Simon, I figured it out. On page 12 of the Service Manual 16021875 Rev 0, there is Component Testing Information. There is a test procedure for the Child Safety Feature for Child Lockout. By Pressing and holding BAKE and COOK TIME for 10 seconds, the Oven reset itself, and the control panel is now accessible. I guess when the power came on, the Oven went to Child Safety Mode. I happened to start reading the manual from cover to cover to try and figure this out, and noticed the note about "OFF" will display where the temperature normally appears.
