I have two questions please. One is what is the difference between my # 77001038 and 12002144 please? Two is how could I tell if my faulty burner (only small inner burner working now) is an element issue or a control switch issue?
Both of the elements that you listed look identical but may have a different wattage to them. Normally if the outer element lights up but the inner does not then the issue would be with the element itself. The part number that you would need is 12002144.
How to install right front element ?
Answer Hello Larry. Remove power. Open door and lock the hinges. Remove the door. Look under the front corners and remove the 2-1/4" screws to lift the top. Support the top so it is safe. Note all wires and use a magnifying glass to see all terminals. Use a black felt marker to scribe the burner mount screws so you use the correct stamped burner mount screws upon reassembly. The new burner needs to be centered correctly.
