On the covered LG range or oven, F3 means a Touch Pad Sensor Key Error — LG's own wording. First, note which pads respond before cutting power. Then: switch the unit's circuit breaker off, wait 30 seconds and switch it back on — LG's own sequence for this code; there is no CLEAR/OFF step for it.

Record this first — changing settings destroys the evidence
- Note whether any pad responds before you start troubleshooting
- Whether the panel is wet or covered
Try in this order
0 of 10 completedWhat to do first
ReversibleNote which pads respond before cutting power.
Correct only the documented fault domain
ReversibleSwitch the unit's circuit breaker off, wait 30 seconds and switch it back on — LG's own sequence for this code; there is no CLEAR/OFF step for it.
Clear the panel
ReversibleWipe the control panel dry and remove anything resting on the touch pads.
Reset at the breaker
ReversibleTurn the circuit breaker to the unit off, wait 30 seconds and turn it back on; LG gives this as the step for F3.
Clean the touch pad
ReversibleF3 appears when the control thinks a key has been held down for over a minute. Wipe the pad with a slightly damp cloth: grease or moisture from a boiling pot can fool the sensor.
Switch the breaker off for 30 seconds
ReversibleLG's help library says to turn the circuit breaker off, wait 30 seconds and turn it back on.
Note which pads respond
ReversiblePress each pad gently and write down which ones respond, stick or do nothing before you cut the power.
Dry and clean the panel
ReversibleSwitch the power off, wipe the panel with a barely damp cloth and let it dry fully, since moisture or grease under a key can read as a press.
Reset the breaker
ReversibleSwitch the breaker off for 30 seconds and back on, which is LG's own sequence for this code.
Ask for panel service if it returns
ReversibleA code that comes back with nothing touching the panel means the touch pad or its ribbon connection needs service.

Exact questions
Common questions
What does F3 mean on a LG range or oven?+
a Touch Pad Sensor Key Error — LG's own wording.
Is the upper oven F1 the same?+
No; F1 is a thermistor error.
What is LG's step?+
The breaker reset for 30 seconds, then service.
Can I clean the pad with a spray cleaner?+
Use a damp cloth only and dry the panel, because liquid sprayed onto the pad can reach the electronics.
Can a wet cloth cause F3 on an LG range?+
Moisture or grease on the glass touch pad can read as a key held down, so dry the pad completely after wiping.
Why does F3 appear after cleaning the control panel?+
Moisture or cleaner under the touch pad can make a key read as pressed. Switch the power off, let the panel dry fully and try again before assuming a fault.
Does F3 stop the oven from working?+
It can lock out the keypad functions that depend on the affected key, so some functions may not be available until the pad is cleared or serviced.
