Lots wrong

I have an LG stove. I have replaced the oven sensor 2 times as the oven temp either gets way to hot and shuts the oven off or it says it is up to temp and it is still cold. The new sensor works for awhile but then they go bad. The large dual burner only works on the outside ring and the other large burner will not shut off. It stays on high so we have to have the stove unplugged. If I replace the 2 control panels on the back #6871W1N009A and #6871W1N011A should this fix all my problems.

Unfortunately LG does not provide access to any manuals nor troubleshooting instructions. Guessing in such situation is not good.
