My wall mount oven is a 1992 GE Dual Wave 2. It is built into a concert wall. So I didn't want to replace. I would never find one to match up. So I began researching. What did I have to lose? I ordered the burner. It came quickly. I took the shelves out. Turned off the breaker. It was just 2 screws. Took the old one out. Put the new one in. It was easy. Turned the breaker on and turned the oven on. IT WORKS! I let it heat for about 30 minutes. Now the true test will be, I have had to use the oven on 450 for a long time no matter what. We will see.
