What F51
actually means.
On LG ranges with a griddle zone, F51 and F52 are griddle sensor errors and F56 and F59 mean the griddle is not heating properly. The rest of the range top can be unaffected.

What to do when F51 shows on the rangeKind of codeSurface elements and induction
A radiant element, a coil or an induction zone did not heat the way the control expected, or ran hotter than it should. The pan, the switch behind the knob and the wiring to the element come first; on induction, the power board and the coil under the glass are checked next. A zone that will not switch off, or a crack in the glass, means the breaker goes off before anything else.

Electric zones that stay cold, run too hot or will not switch off, and cracked or damaged glass on radiant and induction models.
Shows up asRange Surface Element Not Heating
One coil or glass-top zone on an electric range stays cold, heats only weakly, or will not respond while the others work.
