What F27
actually means.
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.

What to do when F27 shows on the rangeKind of codeFans
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 toConvection 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 asRange Self-Clean Problems
The self-clean cycle will not start, stops partway, leaves the door locked, smokes heavily, or leaves the oven dead afterward.

Before you book,
in this order.
Each step comes from LG's own guidance for F27 on its ranges. Follow it to the end: the last card says whether this is a visit.
Switch the breaker off, wait 30 seconds and restore power to clear F27.
Let the range cool before trying again.
Book a visit if F27 returns; do not run self-clean with a cooling fan that is not working.
What not to do
F27 is not the convection fan in the oven cavity; that is F17.
