I replace the bake element. The element is hidden, so replaced through the back. I had to cut through the insulation then bend a thin aluminum cover after removing the exterior cover plate. It was not difficult - only time consuming, but I was taking my time because documentation is limited and this was my first repair of a hidden element. The oven is 8 years old. I was shocked how badly warped the old element was from use. My ohm meter needle didn't move at all, so there was zero continuity. No wonder if it didn't work. I wonder if the element being inserted into a narrow slot shortens the life expectancy. I made myself a calendar reminder to replace it in five more years.
