LG calls F3 a touch pad sensor key error. Moisture, a spill or a worn key can make the control think a key is being held, and LG's first step for this code is a breaker reset rather than the CLEAR/OFF key. LG stove display What to do when F3 shows on the stove ### Kind of code Knobs, keys and display A key on the panel was held down too long, reported a press nobody made, or stopped answering; or a knob's switch told the stove it was on when it was off. Water, a spill or grease worked in behind a knob is ruled out first, then the switch, the key panel and the cable to the board. If a burner keeps heating while the keys or knobs do nothing, switch the stove off at the breaker. ### Usually leads to Knob and switch replacement Stove knobs that are cracked, loose or spin in place, and the switches behind them that leave a burner stuck on high or dead, replaced at the knob, the stem or the switch. ### Shows up as Stove Display Blank or Flashing The clock and display on the stove have gone dark, or they flash the time, a word or a string of characters and ignore the keys you press. ### Make LG The Korean electronics maker whose freestanding and slide-in stoves often come with app controls. ### Source LG Help Library: range error codes list (Wayback, 23 Jun 2025) F3 is listed here: LG's Help Library code list (Wayback copy of 23 June 2025); the list names no models, so the rating label decides whether your stove can show it. ## Before you book, in this order. Each step comes from LG's own guidance for F3 on its stoves. Follow it to the end: the last card says whether this is a visit. 01 Wipe the touch pad clean and dry. 02 Switch the breaker off, wait 30 seconds and switch it back on. 03 Book a visit if F3 returns once the panel is dry. ### Still there? It usually turns into [knob and switch replacement](https://stoverepair.center/services/knob-and-switch-replacement/). Book with the code and the model number. ### What not to do F3 is not an oven heating or sensor problem. It is limited to the keys you press. ## What you may notice with it.

Wipe the touch pad clean and dry. If it comes back, it needs a visit. ### Why did my LG show F3 after I wiped the panel? Water under the edges of the touch pad can register as a pressed key. Let it dry, then reset at the breaker. ### My LG beeps and shows F3 when nobody touches it. What is happening? As far as the control can tell, someone is pressing a key nonstop. If drying and a reset do not stop it, the key panel needs checking. ### Can I just keep pressing CLEAR/OFF on my LG with F3? LG's step for F3 is the breaker, not the key. Repeated key presses on a stuck panel do not help. --- **[Read on the site: LG stove shows F3 and the touch pad acts up](https://stoverepair.center/error-codes/lg-f3/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
