Product review (3 stars): Replace the fan
My family has had three of these.  One failed after a year and was sent back.  Ours failed after two years. It was the condenser fan.
replaced it and works fine.  Daughters same thing.  A new fan and works fine.  As all refrigerators you must clean the condensor fins when dust builds up.  I open them up and use compressed air.  Looks like company got a bad batch of fans.
