F3
LG F3 on an oven: touch pad key error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On an LG range, F3 means a touch pad sensor key error. LG says to switch off the unit's circuit breaker, wait 30 seconds and switch it back on; if the code stays, the unit needs service.
Safety first
Stop and check this first
- If a key acts on its own, the oven or cooktop can switch on without you asking: keep the breaker off until it is checked and leave nothing on the range.
Safe checks you can perform
- Clean, clear panel
- 30 second cut
- Keys that do not respond
Leave these tasks to a qualified professional
- Do not attempt this professional task: Touch pad test
- Do not attempt this professional task: Running test after the repair
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Touch pad test
What they doThe technician tests the panel key by key and, with the range disconnected, checks the connection between the panel and the control.
They must show youwhich key or connection was failing.
In writingwhat was checked, any part replaced with its reference and the reason.
Running test after the repair
What they doThe technician sets several functions from the panel and leaves the range on long enough to see whether F3 returns.
They must show youthe panel responding with no F3.
In writingthe functions tested and the result.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Clean, clear panel
- Who:
- you, with a dry cloth and the oven cold.
- How:
- remove anything from the panel and dry it with a cloth and no liquid cleaner. Do not use lots of water on the keys.
- Result that matters:
- that nothing is touching the keys.
- If something was on it or it was damp:
- leave it clean and go on to the power cut.
- If it was clean and dry:
- go on to the power cut anyway.
- Evidence to keep:
- photo of the panel before and after.

30 second cut
- Who:
- you, at the breaker panel.
- How:
- switch off the range's breaker, wait 30 seconds and switch it back on, as LG advises for F3.
- Result that matters:
- whether F3 returns after the cut.
- If it does not:
- it was a one-off.
- If it does:
- LG says the unit will require service.
- Evidence to keep:
- note of the time and the result.

Keys that do not respond
- Who:
- you, no tools.
- How:
- if the panel can be used, press each key once and note which does not respond or acts on its own.
- Result that matters:
- giving the technician the exact key.
- If one key fails:
- note it.
- If none respond:
- tell the technician; it may be the panel connection or the control.
- Evidence to keep:
- list of keys that fail.

What it means
LG defines F3 as a touch pad sensor key error. The control monitors the keys and warns when it detects a press that does not make sense, such as a key that seems held all the time, or an invalid reading. Something on the panel, moisture, the panel itself or its connection to the control can cause it, and the code does not tell them apart. LG says to cut the breaker for 30 seconds and, if it stays, book service. The table is LG's US range error code list; check your model's manual to confirm the code means the same.
