There is a control board in both the refridgerator and furnace. These boards draw some power even when the unit is turned off.
:h That would be news to me ... can you substantiate that with a link to documentation indicating this is so? Not challenging you, just interested, as I'm quite careful about controlling parasitic draw in our trailer, even added kill switches to the radio and TV antenna system, also the climate control heater in the fridge.
Nothing runs in our trailer unless I know about it, including the fridge and furnace, so if I'm mistaken I'd like to know about it. :?
