GE Refrigerator Error Code Er SS

The Er SS error code on a GE refrigerator indicates a pantry sensor fault. The pantry sensor is a thermistor, a temperature-sensitive resistor, located inside the pantry or convertible drawer compartment. The control board continuously monitors the resistance output of this sensor to regulate temperature in that zone. When the board detects a reading that falls outside the expected resistance range, either because of a short circuit driving resistance too low or an open circuit driving resistance too high, it triggers the Er SS code and may disable temperature control for that compartment.

The most common causes involve the wiring harness that connects the pantry sensor to the main control board. Harness wires can develop shorts where insulation has worn through and conductors contact each other or a grounded surface, or they can become disconnected at the sensor connector or at the board itself. The sensor itself can also fail internally, causing its resistance to drift out of specification. Physical damage from ice buildup, moisture intrusion, or mechanical stress on the connector pins are all contributing factors.

Diagnosis should begin at the pantry sensor connector. Inspect the connector for bent or corroded pins, and check the wiring for visible damage. A functioning thermistor will show a measurable resistance that changes with temperature. If the connector and harness check out, the sensor itself should be tested with a multimeter. A reading of zero ohms indicates a short, while an open line with no continuity indicates a broken circuit. If wiring and connectors are intact, sensor replacement is the likely resolution.
