We began to hear a grinding hum coming from the fridge. Never having worked on a fridge before, I decided to see if the problem was something obvious that I could fix. I removed the engine cover and immediately found the source of the noise. I went to appliancepartspros.com, entered the model number of my fridge, and did some research. I found the part I needed and ordered it. It arrived 2 days later on a Saturday. I then watched the installation video and installed the part in about 30 minutes. Problem solved! Our fridge is now quiet again.
I did not get an estimate on this repair but I did check the price of the part with a "brick and mortar " store and appliancepartspros.com saved me $40 on the part alone. I estimate a service call would have cost me in the neighborhood of $200-250 when you add labor, trip costs, etc, not to mention having coordinate schedules to be home to meet the repairman.
Applicancepartspros.com is the way to go! My only advice would be to do your research and be safe by knowing your DIY limits. This was a simple repair that saved me time and money!
