Turn off the function you were using so the display clears and the beeping stops. If it comes back, it needs a visit. ### Can I clear F-9 on my LG wall oven myself? You can clear the display by turning the function off and setting the oven again. If the oven still does not heat and F-9 returns, the cause is inside the oven and needs a visit. ### Does F-9 on an LG oven mean the element is gone? LG names only the result, an oven that is not heating. The element, its wiring and the control are all on the list, which is why they are tested before anything is ordered. --- **[Read on the site: LG wall oven showing F-9 | OvenRepair.center](https://ovenrepair.center/error-codes/lg-f-9/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
