During self-clean, a fan keeps the controls and the stove body cool. LG's F27 means that fan stalled or locked, and the cycle stops so the electronics do not overheat. LG stove display What to do when F27 shows on the stove ### Kind of code Control board and power The main board failed its own start-up check, lost contact with the display, or saw the supply voltage sag too low, often after a storm, a power outage or a spill that ran down behind the panel. The breaker, the cord and the outlet are ruled out before a board is replaced. A stove that sparks, smells of hot wiring or keeps heating while this code shows is switched off at the breaker first. ### Usually leads to Control board and display repair Stoves with a blank or flashing display, touch keys that do not answer, codes that keep returning or a stove that will not turn on, traced to the board, the keypad or the power to them. ### 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) For F27, the source is this: 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.

Let the oven cool completely before you touch the door. If it comes back, it needs a visit. ### Is it safe to bake on my LG after an F27 during self-clean? Normal baking is gentler than self-clean, but the cooling fan still protects the controls. Have it checked before long bakes. ### Why did the LG cooling fan stop only during self-clean? That is when the fan works hardest. A worn motor or something blocking the blade shows up then. ### My LG smelled hot and then showed F27. What should I do? Turn it off and let it cool. If you see smoke from the controls or wiring, switch the breaker off and book a visit. --- **[Read on the site: LG stove shows F27 during self-clean | StoveRepair.center](https://stoverepair.center/error-codes/lg-f27/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
