FAQ

LG WDEP9421S FAQ

On this platform, F2 points at oven temperature sensor fault. Confirm the exact code shown before assuming it is the same fault another LG wall oven would show for the same letters — LG does not use one fault-code scheme across every appliance line.

LG's own US product page still carries this model with an active status flag, read 24 September 2026. Most faults on this platform are isolated to one component rather than the whole unit, so a working diagnosis usually answers that question better than the model's age alone.
