As a French 4-door refrigerator, the LRMXS3006S shares its core mechanism with the rest of LG’s refrigerator lineup at roughly 30 cu ft. On this platform, the FF fault code is one of the more common reasons it gets a service call. LG’s own US product page still carries this model with an active status flag, read 24 September 2026.
Service calls on this refrigerator most often trace to one of a short list: the FF, IF or dH fault codes. We confirm which one applies against the model and serial number before ordering a part.
