This repair was easy, but I would not have even tried if I hadn't read the tips from other DIYers - thanks! The website questions and schematic along with some common sense testing isolated the problem with the oven only heating up to 250 degrees. Since the broiler (upper element) worked ok, that made it likely that the temperature sensor was not the problem. That made almost certain that the bake (cooking) element was the problem. So, I ordered the part, which was delivered quickly. Early on the morning of the scheduled delivery date, I turned off the oven power at the fuse box and pulled the oven away from the wall. There were only 4 screws to remove in order to take off the rear panel. The bake element was attached to two slide-on connectors, one of which looked charred and partially disconnected. I cleaned the charred connector, reattached it to the bake element, turned the power back on, and then turned the oven on. The charred connection glowed, so I immediately turned off the oven and the power. I disconnected the bad connector, cut it off from the wire, and stripped the wire to prepare for a new connector, which cost 30 cents at the hardware store. The bake element connection was cleaned, and then the new connector was attached. The power was turned back on, and then the oven was turned on, and it heated perfectly. After confirming several heatings over several hours, the rear panel was reattached, and the oven was pushed back to the wall. This expensive 40" dual fuel oven had been purchased new and used for 3 years by the prior owners of our home. The oven's computer brain died when the oven was 7 years old - the repair cost us $500 for professional labor, parts, and materials. I don't know if I could have done that repair, but I had no intention of shelling that much again, which is why I tried this bake element repair myself. The oven is now 11 years old, and the most likely part to fail is the original bake element. So, we may keep the new part as insurance with the hope of making a fast, easy, inexpensive repair when the original bake element eventually fails.
