IMHO, consequence. On AC power, the fridge uses a resistance heater powered by line voltage to boil the coolant that makes the fridge work.
Low line voltage implies low heat output for the heater coil. Switch to propane if you have that option...
Some Dometics automagically switch to AC line voltage in an attempt to save propane. They don't seem to cool that well when they do that. On mine, you can force it to stay on propane by switching out of "Auto" to "Gas", IIRC.
