Product review (3 stars): Somewhat noisy, energy efficient
Updated info (2 years later):  unit has become less noisy over time, even though the variety of clicks, pops, etc. has increased.  Unit is VERY energy efficient - power bill decreased significantly after installing this fridge. Changing from one star to three.

Unbearably LOUD.  Just had this unit delivered this morning.  It sounds like a vacuum cleaner is running.  And, the loud compressor keeps running for 45 minutes at a time, even though I don't open the door all day.  GE support claims the sound level is to be expected with energy efficient appliances like this one.  It's hard to believe this will be an energy saver.  Returning/replacing a refrigerator is a huge hassle, but I have no choice.  I'd review other features of this appliance if I considered it to be at all usable, given the noise problem.
