Lg Refrigerator Error Codes — Complete Error Code Diagnosis Guide

Thirteen LG refrigerator codes are indexed here, all sharing the Er prefix, and the ice and water side takes a large share. Er IT, Er IS and Er IF are the ice maker mechanism, its level sensor and its fan; Er gF is the water flow sensor, which stops registering when a filter clogs or a dispenser line freezes. Er FS, Er RS and Er rT are the freezer, fresh-food and ambient thermistors. Er dH and Er DS are the defrost heater and its sensor, Er FF is the evaporator fan, Er CF is the condenser fan, Er HS is humidity, and Er CO is board-to-board communication.

With three thermistors and three fans in one list, the guides start by placing the part the code names, because the diagnosis differs entirely by location: an ambient sensor near the compressor deck fails from heat, a freezer sensor from moisture in its connector, an ice-compartment fan from frost. The defrost pair is read alongside Er FF for the usual reason — frost left by a defrost fault is what stalls a blade. Er gF sends a reader to the filter and the dispenser line before the sensor itself.

Nothing on this list requires opening the sealed refrigerant circuit, which stays regulated work. What several of these codes do require is a decision about the food while the repair is arranged, since a stalled fan or a defrost failure warms a compartment with the compressor running perfectly. Filter changes, condenser cleaning and door checks remain ordinary owner maintenance. EasyBear services LG refrigerators across Sacramento and the Bay Area.
