Frigidaire wall oven suddenly not working.?

My Frigidaire wall oven suddenly stopped working. When I turn both dials to "bake" then suddenly the light works, the clock works but when I turn the dials to off position everything doesn't work again. Are there fuses in this oven? I checked the manual but don't see any solution. Also when I turn the dials to bake the elements don't work either. I have changed elements in ovens before, but it seems odd they would both stop working at same time. It happened right after I broiled something. Was working fine then nothing.
