i have norcold gas/elec fridge, it takes a awhile for the fridge to get the initial cold, but once it is cold i have to turn the temp down to 3 to keep it from freezing stuff in the fridge.
the transition from electric to gas and back is auto, but it does take a while to get up to speed so don't switch to often
and you need stuff in there to get cold, it does not like to chill a empty box of air
