Hi Caaaaarrrrrll.
Thank you for bringing this to our attention. I see you have some concerns with the 33 in. 21 cu. ft. Top Freezer Refrigerator with FlexZone and Ice Maker in Fingerprint-Resistant Stainless Steel having a buzzing nnoise. I sincerely apologize for the inconvenience this has caused you. Please know that we value your feedback. We will continue working on improving the quality of the products we offer.
These sounds also describe the sound of the compressor. It sounds just like a quiet engine or motor. It will start up, run at low or high speed (and can change speeds), might make some clicking as it operates, and maybe sputters a bit as the fan slows to a stop.
Here are some links for more details to help you maximize the appliance's potential.
