Kenmore Refrigerator Error Code Refrigerator Sensor (2)

This error code means the main control board has detected an abnormal signal from the secondary refrigerator temperature sensor located in the middle section of the refrigerator compartment. The board has identified either a cut wire (open circuit) or a shorted wire on this sensor's circuit. The first diagnostic step is to check connector CON7 on the main PCB for a loose or faulty connection.

The refrigerator may continue running, but with a faulty temperature sensor the control board cannot accurately monitor the middle compartment's temperature. This raises the risk of inadequate cooling or temperature swings that could affect food safety. It is best to address the fault promptly and monitor food temperatures closely in the meantime.

A power reset may temporarily clear the error code from the display, but if the underlying wiring fault or sensor failure is still present, the code will return. The error is triggered by a real electrical condition (open or short circuit) that the board will continue to detect on every power cycle. Clearing the code without repairing the fault does not restore accurate temperature monitoring.

In many cases, yes. Start by unplugging the refrigerator and inspecting connector CON7 on the main PCB for looseness, corrosion, or damaged pins. If the connector looks good, trace the sensor wiring for any visible breaks or pinches. Testing the thermistor with a multimeter requires basic electrical knowledge but is within reach for a confident DIYer. If the main PCB itself is faulty, board replacement is more involved and may warrant professional service.

Repair costs vary depending on the root cause. A replacement NTC thermistor sensor typically costs in the range of $15 to $50 for the part. A new wiring harness or connector repair may add modest labor cost if professional service is needed. If the main PCB requires replacement, total costs including parts and labor can range from $150 to $400 or more depending on the model and service rates in your area.
