Question: I just bought an RV. When I left the dealer the refrigerator was set to Gas. I thought it should be off so turned it off. But now I think I should have left it on. Can I just turn it back to gas, or what?
Answer: There is no technical reason why you cannot switch it back to propane. RV refrigerators are designed to switch between electric and gas. Some will switch automatically; some switch manually.
We keep our refrigerator on electric whenever a campground includes electricity in the site rental. We use propane when we boondock/dry camp or whenever we want to quickly cool down the refrigerator when it has been off over 10 hours.
Another instance when we might keep the refrigerator on propane is whenever we have limited electric power like while plugged into a 20 amp outlet at a friend’s driveway.
