Kenmore Refrigerator Error Code Er SS

Er SS means the control board has detected a short circuit or disconnection in the pantry sensor circuit. The pantry sensor is a thermistor that monitors the temperature of the pantry or flex-temp compartment. When the board cannot get a valid reading from this sensor, it displays Er SS to indicate the circuit has failed or lost connection.

The main refrigerator and freezer compartments will generally continue to function with Er SS active, but the pantry or flex-temp compartment will not be temperature-controlled properly since its sensor is not working. Avoid storing temperature-sensitive items in the pantry drawer until the fault is resolved. Address the error promptly to prevent food spoilage in that zone.

Unplug the refrigerator, disconnect the pantry sensor connector, and use a multimeter set to measure resistance (ohms). At room temperature, most refrigerator thermistors read somewhere in the range of 5,000 to 20,000 ohms, but check your specific model's service manual for the exact value. A reading of zero ohms indicates a short circuit, and a reading of infinite resistance (OL) indicates an open circuit. Either result confirms the sensor has failed and needs to be replaced.

Start by locating the pantry sensor, which is typically mounted inside or near the pantry drawer compartment, and check that its wiring harness connector is firmly seated. Unplug the connector, inspect it for corrosion or bent pins, and reconnect it securely. If the error returns, use a multimeter to test the thermistor resistance and compare it against the specification in your service manual. A reading that is open or shows near-zero resistance confirms a failed sensor that needs replacement.

If the fix is simply reseating a loose connector, there is no parts cost. A replacement pantry sensor thermistor typically costs between $15 and $40 for the part. If the wiring harness needs replacement, expect to pay $20 to $60 for the harness. A main control board, if it turns out to be the cause, runs $100 to $250 or more. A technician service call adds $80 to $150 on top of parts, depending on your area.
