Adjusting gas pressure

I have had an issue with my refrigerator not cooling well on gas while underway. I start out at 33 degrees and it heats up to 58 or so on a 80 degree day. After a little research i thought I should start by checking the regulator pressure and after building a Manometer using this nice description and testing procedure on this site RV U Tube Manometer
I found that the pressure was set too high at 18 inches with the refer, water heater and furnace running. I turned it down to 11 inches with all running. I did notice that the water heater, stove, furnace all have their own regulator but the refer does not.
Not sure if this will solve the problem but I can only assume the burner flame wasn't working efficiently at higher pressure.
Anyone have the same problem?

Thanks,
Phil

If all is well when you are parked, sounds to me like maybe the air flow up behind the refer may not be right for some reason when you are under way. Or the flame is not heating the chimney when you are under way.

I think that Jim may be onto something here -- I don't think it is the LP pressure, as the flame is nothing more than a pilot light (well sort of). You could easily retrofit a shroud around the flame / chimney to make sure you are adequately heating the chimney while driving.

Not sure I am interpreting your original post correctly -- do you get 33 degrees from the gas while parked -- or is this from the AC power?
