Have same fridge in 19RBPR, and had some issues in first year. If the unit is not level front to back, it will not cool.
Does it work on AC?
Does it work on DC?
Are you in Manual Mode or Auto Mode?

I did have a sensor replaced for the propane function and never had an issue again. I always switch over to propane manually before unplugging, and I always power off before plugging into AC before turning onto Auto. I just don't trust the computer board to know what's going on.
