Product review (5 stars): Fits Perfectly and Correct Replacement for Samsung RS2630SH
This fan assembly was for my Samsung RS2630SH Side by Side Refrigerator-Freezer.  The old unit had begun to squeal every time it would come on so needed to be replaced.  Removal and installation was very easy with the time from when I rolled the refrigerator out to the time I pushed it back in place about 10 minutes.  The only tool I needed was a screwdriver to take the panel off of the back of the refrigerator.  A few installation comments:

1) Unplug the refrigerator.

2) You may not need to purchase the fan itself.  I did not purchase the fan blade.  My fan blade sits on top of the spindle and has a compression-like design in which the spindle is inserted to the fan.  It is kept in place with a small wound coil that compresses the center of the fan to the end of the spindle.  The coil is easily remove with your finger and easily put in place by pushing it back down over the spindle.  No tools required for this part of the operation.

3) There are tabs at the bottom of the fan that slide under a lip on the white, plastic mounting bracket between the cooling coils and the condenser that hold it in place.
