Shore power or propane?
I'm guessing you have now pushed the little button that turns your fridge on "automatic" and it is now either cooling on electric or propane???? It takes a while, be patient. I hope it is as simple as "The little button" not being depressed. If you are now on electric a blue light should signal your fridge is cooling. If you are not on shore power and on propane, go outside, open the inspection door and take a look to make sure the "propane flame is ignited.
