Supposedly the element receptacle/terminal. The manager of the complex said someone came out and looked at it long ago and said that was what was wrong, but said that he would have a hard time finding a part to fix it.
Personally, I want it fixed as it's the largest burner that is out, even if I have to do it myself. When we move in, I'll test it to make sure that is the problem, but either way, whatever it is, I need the model number for the range. It's hiding from me very well though. Lol
