The ice maker continues to run even when the ice bin is full, causing ice to overflow.

Safety First: Unplug the unit before working near the bin sensor.

Steps to Correct:

• Verify Bin Position: Ensure the ice bin is properly seated and not bypassing the sensor.
• Clean Sensor: For optical systems, clean emitter and receiver lenses. For mechanical levers, remove ice buildup.
• Test Switch: Use a multimeter to test the bin full switch for proper operation. Replace if stuck closed.
• Monitor Operation: After repair, run the unit and confirm it stops making ice when the bin is full.

When to Call a Technician: If the control board ignores a working sensor, board replacement may be needed.
