Kenmore Refrigerator Error Code Icemaker Sensor

The Icemaker Sensor error means the refrigerator's control system has detected an abnormal reading from the icemaker temperature sensor. This fault is identified as a secondary error in display check mode, specifically shown by the Section B LED turning OFF. The sensor is responsible for monitoring the temperature of the icemaker assembly, and a failure in the sensor, its wiring, or the connection at CON8 on the main PCB will trigger this code.

The refrigerator's cooling system for food storage typically continues to operate during an icemaker sensor fault, so food safety is generally not immediately at risk. However, the icemaker itself may stop producing ice or operate unpredictably until the fault is resolved. It is best to address the error promptly to avoid any secondary issues with the icemaker assembly.

A reset may temporarily clear the error code from the display, but if the underlying problem with the sensor, wiring, or CON8 connection has not been corrected, the error will return. It is important to diagnose and repair the root cause before relying on a reset. Use display check mode after any repair to confirm the Section B LED behavior has returned to normal.

Start by checking the CON8 connector on the main PCB to make sure it is fully seated and free of corrosion or bent pins, as this is the most common cause of the error. If the connection is secure, test the icemaker temperature sensor for proper resistance values and inspect the wiring harness for damage. If the sensor has failed, it will need to be replaced. If both the sensor and wiring are in good condition, the main PCB may require evaluation.

If the issue is simply a loose connection at CON8, the repair may cost nothing beyond your time. Replacing an icemaker temperature sensor typically runs between $15 and $60 for the part, plus labor if a technician is performing the work. If the main PCB is the root cause, board replacement costs can range from $100 to $300 or more depending on the specific model.
