Top bake element is not working. When I set temperature to for ex 350 only heat I get is at from the bottom. Top element does not heat up.
Can anyone tell me what the problem could be?

thanks

Top bake element is not working.
That would be the "Broil Element". Does it work on Broil? Check the element for continuity if it doesn't.

It does not work
Did you check it for continuity? (about 14Ω).

The only errors I can find for LG cooking are F1-F2-F3-F4 and F9 The hidden bake element does work in bake mode, correct? Access the relay board on the back of the machine. It's just above the power cord connection. Set the oven to broil and measure the voltage across broil and DLB-OUT. (220 VAC)

Yes, Rick is correct.

Rick there are a few folks reporting F7 for this issue at AppliancePartsPros, and the oven relay board fixed it:

But like Rick said, disconnect power to your range and ohm test the element first.

These LG models are notorious for the oven relay board going bad and causing this problem. What happens is the heat relay on the board sticks either ON or OFF at times and will throw your temperatures off, or won't heat at all.

Here's the oven relay control board for your model:
Relay Board 6871W1N012B


Its located in the back of your range, so you'd pull your range out from the wall, then unplug it, then remove the back access panel, then you will see it on the lower right side.

Let us know how it goes.

Yes. The hidden bake element works.

Disconnect power to your range then Ohm test the broil element for continuity now.

Here's the broil element for your model:
