furnace wont work
Hello fellow campers, right now as I type i'm camping.However, my furnace is not working!  . Here's what it is doing.....it cycles for 30 seconds and shuts off!....there is no "electronic ignition sound"... no smell of the burner lighting..(the gas is on ) it is a "Surburban" furnace hard to see the model the furnace is installed with no labels showing anyone had this issue? haow hard is it to replace an ignitor?

shut gas back off and wait for a second or two then turn gas valve back on very slowly.

Also if this is the first use of the season the air may need to be purged .
by lighting surface units on stove .

Turbo's advice for slowly opening the reg and bleeding is spot on. I have to bleed the lines after a few weeks of inactivity.
This manual might help you.
Edit: oops, wrong suburban manual let me see what I can find.

Can I get a clarification on "cycles"?
So when the unit calls for heat; the blower comes on and runs for 30 seconds; then shuts down?

Our old Mallard furnace used to do that if we didn't use it for a period of time.I had to do what Turbo said about lighting the stove to get the gas back to the furnace as they were very close to each other.Hope it works for you.

Thanks, but.... my stove is working beautifully so is my water heater. I wanna believe that there is an air pocket preventing gas recpetion.

Cthelite when the blower runs can you here the ignition clicking?On ours a few seconds after the blower would start you could here the clicking until the unit would shut down after failing to light.

I assume there is only one breaker or fuse for the furnace but did you check them all anyway?

I had one about a year ago..during that time i found that my battery was faulty (12v) the service tech told me that the funace depends on a the battery being in very good condition. HOWEVER! the ignitor was clicking then. it just would not light.

I had this same problem. Make sure the camper is drawing power from the campground and not the battery. Mine had a problem from switch to one or the other. And that solve the problem. Maybe disconnect the battery.

I had the same issue, theirs a sale switch that detects air movement from the fan, if the switch is bad, it wont allow the burner to fire.

This can be caused by lack of propane, a failed sail switch; Low Battery, dirty or corroded squirrel cage fan; or a bad circuit board.
My money is on a dirty fan. Keep an eye out for wasps when you open that puppy up.
