The Oven was installed in 1987. I replaced the Oven Baking Element in 2008 using a part from AppliancePartsPros8 Pros. Fixed the problem. The oven started experiencing the same issue again, now 14 years later. I purchased another Oven Baking Element, which again fixed the problem. Followed the video on generic Oven Baking Element replacement - 4 screws was all it took. Easy. Working again like new.
