I finally figured out how to run the fridge off the battery while traveling . I’d turn the battery disconnect on and nothing to the fridge . Up in the cabinet to the left of the control panel is a switch that says remote on , I had assumed it was for a remote generator if equipped , but it turned out that turned in the inverter to run the fridge . I had looked a lot on YouTube and could find nothing had started to assume it was my inverter that was bad . There was nothing in my owners manual regarding it either .

I figured it out the hard way. Took the rig to a dealer for winterization, got it back with dead batteries (2 different dealers!). Why they decided to plug it back in to the inverter I'll never know.

Thanks for this. Any chance you can show me the switch on the control panel?

If possible, could you let us know the Fridge make and model, and also more about the switch location. Maybe a photo or two?
