RV Mechanic: Randall, RVIA Certification replied 2 years ago

Good morning! I am sorry to hear that you are having an issue with your furnace. I have an RV repair facility and work on these for a living.

I can tell you that the two most common causes of this are the control board is bad or the LP working pressure is too low and needs to be adjusted at the tank regulator. Most shops have a manometer and can do this for you if you remove it and take it into them. The control boards are made in China and poor quality and so I never sell them. I only install a good after market board made in Oregon by Dinosaur Electronics. Yours is a "Fan 50 Plus" model and sells for about $100 or so on Amazon. If you have an outside inspection panel over the furnace this is easy to get to. If not, the furace has to be pulled out from the inside.

I hope that points you in the right direction here. Please get back to me again if you need additional assistance with this. Thanks! Randall
