A veritable encyclopedia of bad information has been published online about the humble RV furnace. If your RV furnace is not turning on, I highly advise you to take the Top 10 pages on Google and stuff ‘em in the digital trash can. For instance, I saw several articles that suggested “poor gas flow” could prevent an RV furnace from turning on, which is absolute hogwash.

I will share with you 7 things you can check if your furnace is not working – and by “not working,” I mean zero response. No blower fan, no ignition, nothing. Dead in the water.

This article is NOT comprehensive. Unless you know how to use a multimeter, there are some things you just can’t check. But before you call an RV repair technician (like me), cross these troubleshooting items off your list first.
