LG Refrigerator Error Code E-gS

The E-gS code means the room temperature sensor has a detected fault, specifically an open or short circuit in its wiring. This sensor monitors the ambient temperature around the refrigerator and sends that data to the control board. When the board cannot get a valid reading from the sensor circuit, it triggers this code. The first diagnostic step is to inspect the sensor wiring and use LED CHECK mode to confirm the fault.

The refrigerator may continue to run with this code active, but its ability to regulate cooling based on ambient temperature will be compromised. Food safety could be affected if cooling performance degrades significantly. It is best to address the fault promptly rather than operating the unit for an extended period with a faulty sensor.

If only a wire repair or connector cleaning is needed, costs can be minimal, generally in the range of a few dollars for supplies. If the room temperature sensor thermistor requires replacement, parts typically range from around $15 to $50 depending on the model. Adding professional labor, the total repair cost usually falls somewhere between $100 and $250.

In some cases, yes. If the issue is a loose connector or visually damaged wire, a knowledgeable DIYer can inspect and reseat connectors or repair wiring. If the thermistor itself has failed, replacing the room temperature sensor is a moderately accessible repair. However, using LG's LED CHECK mode to confirm the fault before purchasing parts is strongly recommended.

A reset may temporarily clear the code from the display, but if the underlying wiring or sensor fault is still present, the code will return once the control board runs its diagnostic checks again. A permanent fix requires repairing or replacing the faulty wiring, connector, or sensor thermistor.
