I pulled down the wire around the glass cover. . . Released on end of the wire from its holder being careful to not let the glass cover drop. Unscrewed the bulb and replaced with replacement. Easy, easy.
We turned off the power to the oven and removed the oven racks. Then we used a screwdriver to remove the metal plate in the back of the oven which held the connection for the old heating element. The element pulled out easily and then we connected the wires to the new element. Very simple.
Took off the oven door, oven in wall mount, had to pull oven 80% out to access both end of spring holders, reattached springs, slide oven back into place, installed face-plate and oven door. The most difficult part was pulling oven out of wall, I did not know it would be that heavy.
