Product review (4 stars): OK dryer door reversal kit
I bought the dryer door reversal kit used.  It was in a sealed bag, accessories and instructions included.  It took me about an hour to do the project since you have to completely disassemble and re-assemble the door. I only had trouble putting the door handle area back together.  The instructions and illustrations are basic and leave a few questions unanswered. Some screws just turned in their holes, not grabbing anything on the other side even before taking the door all the way apart.  I installed the kit and it works fine.  The handle part is still off kilter,but the door works fine.  On the funny side, I did end up with 2 extra screws--must have been from the inside--and when I picked the door up to install it, another screw fell out.  I'm not concerned as I am sure the door is solidly put together and works well.
