Looked online and determined mostly likely part failure was the oven control. I ordered the part on a Monday and it arrived by FED EX on Wednesday. Included with that part , was what I assume to be a surge protector that attached directly to the power leads to the range. The surge protector took about twenty minutes to install and the oven control about 15 minutes. I had looked at a You tube video on how to replace. Glad I did , because I would have had no idea on how to replace the front cover on the control panel. Sticky circuit board cover that had to be removed from old control panel.
