Thank you guys so much!!!
Getting ready to do some dry camping with our 2604WS and ran across this thread
There *IS* a better way to accomplish this than pulling the fuse. My Dometic has a light control switch right in the middle. It is contained in a plastic housing that is held in on the top of the fridge compartment by 2 screws. Remove those screws and drop the housing down.
You will find there are two connectors for wires into a circuit board. One connector has 4 wires and provides 12v, Ground, LAC control, and door light switch.
The other connector has two wires going into it of the same color. That is the offensive "heating cable". Examination of the circuit board shows connections from those two pins over to the 12v and ground pins of the 4 prong connector (this is a trick sometimes used to make wire connections). Just unplug that 2 wire cable to disable the heating cable and remount the switch housing.
I will do some meter measurements later and calculate what the electrical load is for this heating cable. And take some pictures and maybe add a switch to be elegant about this.
Note also the LAC is fundamentally a heating element too. In this case it is a 18 ohm 10 watt resistor on the circuit board in the light switch housing. This should only be an issue in colder outside temperatures where I believe they are preventing the fridge section from freezing. I would not remove that as it is not always on like the heating strip.
