Product review (5 stars): Cheers to Cold Beer!
This was an exact replacement for the fan motor in my fridge, and it has been working great for a month or so now.  This is an easy do-it-yourself fix.  The hardest part was diagnosing what was wrong.  My old fan was running, but running to slowly and was silent.  The new fan can be heard pushing air as expected.  Aside from the old fan being quiet, the other symptom was the refrigerator compartment being too warm, even though the freezer was (usually) frozen.
