Ice maker runs continuously and does not stop even when the basket is full.

Safety first: Unplug the unit before inspecting sensors.

• Verify sensor cleanliness: Clean the ice full sensor windows near the bin with a soft cloth.
• Check mechanical arm (if equipped): Ensure the ice level arm moves freely and is not stuck in the empty position.
• Inspect sensor wiring: Access the sensor boards and confirm wiring is intact and connectors are secure.
• Replace sensor: If the sensor does not change state when the bin is full, replace the ice full sensor assembly.
• Control board: If a new sensor does not correct the issue, the control board may need replacement.
