LG defines F3 as a touch pad sensor key error. The control sees a key signal it cannot trust, which can come from moisture as well as a worn key. LG range display What to do when F3 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) LG's range code list (Wayback copy, 23 Jun 2025) carries F3 without naming the models that use it. ## Before you book, in this order. Each step comes from LG's own guidance for F3 on its ranges. Follow it to the end: the last card says whether this is a visit. 01 Wipe and dry the control panel. 02 Switch the breaker off, wait 30 seconds and restore power to clear F3. 03 Book a visit if F3 comes back. ### Still there? It usually turns into [knobs, switches and controls](https://rangerepair.center/services/knobs-switches-and-controls/). Book with the code and the model number. ### What not to do F3 is not the communication code; that is F11. ## What you may notice with it. The range problems F3 tends to arrive with.

Wipe and dry the control panel. If it comes back, it needs a visit. ### Why does LG skip the CLEAR/OFF step for F3? With a key reading wrong, the panel itself may not respond, so LG goes straight to the breaker reset. ### Can steam from a pot trigger F3 on my LG range? Moisture on a touch panel can upset key readings. Dry the panel before the reset, and book a visit if F3 returns on a dry panel. --- **[Read on the site: LG range showing F3 | RangeRepair.center](https://rangerepair.center/error-codes/lg-f3/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
