Replaced the heating element in the bottom and also replaced the temperature sensor. I removed the door first to get it out of the way. I pulled the oven from the wall and unplugged it. Then I took out the screws holding the element and sensor inside the oven. Then I removed the metal plate covering the wires on the back of the oven. From there I could disconnect the wires for the element and sensor easily. Removed old parts. Installed new parts, back cover, and door. This fix was easy, but decided to spend a lot more time deep cleaning the over and stove while I had the door off. Tested with a thermometer that hangs from oven rack to see if it was coming up to temperature.
