Ice maker shows sensor error; unit may shut down or run erratically

Safety: Disconnect power before accessing sensors.

• Locate thermistors: KitchenAid ice makers typically have thermistors on the evaporator plate and in the bin or cabinet.
• Inspect mounting: Ensure each thermistor is firmly attached to its surface and not hanging loose.
• Check wiring: Look for pinched, cut, or corroded wires. Reseat connectors at both the thermistor and control board.
• Measure resistance: At room temperature, measure thermistor resistance and compare to the service chart. An open or 0 ohm reading indicates failure.
• Replace faulty thermistor: Install the correct OEM KitchenAid thermistor and route wiring away from sharp edges and hot components.
