LG lists the LRE3021ST as a freestanding electric range. On this platform, the F1 fault code is one of the more common reasons it gets a service call. LG’s own US product page flags this exact model discontinued (read 24 September 2026); it is out of production but not out of the field, and it is exactly the kind of model that has nowhere else to turn for support.
Service calls on this range most often trace to one of a short list: the F1, F2 or F3 fault codes. We confirm which one applies against the model and serial number before ordering a part.
