Press CLEAR/OFF and try again. If it comes back, it needs a visit. ### My LG range door stayed locked after self-clean with F10. What should I do? Let the oven cool, press CLEAR/OFF, and reset the breaker if needed. A lock that still will not release needs service rather than force. ### Why does my LG double-oven range show F20 and not F10? LG gives F20 to the lower oven's lock and F10 to the upper one. The number tells the technician which door to check. --- **[Read on the site: LG range showing F10 or F20 | RangeRepair.center](https://rangerepair.center/error-codes/lg-f10/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
