Product review (3 stars): Easy To Change Out - Instructions Lousy
It was easy to change out once I found a video online and basically took my dryer apart. Taking the dryer apart was a pain, but the actual installation is easy. The instructions included were lousy at best. There are two versions you can use to convert it.

I used the one it led me to believe I needed. When we put it back together and turned it on it sounded like a rocket was about to launch. My guess is the oxygen/fuel mix was too rich. I'm not sure if changing it to the version would have worked, but instead of taking a chance we ended up just buying a new dryer.
