LG uses F27 when the cooling fan stalls or locks during self clean. That fan keeps the controls cool while the oven runs very hot, so the range stops the cycle. LG range display What to do when F27 shows on the range ### Kind of code Fans The convection fan behind the oven's back wall, or the cooling fan that keeps heat away from the controls, did not spin as fast as the control expected. Grease on the blade and a loose plug are checked first; a tired motor, and on the cooling side a thermal fuse, come after. ### Usually leads to Convection fan repair A convection oven on a range that bakes unevenly, rattles, squeals or never starts its fan, traced to the motor, the blade or the convection element. ### Shows up as Range Self-Clean Problems The self-clean cycle will not start, stops partway, leaves the door locked, smokes heavily, or leaves the oven dead afterward. ### 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 F27 without naming the models that use it. ## Before you book, in this order.

Switch the breaker off, wait 30 seconds and restore power to clear F27. If it comes back, it needs a visit. ### Why does my LG range show F27 only during self-clean? That is when LG checks the cooling fan. The control protects itself during the hottest cycle. ### Is it safe to keep baking on an LG range that showed F27? Normal baking is less hot than self-clean, but the same fan cools the controls. Have it checked before the next self-clean. --- **[Read on the site: LG range showing F27 during self-clean | RangeRepair.center](https://rangerepair.center/error-codes/lg-f27/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
