David M Isom , KY July 23, 2020 Door gasket was bad and lower bake element needed to be changed. The door gasket was a major, the oven is a GE wall unit that was made in 1977. I had to remove the door and completely take the door apart to change this gasket. The bolts to hold it in are internal to the door. You should put a video online to show how to change the gasket on these older units. The bake element, no problem 4 screws and you are done. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
