Will An Rv Fridge Run On Propane Without A Battery. This makes camping off-grid simple and relatively carefree. Propane refrigerators usually need a small amount of DC power to get started so you also want to ensure your RVs battery is on.
To run on propane LP an RV fridge does not require battery power but it does require battery power to open the gas valve and fire the igniter. When your RV is running on shore power the converter is supplying 12vdc to the fridge. Propane provides heat to run a cold body.
Because the converter is supplying 12vdc to the fridge it is drawing a little from the battery.
A 3-way fridge usually refers to an absorption RV refrigerator that can run off of AC Power LP gas and DC Power. A residential RV fridge will last for about 12 hours on batteries. An absorption fridge will run on batteries only for about 3 hours but if using propane too it will last for weeks. During this month it will be powering simple things like your water heater cooking tools and refrigerator.
