How to Fix / Troubleshooting

Safety first: Unplug the unit before working near the ice full sensor or level arm.

Steps to stop overflow:

Clean sensor: Wipe the ice full sensor lenses or window to remove frost or debris.
Inspect level arm: If equipped, ensure the ice level arm is intact and moves freely. Replace if broken.
Check wiring: Verify that the sensor harness is connected securely to the control board.
Replace sensor: If the unit still does not stop when full, replace the ice full sensor assembly.
Control board: If a new sensor does not correct the issue, the main control board may be misinterpreting the signal and require replacement.

Ice maker overflows ice; continues making ice even when bin is full.
