The bottom heating element in my oven burned out. I turned the oven off but did not throw the circuit breaker when I removed the burned out element. As a pulled the heating element out one of its electrical leads shorted out when it touched the oven wall and spot welded itself to the side of the oven. Interestingly, the short didn't cause the circuit breaker to trip. I was able to free the spot-welded lead from the side wall of the oven. I got a new bottom heating element and installed it. When I turned the oven on the bottom element didn't get hot although the top one did. I am guessing an electrical component related to the bottom element burned out but I don't see any fuses or on board circuit breakers in the electrical schematic for the oven. Can anyone tell me how to get the oven working again? Thanks. Mark

There is no fuse or circuit breaker in the oven other than a thermal fuse located near the door lock. If it fails, then both the bake and broil elements would no longer function. So if you are only having a problem with the bake element, I would suspect the relay on the control board was damaged when the circuit was shorted to the chassis and now can no longer actuate the contacts. You may want to verify the connector is still in good shape as well as the wiring to the control board for any damage. If you want to test the circuit, you can swap the wires on the control between the bake and broil and see if the bake element starts to heat when broil is selected. If it does, then it looks like the board is the problem.

Thanks Brian. That seems like a great answer. How do I access the control board?

It's behind the user interface. Look for some screws holding the trim in place, that can be removed allowing the top trim to come off. Then the user panel can be tilted toward you allowing access to the control panel.

It turns out there is a high limit switch mounted on the back of the oven that connects to the wire that leads to the bake heating element that had burned out. I would never have figured it out without your help! I Ordered the part from AppliancePartsPros today (btw, I got the replacement burner from you as well). Thanks.

Glad I could help. Those high limits can be annoying when they fail, but it is much cheaper than a control board.
