I watched the video on how to replace the part. With the new part laying next to the old one (which was still on the dryer), I changed each wire one at a time. Then I locked it in place on the back panel. No screws to hold it, it twists and locks really easy. The I put the back panel back on (after using a magnet to get the two screws I dropped!) This job is fairly easy for someone who uses tools regularly. The hard part would have been knowing what part was bad if it had not been for the timer not turning easily.
