# Range error code F27

### What F27 means on this make

This is the one on the cooking list to stop using the oven over. Self clean takes the cavity far above cooking temperature and the only thing protecting the cabinetry, the controls and the wall behind it is a cooling fan moving air through the shell. If that fan stalls, the heat has nowhere to go. LG’s instruction is to cut the breaker, and that is the right instruction: do not restart a self clean to see whether it happens again.

### Where this appears, and why not to clear it

On the appliance’s own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Turn the breaker for the appliance off. Leave it off until the oven is cold.
- Do not run another self clean until it has been looked at.
- Use the oven for normal cooking only if it will run without the code, and clean it by hand meanwhile.
- Book it promptly. This one is a safety repair rather than a convenience one.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 419-0291](tel:+13054190291) and describe what the panel is doing before booking anything.
