out of the blue, my oven controls, clock and timer are blank so I cannot set them. the nightlight works (there is a rocker switch that works fine) but that's not too helpful for baking.

Ground is good and the circuit breaker never tripped. The stovetop works fine - all four burners work. I am thinking a circuit board went bad (unless there is a fuse or something like that in there). Any thoughts/advice how to trouble shoot an otherwise perfectly good Stove/oven?

thanks
