What to do when F-9 shows on the ovenKind of codeHeating
The control asked for heat and the cavity did not warm the way it expected. A bake or broil element that has opened or blistered is the usual answer; the wiring to it and the relay that switches it are checked before a board is blamed.

An electric oven that stays cold, bakes only from above or will not broil, traced to the element, its terminals or the relay that feeds it.

Before you book,
in this order.
Each step comes from LG's own guidance for F-9 on its ovens. Follow it to the end: the last card says whether this is a visit.
Turn off the function you were using so the display clears and the beeping stops.
Set the oven again and see whether it heats.
If F-9 comes back, write down the code and book a visit.
Still there?
It usually turns into bake and broil element repair. Book with the code and the model number.
What not to do
F-9 is not a temperature calibration issue. An oven that heats but runs a little hot or cool is adjusted in the settings, not cleared as a code.
