Ice maker continues to run even when the ice basket is clearly full; ice overflows.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Disconnected or failed ice-full sensor, Broken sensor bracket, Control PCB ignoring sensor input

Safety: Unplug the unit before inspection.

Steps:

1. Test sensor response: With the cover off and unit running, block the sensor beam path with your hand. The unit should stop making ice. If it does not, the sensor or PCB may be faulty.
2. Check wiring: Ensure the sensor harness is connected firmly to the main PCB.
3. Replace sensor: If wiring is intact but the sensor has no effect, replace the ice-full sensor board.
