Cooling to 40 degrees is pretty good if measured like I described. Does it hold
this temp for several hours during a warm day? Cleaning the burner and flue vents
is helpful if the fridge won't light or goes out often. It won't really help
cooling performance much. Cooling is dependent on how much propane is burned, the
sealing of the fridge door, and the fan behind the fridge operating correctly with
clear cooling vent areas. The pressure regulator should be set to about 10 inches
of water to supply the maximum propane without causing the flame to go out due to
insufficient oxygen coming in the flue intake. If the flame won't stay lit at 10
inches of pressure, cleaning the flue vents is needed. Setting the pressure above
10 approaches the limit of the flue air supply intake and increases the likelihood
that the flame will sometimes go out during the night. Higher elevation camping
means less oxygen in the air, so higher propane pressures can not be supported by
the flow capacity of the flue intake system. The fridge will cool better but only
until  the flame goes out. Setting the pressure to less than 10 may be needed at
higher elevations. I live and camp at sea level so I don't have real data on
pressure vs  performance at higher elevations. I would like to get propane
pressure feedback for 5,000 and 10,000 feet if anyone has measured values over
multi day camp stays at these levels.
