Answer to continue safely

Is it safe to keep using?

Maybe. The main refrigerator and freezer compartments are unaffected by SS and continue to cool normally. However, do not rely on the pantry zone for temperature-sensitive storage until the sensor is repaired.

Can I reset the code?

Yes. A power reset may clear a transient SS caused by a loose connection. If SS returns, the sensor thermistor or wiring requires physical inspection and likely replacement.

When to stop immediately?

Stop if you notice: Food in the pantry drawer has frozen despite being set to a non-freezing mode, indicating runaway cooling from an unmonitored zone., SS persists after multiple power resets and drawer wiring inspection, confirming the sensor element has failed..

Symptoms You May Notice

Pantry or flex zone not holding its set temperature

Food stored in the pantry drawer — deli meats, wine, or specialty items — is either too warm or too cold because the control board cannot read the zone temperature and regulate cooling to it.

Pantry zone temperature mode cannot be changed

The control panel's zone selector becomes unresponsive or the selected mode does not change the actual temperature in the drawer, as the board refuses to regulate a zone with a failed sensor.

SS code on the display or in service diagnostics

The error is displayed on the refrigerator's main panel or identified through the service diagnostic mode, pointing specifically to the pantry sensor circuit.

Ice forming in the pantry drawer when set to non-freezing mode

With no sensor feedback to stop cooling, the pantry zone can drop below freezing, damaging produce or wine stored there — a sensor short often causes runaway cooling rather than no cooling.

Possible Causes

1

Failed pantry zone thermistor

The sensor's thermistor element has shorted (resistance near zero) or opened (infinite resistance) from age and thermal cycling, producing an invalid reading that triggers the SS fault.

Requires Professional
2

Pinched or cut sensor wiring harness

The sensor wire routed along the pantry drawer runner is pinched by the drawer mechanism or abraded against a metal edge, creating a short circuit or open break in the wire.

Requires Professional
3

Loose harness connector at sensor or control board

The small plug connecting the sensor harness to the control board or to the sensor itself has worked loose from vibration, intermittently breaking the sensor circuit.

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Power reset the refrigerator

    Unplug the refrigerator for 60 seconds and restore power. Allow the control boards to reinitialize for 3 minutes, then check if SS has cleared. A loose connector may reseat during the reset.

  2. 2

    Remove the pantry drawer and inspect the wiring

    Pull the pantry drawer fully out of its cavity and look at the wiring harness that runs along its sides or at the rear of the cavity. Check for any area where the wire appears pinched, kinked, or rubbed through. Gently reposition any wires that appear under stress from drawer movement.

  3. 3

    Move pantry food contents temporarily

    Remove items from the pantry drawer and store them in the main refrigerator compartment while the SS fault is unresolved. With no sensor feedback, the pantry zone temperature is unpredictable and could damage sensitive foods.

When to Call a Professional

Contact a qualified technician if:

  • Resistance measurement of the pantry sensor is near zero ohms (shorted) or unmeasurable (open), confirming the thermistor element has failed.
  • Visual inspection reveals the sensor wire is abraded through its insulation where it runs across a metal drawer runner edge.
  • SS clears after a reset but returns within one temperature cycle of the pantry zone, confirming an intermittent sensor failure that will become permanent.
