I did an online search for 'noisy refrigerator' including the make and model number. Your website had a list of the most probable causes. After viewing the videos, I checked out the Motor Cond Fan. The fan blade did not turn freely. It was very sluggish. I ordered the part from AppliancePartsPros.com and the motor was delivered within 24 hours. I installed it using the video as my guide again. The noise is gone! I believe that motor was about to go out completely, and who knows what damage it would have done to the remaining component parts.
Also, the week before I fixed the refrigerator, I ordered parts from your company for my noisy dryer. Again I used the online video to diagnose and fix the problem. The parts also arrived within 24 hours of ordering online. Such a relief to get rid of that racket! Next time I won't wait so long to fix a noisemaker appliance.
I might add that I am a 66 year-old woman with no prior experience fixing appliances.
