Actual R & R was slightly different than the video. The only screws were on the back of the dryer. there were no screws on the front or back of the timer and the timer had no screws. You needed to push and turn the timer to "snap" in place. There were three metal wires, well identified that came apart from the old unit and inserted in the new one. Instead of a plastic case on the bottom that the video said needed to be removed with a small screw driver; there were another set of wires that needed to be removed from the old unit and inserted into the new one. It took about an hour, but that included clean up of the exhaust piping and the dryer area that only gets cleaned when work is done on either the washer or dryer. And it works perfectly! Saved $90 on a service call.
