First, disconnect the power from the electrical box, not just turn off that oven. specially if you have a double oven. Just turn one off is not enough.
I removed the two screws that hold the element in place. I then pulled the element out slowly about 2 inches to expose the connectors, and then disconnected the two wires by holding the wire (female) connector by one plier and pull the element (male) connector out with another plier. Then, insert the new element connectors, and push the wire back into wall then fasten the element with 2 screws.
After turning off the breaker to cut power to the oven, I opened the oven door and, using the PartSelect exploded diagram as a guide, I removed 3 screws from the underside of the control panel - I was then able to slide the panel up and out to remove it. Leaving all of the control wires (especially the ribbon) connected to control panel, I saw the fan assembly mounted to the rear of the control box.
I noted the position of the two attached wires - black on top (or left), white on bottom (or right). Using a nutdriver with an extension bar, I unscrewed 4 screws holding the assembly in place. I removed the old fan and installed the new fan in its place. It was necessary to bend the new fan's legs out a bit to get them to line up with the holes. I reconnected the wires as mentioned above, then reinstalled the control panel.
I tested the oven by turning the breaker back on and letting the oven heat up to 450 degrees. The fan turned on as expected. After the oven cooled off, I reinstalled the 3 screws to secure the control panel.
