Admiral Electric Oven

I have an Electric Admiral stove (must be 20+ years old)and the top 4 burners all work but the oven burner and the Grilling burner inside the oven won't turn on. When I turn the knob for the oven the light which indicates that the oven is on will not illuminate.

I may have inadvertantly pressed/turned the clock/timer dials when I was cleaning the stove (clock doesn't work by the way) and I have since attempted to jiggle and turn the dials to see if the problem lies there but to no avail.

Any suggestions?

Thanks...
