Chinook RV

Hi, I bought a 2000 Chinook Concourse a week ago. The fridge was working great for days, until I parked on a steep hill and forgot to turn off the propane, I think this is when it stopped working. I can feel some coldness in the freezer but it never gets to temp. I have been plugged in for 6 hours and still the fridge is not cold running off AC.

Where do I start to diagnose my issues?

Someone else may reply with something more helpful.. But it order sound good. The steep angle can cause something to crack and basically ruin the fridge (at lest.. That's what I've read).
It stays on and doesn't go to "error" or anything on the light indicators?

No the check light does not turn on. It turned on after the night on the hill. But nothing now, just normal lights.
