What Does Error Code F5 Mean on a LG Oven?
Door latch failure during self-clean cycle.
F5 fires when the control board commands the motorized door latch to lock or unlock during a self-clean cycle but does not see the expected confirmation from the latch position switch within the allowed time. The board interprets the missing feedback as a failed lock operation and halts the cycle. This differs from related door codes in that it specifically involves the self-clean latch motor and its switch, rather than a general door-open sensing fault during normal baking.
