After a few internet searches, I determined the frig outage was due to a failed main control board. I was able to find a compatible part from AppliancePartsPros.com. I confirmed the part was for my frig and in stock via their online chat portal. I ordered the part on a Saturday night and it arrived on Wednesday via their standard shipping option. I reviewed videos online on how to take out the old board and install the new board. I then found instructions online on how to reprogram the board from my frig model. After reprogramming, the firg was back in operation as if new and 3 days later so far so good.
