My control pad started to turn the oven on and off at first. I tried to reset it which didn't work. Now only some of the buttons are working but the buttons that do work do not do what it is indicated. Example push the number buttons and the oven just turns on and off then the other oven will do the same. The clock registers time but that is about it. I called Jenn-Air and they said that it might now be the control pad. I looked at the diagram of the top of the stove and it appears to be the only thing that would be wrong with it. Is this something that I can just plug into the back of the unit and repair myself? Could this be the only thing wrong with it? It is a 190$ part?
