Product review (5 stars): Yes - you can do it yourself.
This is the stuff. Our dryer died and I wasn't ready to buy a new one. Did a little trouble shooting to determine that everything else worked correctly, then surfed the web and was saved by a YouTube posting. Here's the link to the video I used: https://www.youtube.com/watch?v=D5LUPxmWpG4
Not plugging anything, just found their video very helpful and thought out, so you know what to expect before you start.
