Cooktop error code F3
LG cooktop error code F3: Capacitive touch controls read a change in the panel, and anything conductive sitting on them reads as a finger that never lifts. Every spelling LG publishes for it, which machines can raise it, and what to do next.

What we can confirm
Code F3, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
F3
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.

What it narrows down to
The touch controls are reporting a key that is stuck or wet

What else belongs to the cooktops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

An induction zone cannot measure its own temperature
Not an error — the glass is above 150°F and the cooktop is saying so
The supply to the appliance was cut while it was working

About 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, 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 and describe what the panel is doing before booking anything.
