I had friends that took it apart and found that the motherboard needed replacing. We googled the make and model number and found the replacement part. Ordered the part, and when it came in, replaced the part. Working like a charm. I was so afraid that I was going to have to replace the refrigerator. We had just come through hurricane Matthew. I knew it was something to do with the power surges during that time. I had lost power for 5 days during the storm.
