Questions
about F11.

Can I clear F11 myself?
Press CLEAR/OFF and try again (for F38, go straight to the breaker). If it comes back, it needs a visit.
Does F38 mean my LG induction elements are broken?
It means the main board and the induction inverter stopped talking. The cause can be a harness, the inverter board or the main board, which a technician isolates.
Can F11 on an LG range come from a power surge?
A brief supply problem can confuse the boards, which is why LG starts with a reset. A code that returns after the reset points to wiring or a board.
