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. LG range display · also shown as F52, F56, F59 What to do when F51 shows on the range ### Kind of code Surface 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. ### Usually leads to Surface element and glass top repair 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 as Range 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. ### Make LG A Korean electronics group selling freestanding and slide-in ranges on gas, electric and induction, many with Wi-Fi. ### Source LG Help Library "LG Range - Error Codes List" (Wayback copy, 23 Jun 2025) Only on LG ranges with a griddle.

Switch the breaker off, wait 30 seconds and restore power to clear F51. If it comes back, it needs a visit. ### Why does my LG range show F59 when the griddle feels warm? F59 means the griddle is not heating properly, not that it is stone cold. Heat that builds too slowly can trigger it. ### Is F52 on an LG range the same as F51? Both are griddle sensor codes; LG adds that F52 is a short that was detected. The fix path is the same: reset, then service if it returns. --- **[Read on the site: LG range showing a griddle code F51 to F59](https://rangerepair.center/error-codes/lg-f51/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
