Product review (4 stars): Why didn't they include this with the dryer?
Product works well  but I do believe that whirlpool should include this with their high end dryers. It probably costs them 4 dollars in parts/material and they charge between 15 and 20 for this kit. It does take about 45 minutes to reverse the swing of the dryer door. You are basically disassembling the door in order to reverse it. The only real useful part in this kit is the large plastic piece that covers the gap where the hinge once was before you reverse the door. The other 2 parts in this kit are to cover the screw holes on the dryer itself and a rubber piece to go behind the chrome part of the door to function as a cushion when you place your fingers in the opening to pull the door open. Like other reviewers stated, take pics of the door before you take it apart. It will help you in the long run. Good luck!
