I determined that this was the part to get based on a previous reviewer's post who had a similar problem. I bought the controller, it shipped quickly and I received it two business days later. I followed the instructions of the previous poster and had the device installed in about an hour. The most difficult part or should I say tedious part was unscrewing and then replacing the panel and screwing everything back in. The refrigerator keeps temperature now and turns on periodically as it should.
