The LSCI307ST is an LG induction cooktop, 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 F1 fault code is one of the more common reasons it gets a service call.
Service calls on this cooktop most often trace to one of a short list: the F1, F5 or F7 fault codes. We confirm which one applies against the model and serial number before ordering a part.
