I have a Dometic model DM2652 refrigerator. It uses 1.3 amps continuously when hooked up to gas/battery. I checked the schematic in my instalation manual and discovered that there is a 12 volt heater cable that is ON all the time. I guess its function is the same as in a household refrigerator: prevent condensation around the door in humid weather. My household refrigerator has a switch for the heater; my Dometic does not. Has anyone installed a switch to control this heater, and if so did it work out well? If I could turn the heater off, my battery would last much longer when dry camping which would save me a great deal of grief.
There SHOULD be a switch to turn off the "climate control" and it is usually located above the freezer door inside of the door frame. It should ALWAYS be turned off when dry camping as it is a fairly serious draw on your batteries. Just open the freezer door and look along the inside top edge.

Out of curiosity, where in the 'Dacks are you? You'll find us canoeing anywhere from Cranberry Lake to Wilmington.
It appears that Dometic has made a change to this model (and not for the better) The owners manual that came with my fridge identifies only the NDM 1062 as having a climate control switch. The DM 2652 does not. My camper is a 2012 built June 2011 so I assume it is the current model. In any case it looks like I am out of luck unless I install my own switch.
