I couldn’t find a model number on this Tappan stove but it wasn’t heating and it was easy to tell why. I opened the oven and saw a fried bake element. The element had burned into 2 separate pieces. I had to remove the back of the stove and disconnect the wires to get the burned off part out of the way. Here is a picture of the burned out bake element. The repair was easy as all I had to do is replace the element.
