Oven would not stop heating even with Bake turned off!

The lower element had burned out but in the process, it developed a short from line to neutral. Since the short was located about 3/4 of the total length from the one hot leg (L1) and the other hot leg (L2) was the relay controlled leg, there was a current path that allowed the element to heat even with L2 disconnected by the relay. Actually replacing the element was easy, just remove the back cover(s) and the element mounting screws (2) inside the oven cavity and the new unit slides into place. Reconnect the two wires to the new element and replace the back covers. Back in business and the cookies are coming out perfectly!
