If you have to put the trailer at an angle for a sustained time. You have to turn the fridge off. Don't rely on unplugging the trailer. Until you hit the off button it's trying to run. My fridge was on propane. I assume the OP was as well since he was changing a tire on the road. When off kilter the propane system has a check valve that will shut off the propane. Fridge is still running but has no power source(propane or electric) for the coolant. Display panel works off 12v battery on my fridge. It keeps trying to restart. Sensors tell it something is wrong and kills the cooling. Once level propane will start flowing again but the fridge electronics must be reset. Dealing with ammonia as the coolant, this not your kitchen fridge. Ammonia is very dangerous when not properly contained. Lots,of,safe guards in the system. I wish I could tell you the sequence but I'm in a phone and Bryant RV won't let my phone's browser on their website. This is a time thing as well, the trailer can go off kilter and keep running as long as it comes back within a certain time frame. You can learn a lot more about how these fridges work by reading the service manual Bryant has posted. Owners manual don't have much detailed info. I printed my model's and keep it in my trailer for future use.
