Ice maker indicates ice thickness sensor error; ice too thick or too thin

Safety: Unplug the unit before cleaning or adjusting sensors. Use gloves when working near sharp ice grid surfaces.

• Locate thickness sensor: On KitchenAid clear ice makers, the thickness sensor is usually a probe or electronic sensor near the evaporator plate or water curtain.
• Clean sensor: Remove mineral scale using ice machine cleaner and a soft brush. Rinse thoroughly.
• Check adjustment: If your model has an adjustable thickness probe, follow the service manual to set the correct gap or position.
• Inspect wiring: Ensure the sensor harness is intact and firmly connected to the control board.
• Replace sensor: If cleaning and adjustment do not correct ice thickness, replace the KitchenAid ice thickness sensor or probe.
