Googled the problem and was brought to this site. Saw stories describing my exact problem, and suggesting the problem was Oven Thermal Fuse. Made sense. Removed side trim (screws accessed through lower oven). Removed control panel (screws uncovered after removing trim) and found fuse. Ordered it. Came in two days. Did the trick. Really appreciate the access to other's experiences (to help with diagnosis) and ease of ordering / prompt delivery.
