Kenmore ice maker shows E2 and stops the ice-making cycle; water may fill but ice does not harvest.

Safety First: Disconnect power before working inside the cabinet. Melted ice and water can create slip and shock hazards.

• Empty the ice bin: Remove all ice from the storage bin so you can access the bin sensor or thermistor.
• Locate the bin sensor: On many Kenmore undercounter ice makers, the bin sensor is either a thermistor mounted on the bin wall or an infrared emitter/receiver pair near the top of the bin opening.
• Check for obstruction and alignment: If your model uses infrared sensors, clean the lenses with a soft cloth and ensure nothing blocks the beam. Confirm the emitter and receiver are aligned and firmly mounted.
• Inspect wiring: Follow the sensor wires back to the control board. Look for pinched, broken, or corroded wires and reseat the connector at the board.
• Test the sensor: For a thermistor-style bin sensor, measure resistance at room temperature and compare to the tech sheet. For IR sensors, use the unit's diagnostic mode (if available) to verify bin sensor operation.
• Replace defective parts: If the sensor fails testing, install a new OEM bin thermistor or bin level sensor kit. Reassemble and restore power.
