Ok, then you must of had a problem preheating the oven for bake for this display issue started and you just forgot about it, because it makes no sense why solving one problem makes another problem. LOL
If you put your oven on BAKE at 350 degrees, it will take about 20 minutes for it to preheat, that's on all ovens, including my Maytag in my Kitchen.
So I went to run the multimeter on the element terminals and found, behind the shield that covers the sensor and all that, a wire that was unplugged. Strange because I had never gotten into this area ever.
Plugged it in, tested a preheat and it works!
