I pulled the stove out from the wall so I could reach and disconnect the power cord. Then I removed the oven racks and the back panel to make it easier to disconnect the element from the wiring, removed the two screws holding the element in place inside the oven, inserted the new element, attached the wiring cleaned the accumulation of spillage from the past 20 years, re-connected the power, replaced the racks and the back panel, re-connected the power, and moved the stove back into place. It was not really necessary to remove the back panel.
