Does the top oven unit come on while pre-heating? I had the unit checked and it is working o.k. but will not come on in my oven. The bottom unit works fine.
Answer Hello Hal,
In studying the wiring diagram, it is the clocks' designed responsibility to cycle the preheat from the bake to the broil elements. Due to the design of the circuit the two elements will never be on at the same time but if not cycling the broil element on, the control WB27T11312 will have to be replaced.
