I moved the oven out from the wall and unplugged it. I unscrewed the back top panel. I took a picture of the wire connections. I removed the dial at the front of the oven. I removed the 2 screws that hold the Regulator in place. I changed out the wiring one at a time to the new Regulator. Reinserted back into position and attached with the screws and replaced dial. Plugged back into outlet and tested.
