PO began showing up with the bells of an open door and repeated about every 15 minutes. The freezer started thawing slowly and stopped making ice. The refrigerator appeared normal. After some web searches learned that the control board was most likely the culprit (it was). With just a 1/4 socket and a flat head screw driver, was able to remove and replace the control board. Here is a 1 minute video of the operation.
Safety note: If your not aware that you should unplug the electricity well before you start, this project might not be for you.
