Replaced the main control board. Contemplated buying a new refrigerator as it is 10 years old. I called the help line and described the problem. They told me the part I needed and if it didn't fix the problem I could return it for a full refund. The part arrived in less than 2 days. The video on the web site guided me through the installation process. Removing the old one was a bit more challenging than the video portrayed, but with some patience and persistence it was able to remove it. It took me about 20 minutes to replace the part and it is working perfectly.
I highly recommend appliancepartpros.com!
