Product review (3 stars): Great part, poor instructions for newer model dryers
We purchased this to convert our new Whirlpool gas dryer (Model WGD4800BQ) to use liquid propane (LP Gas).  I would give the conversion kit itself 5 stars and the instructions 0 stars.  If you have an older dryer, the instructions probably get you through the conversion just fine; however, the instructions have not been updated for newer dryers which do not require (nor even have a place for) the blocking pin. After my husband pried the screw regulator cap off attempting to locate where to put the pin on our dryer and discovered that the pin still didn't fit, we got online to figure out where we went wrong.  We found instructions for another part at http://www.scribd.com/doc/33181900/Whirlpool-Gas-Dryer-Conversion-Kit-Instructions-W10301479A#scribd, and those got us through it.  The article explains that there are two different types of gas valves, "Style A" and "Style B" and shows you pictures of both.  Armed with this information, the conversion was a piece of cake and only required one of the three parts that come in this kit and a simple turn of the "Style B" dial from "NG" to "LPG".  However, when my husband pried off the screw regulator cap, it stripped the threads, so we had to go to the Whirlpool site and order a new one at a cost of $15.88 (including shipping).  Hopefully, my review will spare others some grief, and/or the seller will see it and update the instructions.
