I recruited my nephew to help me put it in. He had worked with a local school system in their maintenance department and his knowledge was a huge benefit. We both pulled the casing out of the refrigerator that contained the PC Board. Replaced the old board with the new board and so far is working just fine. What was amazing and sad about this repair is that I had called a reputable service company out and both techs insisted that they could not find the part. That part was not being manufactured anymore. They tried to sell me an in home warranty choice program for $599 not once but several times. They even told me they could get me a discount on a new refrigerator of my choice and, that they would be willing to take the old one off my hands if I paid them $50. That is when I went to the internet and found AppliancePartsPros.com and went through their suggestions on what may be wrong with my refrigerator. Their information was spot on and it is running fine. Thanks for the information or otherwise we would not have known what to look for and, I would have ended up with a new refrigerator when I did not need one.
