E0Whirlpool Refrigerator — Whirlpool Refrigerator E0 Error Code

The E0 code indicates the ice maker's internal temperature sensor has failed or is reading outside its expected range. This sensor monitors the ice mold temperature to determine when the ice has frozen sufficiently to be harvested and when to allow the next fill cycle. Without an accurate reading, the ice maker may produce undersized cubes, stop cycling entirely, or fill at the wrong time and overflow. This code is distinct from ice maker mechanical failures — it specifically points to the sensor component.

Unplug the refrigerator and pull out the ice maker assembly (typically held by two top screws and one bottom screw). Inspect the small thermistor or sensor lead clipped into or near the ice mold. Test continuity and resistance with a multimeter. If the sensor is integrated into the ice maker module and not separately replaceable on your model, replacing the complete ice maker assembly (W11700250) is the most practical solution. Also check the wire harness connector to the ice maker for loose or corroded pins.
