What F27
actually means.
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.

What to do when F27 shows on the stoveKind of codeControl 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 toControl 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 asStove 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.

Before you book,
in this order.
Each step comes from LG's own guidance for F27 on its stoves. Follow it to the end: the last card says whether this is a visit.
Let the oven cool completely before you touch the door.
Flip the stove's breaker off, count 30 seconds, then flip it on.
Do not start self-clean again until the fan is checked; book a visit if F27 returns.
Still there?
It usually turns into control board and display repair. Book with the code and the model number.
What not to do
F27 has nothing to do with the fan you can see at the back of the oven. It names the hidden fan that keeps the control electronics cool.

In LG's own words
F27 indicates a Cooling Fan Stalled or Locked During Self Clean
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. 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.

Still showing F27?
Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
