What to do when F51 shows on the stoveKind of codeStovetop elements
A burner on an electric or induction stovetop did not heat the way the knob or key asked, heated with nothing set, or ran hotter than the setting. The pan, a lock left on and the switch behind the knob are checked before the element under the glass, its limiter or an induction board is changed. If a burner keeps heating after it has been switched off, turn the stove's breaker off before anything else.

Before you book,
in this order.
Each step comes from LG's own guidance for F51 on its stoves. Follow it to the end: the last card says whether this is a visit.
Turn the griddle zone off and let it cool.
Make sure the griddle plate sits flat and in its proper place.
Flip the stove's breaker off, count 30 seconds, then flip it on.
Book a visit if the griddle code returns.
What not to do
F51 is not a general stovetop shutdown. It belongs to the griddle zone, so the other burners or zones can often still be used.
