One of the best parts about camping in an RV instead of a tent is that you can do it all year round. While in a tent you’re subject to the whims of Mother Nature, but your RV will always be cozy because of insulation and a working furnace. Much like a house furnace, an RV furnace has a central spot that creates the heat and a series of ducts or tubes that carry the warm air into the various parts of the interior. This basic design exists whether you’ve got a large motor home or a smaller trailer version.

Like any other system, your RV furnace needs occasional maintenance, but it’s a minimal contribution for this appliance. There’s not much that can go wrong on an RV furnace that’s actually fixable by the average owner, so checking for problems is going to be your biggest chore and contribution.

In this video, you’ll see how to access the furnace underneath your RV body. You’ll see visuals of how the different types of duct work transports the warm air to the colder parts of the interior. An RV furnace needs both battery power and a fuel, such as propane to function. We’ll also talk about the minimum amount of battery power needed to keep your RV furnace running. If your RV furnace isn’t working right, there are things to check, and you’ll learn about them here. Find out how to troubleshoot problems with the exhaust, and even how to take apart the thermostat and cross wires to double check the sparking mechanism that starts the furnace underneath.
