Product review (5 stars): Fits Great - Installation is Tedious!
Fits my Kenmore Model 10659589990 perfectly! I watched the installation video on YouTube from Appliance Pros (Refrigerator Ice Dispenser Chute Door (part #WP2180353)-How To Replace). It probably took me 45 minutes start to finish, hardest part for sure was getting the front panel off. Mine didn't come off as easy as the one in the video (of course) and it feels like the thing is going to snap in half - so - realize you will likely need to use a lot of pressure. Same thing putting that front panel back on, I basically wacked both bottom tabs super hard to get it back on.

That all being said, I almost bought the entire ice door replacement kit for $38 but read some reviews on that product that said it was likely just the door seal causing all the frost in the chute and in the ice maker "wheel". Sure enough that's exactly what our problem was, the old design has this foamy stuff on the inside that wears out. This new door doesn't need the "heater" line going to it (just disconnect it) as this material apparently doesn't freeze like the old. Hopefully it will hold up.
