I have been scratching my head, and posed this question last year at a rally. My Dometic RM3600 3-way fridge runs great on LP & 120V but nothing on 12V.
Have finally gotten around to learning more about this specific fridge. It was lower on the priority list than a few other things. And managed to track down a pdf of the diagnostic manual for these units. Seems there are 3 connections in the harness at the back. 2 are for the actual wiring to & from the battery. The 3rd is an ignition interlock. This is designed to keep the fridge from running on your battery unless the ignition is on and running. Keeps the fridge from draining your battery. The unit will not run on 12V without this circuit.
My interlock is an empty socket. So it appears I will have to run something to the ignition (I, meaning someone that knows what they're doing!) in order to use the fridge while driving without resorting to LP.
I'll post a picture when I am back on the computer. Just FYI for anyone else with a similar issue.
