I wonder if your fridge requires a lot more time and attempts to clear the repeated fault code. I say this because when I awake our fridge after a long period of no-use, I first have to get the stove burning gas well, then when starting up the fridge, it goes through a number of attempts with faults before what I think is a consistent flow of gas that gets it going and keeps it going.
Our fridge is not inside a slide-out. I understand that when the fridge "IS" inside a slide-out, it can sometimes be even more finicky because of the long flexible gas line along with the side-discharge exhaust out the wall rather than through the roof. It may be worth a call to Kermit. The 2010 model year you own was the first year of the fridge included inside the slide-out for models 2350 and 2551. Phoenix might have learned something that first year and modified their installation to address the problem.
Now that I think about it more, I seem to recall others with a similar problem back when the 2010 was introduced. Call Kermit.
