Dometic Fridge?

Hi there,



Can anyone tell me about how a Dometic fridge works?



I have one out of my rig and want to see it is working. I plugged in the AC cord and nothing happens on the control panel. Does it require 12VDC for the AC side to work?



I'm guessing all the AC does is replace what the propane does when running on gas and that the fridge must have 12VDC at all times.



Thanks,

Pete
