My unit isn't hard wired in, but plugged in under the sink. I unplugged, and removed the bottom panel (4 phillips screws) and the inside panel of the door (7 Torx screws). I didn't have my Torx set, but used a suitable allen wrench with no problem. The door wants to close due to a spring, so I held the door open with some tools for counter weight. There are 4 wires to pull from the inside door panel to allow the panel to be completely set aside. As a general rule, I use my camera phone to take pictures of wiring the I'll be pulling, and the general area I'm working on. It's too easy to "not notice" something and wonder how to get it back together properly. I noticed the foam insulation strip was in bad shape on the left side. There is a plastic covering of this strip that helps form the seal when the door is closed. That was intact, but the foam behind it was wet and didn't have enough integrity to stay tight against the opposing plastic. After the new strip arrived, I repeated the above steps for the repair. The existing strip was a little tough to remove, since the adhesive strip was old and tore easily. I used a small putty knife to work the strip loose as I pulled it. Once removed, I installed the new strip by peeling back part of the protective cover to insert the strip into place. There is a small metal tab that the strip goes under on the right side. It is very difficult to insert a sticky piece of foam into a tight spot without it sticking on everything as you insert it. To avoid the sticking, I pulled back some of the protective cover and attached the strip a couple inches back from the edge, leaving the right amount of strip "folded back". This way, I could have the strip attached in the proper position,then fold the end piece into place under the metal tab. It was easier to deal with the sticky foam this way, rather than trying to force it into place. From there, I peeled the protective coating a few inches at a time while pressing the foam into place. Easily reassembled and tested! HOWEVER, it appeared that the old seal was actually ruined by the door gasket leaking on the foam from above. I found this problem AFTER replacing the foam seal. When pulling it apart again, I found that the new foam was wet, but the plastic seal on the front was not (it was before, since the foam behind the old one was too soft to seal). The door gasket is on order now, and is said to simply slip in the slot of the old seal. In short, you may need to order both seals. Check for moisture on the left lower door to see if water is getting past your upper seal and order both parts if needed. Part numbers: Foam seal (foam insulation strip): WPW10117748.
