LG Range Code F27: Cooling Fan During Self Clean

Medium · inspection needed

Code: F27
Appliance: Range
Brand: LG
Warranty: 30-day workmanship

What F27 means

On LG electric and gas ranges with a numeric F-code display, F27 is listed as the cooling fan stalled or locked during self clean. The cooling fan keeps the control area from overheating while the oven runs at self-clean temperatures. If the control does not see that fan turning, it ends the cycle and shows F27 for protection. The oven is usually very hot when the code appears.

Common causes of F27

The cooling fan not turning
A fan wire or connector that is loose
A fan blade that is jammed
A control that stops sending power to the fan

✓ One safe check you can try

1. Let the oven cool fully before you do anything else. 2. Switch the circuit breaker off for 30 seconds and back on. 3. If F27 appears again on the next self clean, stop using self clean and call us. 4. Keep pets and children away from the hot oven until it has cooled.

! Why to stop there

Self clean runs very hot, so a stopped fan matters, and we test the fan circuit before it is used again.
We check whether the fan runs at other times, because that tells us if the problem is the fan or its control.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F27F27 questions

What does F27 mean?

The cooling fan stalled or was locked during self clean. The control stopped the cycle to protect itself. That protects the control area from the heat of a self-clean cycle.

Is the oven hot when F27 shows?

Very likely, since the code appears during self clean. Keep children away and let it cool. Self clean takes the oven to very high temperatures.

Can I run self clean again?

Not until the fan is checked. A fan that stops under self-clean heat can let the control area overheat. We test the fan first, then you can run another cleaning cycle.
