I'm a woman in my late 60's. I do all of the handy person chores in my house. I replaced both top and bottom heating elements in the top oven. I removed the oven door for easy access. I just had to unscrew the elements from the back; unclipped the wire heads from the elements. (Keeping the wires clipped with paper clamps so they wouldn't retract.) I then removed the old elements and replaced them with the new ones. Pretty easy. Thank you for sending them fast!
