# Range error code F11

### What F11 means on this make

Ranges and wall ovens carry more than one board — the main relay board and the touch control — and this says the link between them has dropped. As on the refrigerator, the machine will sometimes carry on doing what it was last told while refusing to accept anything new, which is an unnerving thing to have happen with a hot oven. It is worth clearing at the breaker rather than at the panel, because the point is to power both boards down together.

### 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

- Press CLEAR/OFF first.
- Turn the breaker for the appliance off for thirty seconds, then on.
- If the oven is hot and unresponsive, leave the breaker off until it cools.
- Book it if it returns.

### 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.
