With greatest respect, you are correct that the method for cooling is the same; Heat, from whichever source, "boils" the ammonia in the reservoir when cooling is needed.
Just saying, like heat from an electric range vs a gas range, the gas flame will get get the water in the pan to boiling quicker than the electric element on High. The water will not care as it boils at 212 degrees F; just it will reach it faster on gas.
In this case, if the available heat from the propane is being diverted (or corrupted - reduced - by a bad mixture), the AC heater might out perform the gas flame; which is normally not the case.
The "ON" time of the heat is dependent on the outside air temperature.
The hotter it is outside, the more often you will need to cycle the coolant.
The worse the efficiency of the heat source, the "warmer" the interior of the fridge will be for the same "fin" thermistor setting.
Obviously, if allowed to stabilize, the temperature inside will be identical. The wild card is the "weather" and the amount of cooling actually needed to maintain that temperature.
Hope that explains what I am trying to say, better.
