Do-It-Yourself Story

Unplug oven from power supply. Unscrewed 2 screws from inside back of oven (these were corroded a bit and difficult to remove). Separated the element from the wires using a wiggling up and down and side to side movement (you can't just pull straight out). Fit the new element into the wires and recreated to the back of the oven. Slipped the top support brackets into place and done. Took about 40 minutes only because of the difficulties with the screws and wires.
