What Does Error Code F6 Mean on a LG Oven?
Door lock switch open — door latch not detecting locked position.
F6 fires when the control board commands the door lock and the latch physically travels to the locked position, but the lock switch never sends back the closed-contact signal confirming that state. The board interprets the missing feedback as an open lock switch. This differs from a related latch code that flags a motor or lock that fails to move at all; here the mechanism moves but the switch contacts, alignment, or wiring fail to verify it.
