I used your video to disassemble the dryer.
Overall it was pretty easy. I used a power screwdriver which made the job quicker.
Only con was the video;I know it is impossible (due to cost) to make a video for every model.
The beginning of the video was completely different on my model; the top cover can not be completely removed. You have to hang it over the back of the dryer. Once you get pass top/cover the video is very helpful. It took me about 3 hours to complete the repair; that includes pulling out the dryer, cleaning it, repairing it,and putting the dryer back in to the space.
