As I mentioned in the pm to you, you can't shut it all the way off. The buttons will still glow blue. If you are worried about the fridge I suspect you are running it strictly on propane and not plugged in. If you are plugged in, then you don't need to worry about the draw off the battery. So yes, if you are dry camping and are using the fridge under propane power, then yes, it will still draw some off your battery. You just need to keep an eye on the level of your battery and recharge it as appropriate.
