Product review (4 stars): It Wasn't the Correct Replacement
I punched in the part number from my old icemaker in the search box at amazon.com.  It came up with this item as the replacement.  It arrived well packaged and on-time, but it wasn't the same thing.  I have a 5-cube icemaker that looks very similar, but is narrower.  It looked close enough that I didn't notice the difference until it wouldn't fit in the freezer.

I was able to take the motor from the new one and swap it with the motor on the old icemaker.  I removed 4 screws on the side, and all the electrical parts and the small gearbox were easily swapped.  The motor and everything appeared to be exactly the same.  It worked!

Also, the correct, 5-cube icemaker was available from amazon.com, but it cost about $5 more.  This actually worked out well, because I got it fixed, and it cost less.  The big question is why does the 7-cube icemaker cost less than the 5-cube model?
