Furnace Question

[timr21]

Not that it's going to be a problem through the summer, but….

We just got back from a weekend trip to Cincinnati in our 2007 SV-235RS, and it got pretty chilly at night. I turned on the furnace, and the fan cranked right up, but after about 2 minutes it turned off without delivering any warm air. I tried this several times, and no dice. The furnace was working perfectly 3 weeks ago on a trip to Raleigh.

My first thought was that I was running out of propane, but the rest of my appliances (water heater, stove, fridge, oven) were all working just fine for the whole trip.

I don't want to mess too much with it (I'm not into things blowing up on me!), but I wanted to see if there was anything obvious that y'all think I might be missing?

Thanks,

The furnace is the biggest user of propane bar none in the camper.
If you can get 3 strong burners on high then propane "supply" can be ruled out.

I have attached a troubleshooting guide for the Suburban furnace to help you. Pay particular attention to the reset instructions and the "sail" switch" portions.

If the furnace fails to light 3 times it will go into "lockout" and will require complete removal of 12VDC to reset the control board.
