Ronald B Henderson , KY January 11, 2016 Vent louver was cracked and broken as well as the handle Replaced vent louver by removing old one and installing new one by snapping it into place. The handle I removed two screws on side of door with a Phillips screw driver and the with a straight screw driver pried off outer track then removed handle screws under the insulation strip with a Phillips screwdriver. I then installed the new handle and reassembled the door in reverse fashion. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
