Simple fix really. We had a water leak from the door gasket. Toughest part of the entire procedure was cleaning the water impurities that had built up from around the perimeter of the channel where the gasket sits in. Water/vinegar mixture, kitchen towel, and a flat head screwdriver, combined with some elbow grease got it all cleaned up. Then it was just a matter of inserting the gasket into it's channel starting at the top middle, then pushing it in around both sides. Took about 45 minutes to an hour to clean the channel completely so the gasket would seat properly when inserted, and then probably a minute and a half to install the gasket.
