LG uses F11 for a communication error and F38 for a communication error between the main board and the inverter, which drives the induction top. Either way, one board is not hearing the other. LG range display · also shown as F38 What to do when F11 shows on the range ### Kind of code Controls and communication The display, the main board or the induction power board lost contact with one another, or one of them failed its own self-check. A power dip, a loose cable or moisture from a boil-over is ruled out before a board is replaced, and a range that keeps heating while this code shows is switched off at the breaker. ### Usually leads to Knobs, switches and controls Knobs that spin or crack, touch keys that do nothing, blank displays, clocks that reset and control boards that switch the wrong thing. ### Shows up as Range Control Panel Not Responding The touch keys or knobs on the range do nothing, only some keys work, the display is blank or frozen, or it beeps without starting. ### 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) F38 concerns LG induction ranges; F11 applies more generally.

Follow it to the end: the last card says whether this is a visit. 01 Press CLEAR/OFF and try again (for F38, go straight to the breaker). 02 Switch the breaker off, wait 30 seconds and restore power to clear F11. 03 Book a visit if the code returns. ### Still there?

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. --- **[Read on the site: LG range showing F11 or F38 | RangeRepair.center](https://rangerepair.center/error-codes/lg-f11/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
