F11
LG F11 on a range: electronics communication error
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On an LG range, F11 means a communication error in the electronics. Press CLEAR/OFF and try the function again; if the code returns, turn the circuit breaker off for 30 seconds and back on.
Safety first
Stop and check this first
- Do not pull the range out or remove its back cover to check connections: it is a high power mains appliance and only a technician should open it.
Safe checks you can perform
- Code and function in use
- CLEAR/OFF and repeat the function
- Circuit breaker off for 30 seconds
Leave these tasks to a qualified professional
- Do not attempt this professional task: Board connection and supply check
- Do not attempt this professional task: Test after the repair
- Do not attempt this professional task: Board replacement with justification
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.
Board connection and supply check
What they doWith the range isolated, the technician checks the connectors between boards and panel, then measures the electronics supply with a multimeter against LG's specification.
They must show youthe connectors checked and the supply measured against the specification.
In writingwhat was found and what was repaired.
Test after the repair
What they doTo finish, the technician repeats the function that gave F11 and a 30 second breaker reset, and checks the code does not return.
They must show youthe function working without a code after the reset.
In writingthe test carried out, the result and the date.
Board replacement with justification
What they doIf connections and supply are fine, the technician identifies which board is not communicating and replaces it with the correct part for the model.
They must show youthe test that singles out the failed board.
In writingthe part number of the replaced board and the reason.
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.
Code and function in use
- Who:
- you, no tools.
- How:
- photograph the display showing F11 and note what you were using: oven, cooktop, timer or another function.
- Result that matters:
- the code and the function that failed, so you can repeat it later.
- If it appears with a specific function:
- repeat it after CLEAR/OFF.
- If it appears as soon as power comes on or without touching anything:
- tell the technician, it helps narrow down the failing link.
- Evidence to keep:
- photo of the display and a note of the function.
Evidence: LG Range - Error Codes List
CLEAR/OFF and repeat the function
- Who:
- you.
- How:
- press the CLEAR/OFF key and start the same function again, as LG says.
- Result that matters:
- whether communication recovers without cutting the power.
- If it works without F11:
- one-off fault; note the date in case it returns.
- If F11 reappears:
- go on to the breaker reset.
- Evidence to keep:
- note of the result.
Evidence: LG Range - Error Codes List
Circuit breaker off for 30 seconds
- Who:
- you, at the consumer unit or breaker panel.
- How:
- turn off the breaker that feeds the range, wait 30 seconds and turn it back on. Do not open the range or touch its connection.
- Result that matters:
- whether F11 survives a full restart.
- If it does not return:
- use the range normally and watch whether it reappears.
- If it returns or you cannot find the breaker:
- LG says the unit needs service; book the repair.
- Evidence to keep:
- time of the reset and the result.

What it means
LG US lists F11 on its ranges as a communication error, without saying between which modules it is lost. The routine is to press CLEAR/OFF and try the original function again; if it reappears, turn the range circuit breaker off for 30 seconds and back on. If the problem continues or you cannot carry out these steps, LG says the unit will require service. Communication can fail between boards, with the panel or in the wiring that links them, and F11 does not say where.

Symptoms and causes
Probable causes · in order
- One-off communication faultPossible
It clears with CLEAR/OFF or the breaker reset and does not return. No repair needed.
Evidence: LG Range - Error Codes List
- Wiring or connector between modulesPossible
A loose connector cuts communication even when the boards work. The technician checks it with the range isolated.
Evidence: LG Range - Error Codes List
- Control board or panelPossible
If the wiring is fine and F11 persists after the reset, one of the boards is not responding; the technician must identify which.
