Keystone Springdale furnace

[Duane4238]

My 2011 Springdale's furnace won't light. It's a Suburban SF-30F. When I turn the thermostat to ON, the furnace blower runs and I can here the clicking as it tries to light but after a few tries the whole furnace shuts off. Where do I start to troubleshoot? Thanks.

P.S. The propane tanks are full and the valves are open.

Told ya furnace was 'starving' for fuel

:B

Empty propane is easier to remedy then tearing into a RV Furnace

THANKS fo posting update!!

Well, I'm sure I'm not the first one! Went back to camp to bleed LP lines and check the sail switch. I fired up the stove burners and they lit for about 15 seconds, then went out. Went out to check the tank valves and both tanks are empty. I guess that's what I get when I let somebody use the trailer in November during deer season. Thanks to everyone for all the suggestions.

That switch is a Circuit Breaker/On-Off combo switch
When Off/Tripped-----NO DC to furnace for ANY functions

OP has DC otherwise fan and igniter wouldn't be working

Does the stove have a normal flame?

If not, or questionable, turn off the gas bottle. Turn on the stove to release gas pressure and turn off. Now very slooolllyyy open the gas bottle valve. Get the stove to light. Now try the furnace again.

If it does not fire after several times of turning the furnace off then back on there are two likely problems. Since you are hearing spark I don't think it is the sail switch. Smell the furnace exhaust as it tries to light - strong gas smell would indicate the spark electrode is worn or out of position. Weak or no odor would indicate a plugged burner orifice.

I agree sounds like the propane has not reached the furnace yet.My refrigerator does the same thing after the camper has sat awhile (I keep the propane off until we are getting ready to go on a trip)

I just light a stove burner for about a minute to solve the problem.

Sounds like the gas has not reached the furnace yet.

This would happen in my truck camper from time to time. I would leave the thermostat on and take a ride to fuel up the truck, by the time I got to the gas station, the furnace would be running. I think when the truck went bump-b-bump down the road it help move the gas along. Kinda like the human body .

Stuck sail switch furnace would NOT fire (click), try several attempts and then shut down

Furnace is 'starving' for fuel........IE: Propane just hasn't flowed to furnace YET

LP System needs a demand placed on it so regulator can be placed into service and establish flow

Try furnace thru several lighting cycles. Light off stove top burners to establish demand/flow

Thanks for the reply. That definitely looks and sounds like that could be the problem. My furnace doesn't have a door on the outside so I will have to disconnect everything and take it out from the inside. Outside door would have made it a lot easier. Happy Easter.

Sounds like a stuck "sail switch."
