Kenmore Refrigerator Error Code Room Temp Sensor

This error means the refrigerator's control board has detected an abnormal signal from the room temperature sensor, which monitors the ambient air temperature around the unit. The fault is classified as a secondary error and is identified in display check mode by the Section A LED turning OFF. The most likely causes are a loose connection at the CON5 connector, a failed sensor, or damaged wiring.

The refrigerator may continue to run with this error active, but the control board cannot properly adjust operation based on ambient conditions without a functioning room temperature sensor. This could affect efficiency and compressor cycling over time. It is best to diagnose and resolve the fault promptly rather than running the unit indefinitely in this condition.

A power reset may temporarily clear the error code, but the fault will return if the underlying issue with the sensor, connector, or wiring has not been resolved. Clearing the code without fixing the root cause does not restore normal sensor operation. A proper repair of the CON5 connection or sensor is required to permanently resolve the error.

Start by locating and inspecting the CON5 wiring harness connector, as a loose connection there is the most common cause. Reseat the connector firmly and check for any corroded or damaged pins. If the connection is secure, test the room temperature sensor with a multimeter to check for an open circuit or an out-of-range resistance reading, and replace the sensor if it has failed.

If the fix is simply reseating the CON5 connector, there may be no parts cost, though a service call typically runs between $75 and $150 for labor. If the room temperature sensor itself needs replacement, parts and labor combined generally range from $100 to $250. Control board replacement, if needed, is more expensive and can range from $200 to $450 depending on the model.
