I don't get what your issue is. From the pictures, the check light is on. What are you trying to do? Is the camper plugged in and your operating on electricity?
Or - are you trying to run on gas after an extended period being in the off position? If the later, then most likely, air is in the gas lines and needs to be purged by turning on the stove and igniting until you get solid flames on all burners. Then try the fridge. And as stated, give it a while to cool down once the check light is not longer flashing. If the blades inside the fridge feel cool, then time is most likely all you need.
You want to operate it in Auto mode which means the fridge operates on electricity if available, otherwise it switches to gas.
