LG Refrigerator Error Code E IS

E IS on an LG refrigerator indicates an icing sensor error, meaning the control board has detected either a short circuit or a disconnection in the ice maker temperature sensor circuit. This sensor, also called the ice maker sensor or icing sensor, monitors temperature within the ice maker assembly. When it fails or loses its connection, the refrigerator cannot regulate the ice-making cycle and displays this code. If the error appears on its own without any button press, the icing sensor itself is the most likely cause.

The E IS error specifically affects the ice maker system, so the refrigerator and freezer compartments should continue to cool normally. It is generally safe to continue using the appliance for food storage while you diagnose the issue. However, the ice maker will not function properly until the sensor fault is resolved, so expect ice production to be halted or unreliable.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the E IS code, but the error will return if the underlying sensor fault has not been corrected. The code is triggered by an active electrical fault in the icing sensor circuit, so resetting alone is not a fix. The sensor, connector, and wiring must be inspected and repaired or replaced to permanently resolve the error.

Some causes of the E IS error are DIY-friendly. Start by locating the icing sensor connector in the ice maker area and unplugging it, then firmly reseating it to rule out a loose connection. If you are comfortable using a multimeter, you can test the sensor resistance to determine if it has failed. Replacing the icing sensor is a straightforward part swap for most technicians and capable DIYers, though accessing the sensor may require removing the ice maker assembly.

If the fix is simply reseating a loose connector, there is no parts cost involved. If the icing sensor itself needs to be replaced, the part typically costs in the range of $15 to $50 depending on the specific model. If a professional technician is required, expect to pay $100 to $250 or more for a service call and labor on top of the parts cost.
