Furnace fan blows but no hot air- a fix!

[Aiden’s dad]

My furnace Fan blows, but igniter won’t fire and getting no hot air. Not out of propane, and no tripped circuits.

I just watched a YouTube video from “our road to Camelot” the video: “Air blows cold but RV furnace doesn’t light”

I followed his great advice and it was the sail switch! He shows exactly how to locate, diagnose, and fix the switch. Took me and my son about 20 minutes- I’m so happy!

Btw, I spoke to a keystone authorized service center, and the rep told me almost every time you have a working fan, but no ignition—-> it’s the sail switch, a roughly $20 part (but in our neck of the woods takes 2-3 weeeks to deliver.)
