Product review (4 stars): When the noise would start the fan would slow down considerably so the fan was going bad. Did a parts search online and came up
The old KitchenAid refrigerator in our garage had been making noise periodically for 2 years.  This is the old style refrigerator with the freezer door above and refrig below - very basic.  Well if finally got to the point that the noise would last longer than several minutes and became almost constant.  I thought the refrigerator was dying until I did some googling and tracked the noise down to the freezer compartment.  Sure enough, the noise was coming from the freezer.  Watched a couple of youtube videos and took the freezer apart to where I could see the fan.  When the noise would start the fan would slow down considerably so the fan was going bad.  Did a parts search online and came up with this part.  Once the racks, ice maker, and backwall were off, the fan/motor came off as a single unit.  Install was just the reverse.  The only gripe I have is that the mounting screws that came with this were thicker than the ones that came from factory.  The old plastic studs didn't like the new screws and one of the split.  I was able to remedy by wrapping some zip ties around the stud and so far it has held and fan is working perfectly.  Also, the wire connections this were not exactly the same as the original unit so I had to strip back the pigtail in the freezer and reroute the wires so fan blade did not his them while spinning but that wasn't really a big deal.  Bottom line is it worked, saved me 1/3 of what I would have paid, and saved me buying a new refrigerator/freezer!!
