Product review (5 stars): Built in diagnostics said evap fan too slow.  Perfect OEM replacement.  Saved my high $ refrigerator from the junk yard (yea!!)
My built in, cabinet depth, 42" side by side refrigerator wasn't cooling well.  Called an appliance repair man. $100 service call,  Told me it was a freon  leak.  Thought of just replacing the unit but then decided I should take a closer look.  Quick internet search, found the repair manual, ran the built in diagnostics.  This told me the evaporator fan was running slow.  Bought this part, seems like a perfect OEM replacement.  The install was easy.  Best of all, the unit is working like a charm.  Sometimes it is just best to take responsibility for your own technology.  Not really that hard with the internet at our fingertips.
