I have a Kitchen Aid side by side refrigerator/freezer which is 8 years old. One day it just stopped cooling. At first I was just going to junk it and purchase a new one. However, I took off the lower back cover and noticed the compressor was not running. I knew from experience that these compressors need a starter capacitor and relay and it is not uncommon for these parts to fail. I looked on the Internet for a video which showed how to remove the parts. I also found a video which showed how to test the compressor. After removing the capacitor and relay it was obvious the relay had burned out. Since the compressor checked I purchased a new capacitor and starter relay for under $60. Now the refrigerator cools better than ever.
