If neither the oven nor the broiler heats, but the range burners still work, the clock may be set for a timed or self-cleaning cycle. Check to be sure the clock buttons and knobs are set properly. If your clock has a knob that says "push for man(ual)," push the knob in and try heating the oven and broiler again.
