I had to go w/this model/cu.ft. because of space in kitchen.  Although Owner's Guide only references "Normal operating sounds", when the frig does "Hummm", I think it's too loud & disrupting. Also, when closing the refrigerator door, it suctions so much, it makes the freezer door pop a bit and pushes the frig towards back wall. I put a 2X4 behind it so my magnetic paper towel holder doesn't get pushed towards the front & fall off! Even w/the board, then the frig goes crooked into the space cuz I have at least 3 open inches on both sides. I usually don't complain when I should be happy w/what I have but these issues are something other customer's should take into consideration.
