I clean our fridge on a regular basis, but noticed that it was louder when it was running. I pulled the fridge out when it was running and was pretty confident that it was the compressor motor, but to be sure, I unplugged the fridge, then disconnected the compressor motor and plugged the fridge back in to narrow the noise down to this, which it was. I researched the parts online and found this site had the best deal. When the parts arrived, it took me less than 30 mins to replace the motor and it fixed the problem. It is located in a tight space so takes a little longer, but overall it was an easy fix for a reasonable price.
