The LDE3019ST is an LG freestanding electric range, sold under the LG STUDIO badge. Discontinued — 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. On this platform, the F3 fault code is one of the more common reasons it gets a service call.
Service calls on this range most often trace to one of a short list: the F3, F5 or F7 fault codes. We confirm which one applies against the model and serial number before ordering a part.
