Product review (1 stars): Loud, low frequency droning noise from the refrigerator
Refrigerator had a loud, low frequency, droning noise after a couple of days.  3 service calls later, problem identified from a GE service bulletin as a compressor noise issue.  Service tech had to order a "stop compressor noise" kit and install the parts.  GE knew about the problem and did not fix the problem in the manufacturing process.  According to the service tech, since my refrigerator was built in December 2014, it should not have been part of the service bulletin, except my compressor had a serial number matching the ones in the service bulletin.  Obviously GE continued to install these compressors on the latest built refrigerators and will have to use the retrofit kit to silence the droning noise.  Do not let GE tell you this is "normal" noise from the refrigerator.  It is not, and it can be reduced significantly.
