Burner stays on Red hot.

LG double electric oven. Glasstop burner went red hot and stayed that way. Only way to stop it was to unplug it or go to the breaker box. From what I’ve read it could be an infinite switch? If so, how would I know if that is the issue? (Model number LDE3017ST)

Answer this question I have this problem too

Is this a good question?

@deric81 remove the cover from the cook top display PCB and see if there are any obvious damaged parts on the PCB. Post pictures Adding images to an existing question of what you find so we can see what you see. This sounds like either a bad control board, stuck closed relay or bad thermostats.
