I would pull the fridge and check the entire burner, flue even the roof vent for anything that might be a problem with the flow of the heat from the burner. I'm trying to remember what the burner assembly looked like when I replaced my fridge. As I recall the electric element was up against to the tubing for direct heat conduction (or at least very close) while the propane flame had more of an air gap and was dependant on convection and good air flow with the heat rising thru the burner assembly and flue for transfer to the cooling unit. Either way if there is a cooling unit problem you'll need to pull the fridge to replace.

I made a stand that I could lift with a transmission jack to get the old fridge out and the new in. Made it real easy. Disconnected the propane line, unplugged electric and about six or eight screws and the fridge came out. Unfortunately I don't have any images of the old fridge but you can access every inch of the cooling unit other than the few sections that are buried in insulation. This will also give you full access to the burner and flue so you can do a detailed check. It could be something as simple as a piece of fiberglass insulation is blocking the heat from rising thru the flue/roof vent and you can't see it from the maintenance panel.

You could also put together the right pipe fittings, tubing and a low pressure regulator for full up test on propane with the fridge out of the alcove. Just incase I would also get the fridge out of the coach before attempting. Although the risk is small working with sub 1 psi propane it's still a risk in a close space such as a class A.
