Refrigerator Cooling, Propane vs. Electric
Question about refrigerator cooling during preparation for a trip. Does it cool faster when plugged into electric (in my driveway) or just leaving the propane on and cooling that way? Thanks for any ...

The BTU output of 120 and LP are almost identical. There are factors that affect how well and fast either source cools better. BUT, BOTH will be equal as long as all operational parameters are to spec.
1. 120 line voltage will affect 120 operation. Anything below 114 volts will not allow best 120 cooling.
2. LP gas pressure and the condition of the burner and burner Chimney will affect best LP cooling. Low(below 11 inches W/C) it will not cool as well. Dirty burner or Chimney will not allow the Heat BTU's to be efficient.
Last, for some reason some think because it is a HOT flame, it MUST cool better. NOT SO. The Flame itself cannot heat the boiler system to operational temps. So, ALL RV refers have a metal spiral baffle in the Chimney just above the flame. THAT spiral baffle causes the LP flame to disperse into a round heat source to heat the Boiler system efficiently. The 120 element is attached to that boiler system and is 6 to 8 inches long and transfers its heat directly to the boiler system. Remove that baffle and the LP would not cool at all. So, BOTH LP and 120 are even in cooling. A reason to run on LP would be if you have verified that the CG or source of 120 is below 114 volts. This may happen in areas where high RV usage and AC running has dropped the line voltage. Doug
