I saw that the element was failing - an ultra bright section of NiChrome wire in the bake element. Two day's later sizzling noises...pop, then dead wire. Power was there. Oven light worked. Just no heat. Ordered new element.
Next day element arrived. Set breaker to off. Removed 2 screws on element. Pulled element forward to access the wiring. Unseated the clips. Removed the old element. Replugged the clips. Pressed the element back into the insulative batting. Reinstalled the screws. Set breaker to on. Preheated the oven to 400 °F. Made pizza. Yum. Success!
