Ice maker produces too much ice and does not stop even when bin is full.

Safety: Unplug the refrigerator before working on the ice maker.

• Clean sensor: For optical sensors, clean the emitter and receiver windows with a soft cloth. For mechanical arms, ensure they move freely.
• Check for obstruction: Make sure ice cubes are not wedged against the sensor or arm, preventing proper movement.
• Test function: Manually move the ice level arm (if present) and listen for a click. If no click or resistance, replace the ice maker.
• Replace sensor/ice maker: If cleaning and freeing movement does not restore proper shutoff, replace the ice maker assembly or sensor module.
