Low voltage in a cold campground. January 11, 2013, 12:47:49 pm Yahoo Message Number: 136153Hi Steve. I'm puzzled why you think that 100VAC would be dangerous to your refrigerator, especially in cold weather. The cooling unit run by the electric heating element should have plenty of reserve capacity, and 100 volts isn't much different than 115v. The 12 volt logic board should be unaffected. Maybe you are thinking of compressor style refrigerators where the start up motor may have to overcome freon pressure in the compressor 'cylinder' without benefit of inertia. Most newer refrigerators and air conditioners have scroll type compressors and not piston. Running a heat pump type heater is about the only thing that might be damaged by slightly low AC voltage.

The A/C is another reason should it be in use.Steve S. Lazy Bones & JiggsSteve S. Lazy Bones & Jiggs

It uses resistance heating which would simply draw slightly less power on low voltage. It is also my view it is unlikely to harm the power converter provided it was operating at less than 100 percent capacity. The air conditioner would be the primary issue with low voltage, and especially if it was very hot out compounding any thermal issues from excessive current draw. My Dometic is rated at 115, not 120 volt AC w/ plus minus 10 percent tolerance.

Reply #3 – January 11, 2013, 08:29:37 pm Yahoo Message Number: 136165To add: If it were mine, I'd operate without any guilt the refrigerator and power converter at 100 volts (with the caveat that the power converter was at moderate output or less in less than blazing hot weather). I would run the AC down to 103.5 volts in any weather because that is the spec for it.
