I am not an expert on this either, but I believe 12V power is needed for the fridge control panel, the fridge interior light, and also for the fridge external cooling fan(s), which are there if you have a side venting refrigerator. Also, 12V would be necessary to power the temperature thermostat for turning the vent fans on and off, and also to power the "thermister" on the inside of the refrigerator, that is attached to the cooling fins. If you have an ice maker in the freezer, then you also would need 12v power for that, for dumping the ice, and for releasing more water into the "ice tray:. Plus, as you say, power for gas ignition.
