Oven bake element. If the oven won't heat, the bake element may have burned out. If the bake element has burned out, it will often be visibly damaged. Inspect the bake element for holes or blisters.
Electronic oven control board. If the oven does not bake or broil then it is possible the circuit board has failed. Both heating elements can be tested to determine if the problem is with the element or the control board.
