An RV refrigerator uses 12V-dc power for it's control circuits no matter what power it is using to supply the heat for the coolant system. It is that use of 12V power which allows it to shift from one source to another.

The symptoms that you have clearly indicate that you are loosing 12V power to the refrigerator when you unhook the shore power plug. The first thing that I would do is to unplug the cord and then check to see if you interior lights still work. If they do not, that then tells us for sure that there is no 12V to anything, and not just to the refrigerator. Once we know that, it will mean trouble shooting to see why you are loosing 12V power when you disconnect.

Very likely it is a battery related problem since you clearly do have 12V from the converter with shore power.
