What F10 means

On LG electric and gas ranges with a numeric F-code display, F10 is listed as a door locking system failure for the upper oven. The latch motor and switch hold the door shut when the oven needs it locked, and F10 means the control cannot confirm the lock. The oven may not start a locked function, and the door may feel stuck or may not latch at all. The list ties it to the upper oven only.

Common causes of F10

The upper oven latch motor not moving the lock
A lock switch that does not report its position
A latch mechanism that is binding
A control that is not getting the lock signal

✓ One safe check you can try

1. Press CLEAR/OFF, then start the same function once more. 2. If the code returns, turn the range breaker off for 30 seconds, then on again. 3. Do not force the door open or pry at the latch. Let the oven cool fully first.

! Why to stop there

F10 does not say whether the latch, the switch, or the control is the cause, so we test the lock circuit in order.
Forcing the door can bend the latch and turn a simple repair into a larger one.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F10F10 questions

What is F10 telling me on this range?

The upper oven's door locking system failed to confirm its lock. The oven cannot trust the door position, so it stops the function. The control is guarding the door, so do not force it open.

Is the door stuck shut?

It can be. Wait until the oven is cool, and do not pry the latch. If it stays locked, call us. Keep the oven off and leave the latch alone until it is cool.

Will resetting the breaker help?

A 30-second breaker reset can clear a one-time lock glitch. If F10 comes back, the latch needs testing. It takes half a minute and is safe to try once.
