When your KitchenAid refrigerator displays the error code 4E, it signals a problem with the defrost sensor in the freezer compartment. This vital component is responsible for monitoring the temperature and ensuring proper defrosting cycles. The error suggests that the defrost sensor may be reading as either shorted or open, compromising its ability to function effectively.

Defective Defrost Sensor: The defrost sensor may be faulty, either reading as shorted or open. Wiring issues connecting the defrost sensor to the control board.
