Replaced the oven bake element and the sensor. I don’t think that the sensor was faulty, but replaced anyway.
The replacement was fairly easy, but there are 2 clips that hold the element and the element’s front crossbar will snag on the clip that holds the rear cross member. To solve this and prevent the rear clip grabbing the front cross member, used a saw as a guide to cover the rear clip and act as a ramp for the element. Once the front cross member has passed the rear clip, the saw can be pulled out. A long ruler could be used instead.
