Ice maker runs continuously and does not shut off even when the bin is full.

Safety: Disconnect power before working near the bin sensor.

• Free the sensor: Remove excess ice around the bin full sensor or mechanical arm. Ensure it moves freely.
• Clean optical sensors: For infrared sensors, clean the lenses with a soft cloth to remove frost or mineral film.
• Check alignment: Adjust the sensor bracket so the beam or arm correctly detects the ice level.
• Replace sensor: If the sensor does not change state when the bin is full or empty, replace the bin full sensor assembly.
