should just be a/c. but just make sure propane tanks are closed. unless you are using the grille or furnace. btw what model pup do you have that way if someone has that model they might be able to help more. mine is a hw276 3way fridge so mine is automatic.
Mine had controls on the front for selecting. It also has an auto feature where the default will be AC, then propane, then DC. I would think you should at least have a manual switch.
Why? I open my valves when I arrive at the campground. If I'm running the fridge on propane, I ignite the propane system, if not, I still open the valves for heat if it will be needed later in the night.

Interesting. Mine is all manual, requiring me to switch to whatever mode I want.

My Flagstaff 227 popup is automatic to electric so I have to manually choose propane by lighting the pilot. I found out from my neighbor that while the fridge is on electric it does not get as cold as when on propane. My last trip I actually had a little ice in my sodas with it on propane.
My controls are in the inside panel on the outside of the trailer, it has 1 thru 9 marked with 9 the coldest
I had a friend who is a veteran RV'er tell me that he runs his refridge on dc while traveling then cools it with propane before going to ac. He says propane cools much faster.
Fridges usually have to be switched from one power source to another. Propane refrigeration usually needs to be lit to work. Our fridge when switched to 12v only maintains a cool temp... not as cold as when on 110v or propane.
