Old element burned out

Turned off the power to the oven. Removed the racks. Removed two screws holding the unit to the back of the oven. Removed two screws holding the wires to the terminals. Removed the old unit. Reversed the process. Piece of cake. The only "difficulty" was that the old wire-to-terminal screws required a nut driver (as did the unit-mounting screws) while the new wire-mounting screws required a #2 Phillips screw driver. Took me a couple of minutes to get one of those from the garage.
