RV furnace problems
The airflow proof stands between a propane burner and your coach. Most no-heat faults stop there.
- RV furnace blowing cold air
An RV furnace proves airflow before it will admit any gas. The blower must reach a set speed to close a safety switch, and only then does the gas valve open. Blower running with no heat means the sequence started and stopped before ignition — most often because the blower never reached that speed, which on a weak battery has nothing to do with gas at all.
Drivable, with precautions - RV furnace clicks but will not ignite
Clicking or sparking is useful news: the sequence got as far as ignition, which means the blower reached speed and the airflow proof closed. The remaining candidates are all on the gas side — supply, pressure, the valve, or flame sensing — and all of them are technician territory because this is a propane burner inside your living space.

Not sure which of these you have? Structured triage starts from what you observed instead.
Next step
Work through structured triage for this system and you will end up with a written service brief: what you observed, in what order, and what has not been established yet. It is the document that lets a technician quote properly instead of guessing on arrival.
Being straight about what this is. No technician is signed to any territory yet — not one. We do not match you, dispatch anyone, or promise a call. What you get is the brief, and a request form that copies it to us so we know the demand is real. If you need someone today, take the brief and send it to a local technician directly; it works just as well that way.
