Replaced the thermal fuse. Placed oven in self clean mode and oven quit working less than halfway through clean cycle. After some research, it became apparent that the thermal fuse was likely the culprit. Ordered the replacement part, installed it and after placing the oven back in the cabinet, turned the breaker back on. Oven has worked flawlessly. Bonus: The part didn't cost as much as the local repair supplier and was here just as fast! Square butt driver was handy.
