Ice maker runs continuously without stopping even when the bin is full of ice.

Safety: Unplug the unit before working near sensors.

Steps to restore auto-stop:

• Clean sensor: Wipe the ice level sensor windows or mechanical flap to remove frost and debris.
• Check alignment: Ensure the sensor faces the correct area of the bin and is not bent away.
• Inspect wiring: Confirm the sensor harness is connected securely to the control board.
• Test with empty bin: Run the unit with an empty bin and observe whether it stops when you manually block the sensor (for optical types) or lift the flap (for mechanical types).
• Replace sensor: If the unit does not respond to sensor activation, replace the ice level sensor assembly.
