LG Refrigerator Error Code Er SS — Pantry Sensor / Secondary Sensor Error
What this means
The Er SS error code indicates a problem with a secondary temperature sensor, typically in the pantry drawer, convertible zone, or a secondary compartment. This sensor monitors the temperature in specialized storage areas that can be set to different temperatures. A faulty sensor prevents proper temperature regulation in that zone.
Alternate codes: SS
Step-by-step fix
3 stepsIdentify the affected zone
Determine which compartment the error refers to — the pantry drawer, convertible zone, or another secondary compartment. Check the temperature in that area with an external thermometer to see if it's abnormally warm or cold.
Locate the sensor
The secondary sensor is usually located inside the affected compartment, often near an air vent or clipped to the compartment wall. Remove any drawers or shelves to access it.
Test and replace the sensor
Unplug the refrigerator. Disconnect the sensor's wire connector and test with a multimeter. At the expected compartment temperature, check the resistance against an NTC thermistor chart. Replace if the reading is abnormal.
When to call a professional
If the sensor tests normal, the control board's input for that sensor zone may be faulty. A technician can diagnose whether the board or wiring is at fault.
