Product review (5 stars): Propane conversion kit
This is somewhat time-consuming to install. If you are mechanically inclined and have a few tools you will save about $100 to do this yourself. I put this in my new Whirlpool Duet dryer and it works fantastic. It took me about 40 minutes to complete the job. There are many YouTube videos on how to do this project.  I suggest you look at them before you try it yourself.
