03PaceArrow Furnace Won't Work

[kgarvey]

Camping with a friend who just bought an 03 Pace Arrow 37A. His house furnace won't turn on. He set the Climate Control to 'Heat' and pushed the temp thermostat up to 80 degrees. Nothing. I'm wondering if there is another switch that controls the furnace from inside the RV. We pulled off the access panel and verified the power switch on the furnace was on. Did a voltage check on the leads coming to the furnace from the inside of the RV and no voltage. This may eliminate the pc control board as being an issue if there is no voltage coming from inside the RV. Also checked all DC fuses and they all appear to be in working order (though we don't have a legend telling us which DC circuit is which.) Pulled the Climate Control panel off the wall and verified that all wires were connected as expected.
Anyone have any ideas regarding what else we can check before we call in a service technician?

Thanks, everyone.

Its probably too warm out to come on?

This may be a stupid question......but.....is the propane turned on?

There are no stupid questions....appreciate your response and reminder about the propane. Checked that, and it's not the issue. But, here's a postscript...
We left the Climate Control set on 'Heat', and 20 minutes later the 30amp Main circuit breaker (which is ponied to the 20 amp breaker for the climate control) over heated. We just finished replacing this Main breaker and put in a separate 20 amp breaker for the climate control. Low and behold, behind the main electrical panel is the Climate Control Box screwed into the wall, no where near the Climate Control center. Clearly, there's an issue with the Climate Control Box that caused the 20 amp breaker to break only after it sucked to much current through the main. The climate control box is nearly inaccessible (thanks again, Fleetwood...ever heard of human engineering?) Anyway, it's now a job for a professional.

Thanks to you both for your quick replies. Always interested in other opinions, so please respond if you can add any light to this issue.

And thanks for moving this post to the proper forum. Still learning about that stuff.
