We have a combination Jenn-Air Microwave/Oven. When we returned from vacation, the clock display on the oven was black. The touch panel still works & beeps when the oven temp is set. The oven light works. The oven cooks fine. As long as we touch the correct numbers to set the oven temperature, all works fine. It's just that the display is all dark. Nothing. No clock, no temperature, nothing. Is there a reset button? It's possible we had a storm while we were gone, but am not sure.

Any ideas??
