Kenmore Refrigerator Error Code Icemaker Sensor

The Icemaker Sensor error on a Kenmore refrigerator indicates an abnormal condition detected in the icemaker temperature sensor circuit. This sensor monitors the thermal state of the icemaker assembly to ensure ice production occurs within the correct temperature parameters. When the control system detects that the sensor is reading outside its expected range, whether due to an open circuit, short circuit, or out-of-range resistance value, it flags this fault code. In display check mode, this secondary error is specifically identified by the Section B LED turning OFF, which helps technicians distinguish it from other sensor faults during diagnostics.

The icemaker temperature sensor is connected to the main PCB through connector CON8. This connection point is the first place to inspect because vibration, thermal cycling, and general wear can cause connector pins to loosen or corrode over time, interrupting the signal between the sensor and the control board. A loose or intermittent connection at CON8 can produce the same electrical signature as a failed sensor, making it critical to rule out a wiring issue before condemning the sensor itself.

If the CON8 connection is secure and the error persists, the sensor itself may have failed. Temperature sensors in refrigerator icemaker assemblies are typically negative temperature coefficient thermistors, meaning their resistance decreases as temperature rises. A sensor that reads open, shorted, or outside the expected resistance range for the current icemaker compartment temperature indicates internal sensor failure. In some cases, the main PCB may also be at fault if it cannot correctly process a signal from an otherwise functional sensor.
