What Er SS means on a Kenmore refrigerator

Er SS indicates the control board has detected a fault in the pantry sensor circuit, specifically a short circuit or an open circuit caused by a disconnected or broken sensor. The pantry compartment relies on this sensor to regulate its temperature independently from the main refrigerator and freezer sections. When the board loses a valid signal from the pantry sensor, it throws Er SS and cannot maintain accurate temperature control in that zone.

For homeowners, the pantry drawer or flex-temp compartment in your Kenmore refrigerator has its own small temperature sensor that tells the fridge how cold or warm to keep that space. If that sensor loses its connection to the control board, either because a wire came loose or the sensor itself failed, the refrigerator does not know what temperature the pantry is at and cannot regulate it properly. This triggers the Er SS code to alert you that something is wrong with that sensor.

The pantry sensor is a relatively small thermistor component with a wiring harness that runs to the main control board. Physical damage to the harness, a corroded connector, or a failed sensor are the most common sources of this fault. Resolving the error requires inspecting the sensor, its connector, and the wiring before replacing any parts.

Common causes of Er SS

  1. 01

    Disconnected pantry sensor connector

    Wiring / connection

    The wiring harness connector between the pantry sensor and the control board can work loose over time, especially if the pantry drawer is frequently removed. A disconnected connector breaks the circuit and immediately triggers Er SS.

  2. 02

    Failed pantry sensor (thermistor)

    Part replacement

    The pantry sensor itself can fail internally, producing a short circuit or an open circuit that mimics a disconnection. A failed thermistor will not return to normal resistance readings even after the connector is reseated.

  3. 03

    Damaged or shorted wiring harness

    Part replacement

    The wiring harness running from the pantry sensor to the control board can develop a short or break due to pinching, chafing, or rodent damage. A damaged harness can cause either a short or an open circuit depending on where the fault occurs.

  4. 04

    Faulty main control board

    Part replacement

    If the sensor and all wiring check out correctly, the input circuit on the main control board responsible for reading the pantry sensor may have failed. This is the least likely cause and should only be considered after the sensor and harness are confirmed to be in good condition.

Frequently asked questions about Er SS

What does Er SS mean on a Kenmore refrigerator?
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.
How do I fix Er SS on a Kenmore refrigerator?
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.
Can I still use my Kenmore refrigerator with Er SS showing?
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.
How much does it cost to fix the Er SS error code on a Kenmore refrigerator?
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.
How do I test the pantry sensor to diagnose Er SS?
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.
