Product review (4 stars): Most Energy Efficient Refrigerator Ever Owned.
This unit is the most energy efficient refrigerator we've ever owned.  We have the capability of keeping track of how much power our whole house uses daily--by going to the power company's website.  When we go on vacation (and of course the refrigerator continues to run all the time we are gone) the total KW's used by the entire house per day is less than 4 KW/day.  The only complaint I have is that on the outside of one corner of the ice-maker, way in the back of the unit, frost always builds up on the outside of the ice-maker in that one spot.  So periodically I have to go in and break that frost build-up off with a table knife.  Other than that we have had very few issues--other than having to replace a couple of LED lights on the control panel. It is a very quiet running unit except when the compressor operates--which is only for a couple minutes every hour.  There are other circulating fans that run almost continuously (which you would think would take more electricity, but they don't) and they aren't annoying to listen to.
