Product review (4 stars): Works, installation takes a little time.
I bought this to convert our new LG DLG3051W dryer to run on propane.  The instructions that come with the part are for another model washer that isn't very similar.  It would be nice if the included instructions covered a few different LG dryer models.  For the DLG3051W (completely flat top), it wasn't too bad to get apart.  Remove three screws on the backside and slide the entire metal top cover off.  A few screws and plastic clips and the front panel come off (I laid it on the top of the dryer).  For the front of the washer (including the door) there are some screws along the front, but you also need to take off two screws near the lint filter.  I believe there were some clips also.

From there, replacing the orifice and screwing down the mixture screw is fairly easy and matches the instructions included with the part.  I saw a youtube video where they went didn't take apart the dryer, but instead reached through the exhaust to get to the orifice.  On the DLG3051W, I don't recommend doing it this way.  It would be very difficult to screw in the new orifice without having a clear view of it.  The 30-40 minutes it takes to pull the dryer apart is worth it.  Putting it back together takes five minutes.  The dryer works fine with this part installed.
