Product review (5 stars): Money Saver
I paid $200 each time to have my fan motor replaced 3 times.  It was easy to see the fan motor and noticed that it was snapped into place.  I thought for under $50 I could replace this myself.  It took me 20 minutes to replace, and it was a pain to get the old one out and snap the new one in but I did it.  If you have patience and some mechanical aptitude you should be able to do this yourself.
While I was waiting for my new motor I bought a cheap fan at Walmart and placed it behind the refriderator to keep the condensor cool and it worked fine.  Try that at your own risk, but I did not have any problems.
