What F27 indicates
A cooling fan stalled or locked during self clean is what LG’s list attaches to F27. It sits in LG’s error list for ranges, and no specific model series is named for it.
Steps from the manual
The manual’s remedy for F27 is a power reset: breaker off, a 30-second wait, breaker on.
Continued errors, or an inability to do the steps, mean the range needs service per LG.
