Turns out this was our second oven this month that would not heat up. However, this one was easier. We had a small fire in the oven on the lower bake element, and the next day the oven would not work.There were two screws holding the element into the back of the oven. I unscrewed them and pulled the element out and it broke. So, I knew what was wrong!
I ordered a new element from ApplianceParts on Saturday evening, with regular shipping. It arrived Tuesday and I replace the old one than night.
