To begin with, I am a man married to a woman with a 2year old daughter, i say this because it is pertinent to the story. The fridge in question makes a noise to which I cannot hear. My wife hears it, and my daughter plays with her ears when my wife can hear the noise. if the fridge doors are opened the noise changes but could just be tenitis that was caused by the original noise and the noise could have ceased. shifting the fridge, i am told, causes the noise to change to a bearable tone or to go away. My thoughts are the circulation fan motor. Thought I would ask the masses and get a second opinion
