Refrigerator won't cool down

We bought this travel trailer about a month ago, this weekend was to be our first trip trying it out. It's a Crossroads Slingshot 23CK and has a refrigerator with a separate freezer door. It was working great up until last week. I had unplugged from the house and then plugged it in last night and now it doesn't work. The battery had been a little bit low so I disconnected everything and hooked up my regular automotive battery charger to the deep cycle until it was charged using the two amp setting.

Here's where I'm at:
The battery is fully charged up, connected, and the camper is plugged in to our power in the garage. All the lights and the power and the air conditioning in the camper work great, except the refrigerator will not seem to cool down. The light inside turns on when you open the door, and I think I have the switches on top of the refrigerator in the correct positions. First button is pushed in so the refrigerator is turned On and the second button's pushed in so that the refrigerator is in Auto - not gas.

The camper is perfectly level, I have two full bottles of propane, and they are connected but both valve turned off. Am I missing something???
