I'm going to answer my own question: I removed 2 screws and removed the panel holding the display. One the left side, as you face the oven was a small ribbon connecter that had come loose. I pushed in the terminals on both ends of the ribbon connector into their respective recepticles. I put back the panel, making sure that I didn't pull on and/or strain the ribbon as I buttoned it up. Works fine now. Just a loose connection!
