety first: Unplug the unit before working near sensors.
- Clean and inspect sensor: Wipe the ice full sensor lenses and ensure they are not covered by frost or mineral deposits.
- Check wiring: Verify the sensor harness is connected securely to the control board.
- Test sensor: With the cover off (if safe), block the sensor path with a non-reflective object and see if the unit responds by stopping ice production. If not, the sensor or board is faulty.
- Replace sensor or board: Install a new ice full sensor assembly first. If the issue persists, the main control board may need replacement.
