# Cooktop error code F3

### What F3 means on this make

Capacitive touch controls read a change in the panel, and anything conductive sitting on them reads as a finger that never lifts. LG documents this explicitly: metal objects or water in prolonged contact with the panel will produce a code. A wet cloth folded over the controls while you clean, a spill that has crept under the glass edge, or a pan lid resting on the front will all do it. Dry it and it usually goes.

### 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

- Take everything off the glass and dry the panel completely, including the edges.
- Press the Power ON/OFF key.
- If it comes back, switch the breaker off for thirty seconds.
- A code that survives a dry, clear panel is the touch board, and that is a visit.

### 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.
