Product review (5 stars): Only took three hours and two years
I just finished installing this kit in my Kenmore refrigerator, so let me tell you how it went.

First, I found a video on YouTube that showed how to replace the ice door--it is currently posted by AppliancePartsPro. It was quite helpful--up to a point.

The video shows how to replace the door, but the kit comes with the door, door mounting bracket, spring, and dashpot (that's the black cylindrical thing). I was VERY glad I had the full kit because the white plastic bracket on which the door mounts was broken, which is why my door didn't seal correctly.

The video makes it look like a 20 minute job, which it probably is on a new refrigerator. However, as others have noted, the hardest part is to remove the front plate without breaking it. I wish I could give tips on how to do it, but just use a putty knife and/or slot screwdriver on the bottom of the panel (look for the two slots) and take your time. I spent an hour on that part (well, part of the time was searching the Internet for clues on how to remove it--there aren't any). But if your refrigerator has been in use for a decade or two, the front panel will adhere and be difficult to remove.

You can take pictures as you go, or refer back to the YouTube video.

The new dashpot (the black cylinder) seems to work a little differently than the old one, or maybe the old one was worn out. It slows the closure of the ice door, giving time for the ice to fall through, and then snaps shut. I like it. Google "dashpot"; I assume Wikipedia has a good description.

So it only took two years and 3 hours for me to replace it (my wife asked me for two years to do something about it).

So now my next job it to fix the leaking Kohler Avatar faucet I bought some years ago. I'll let you all know how it goes.
