Suburban Heater wont stay lit????

[kirk37r]

Went out today to start getting the Camper ready for the season.
When I turned on the heater it wont light.
The blower motor runs fine, when it goes to ignite there is just A short burst of ignition then it goes out (Maybe burns for 2 seconds) It will do this 3 times then it times out.
Stove and hot water heater work fine.

Turned the tanks off then back on. They are bothe full

Lossened the propane supply line at the heater and there is flow there. Don't have A meter to check flow.

When it does try to ignite there is the smell of propane but it wont stay lit.

Any suggestions appreciated

We hate to have to tow it back to the dealer if its A quick fix. It is still under warranty though

first thing I usually try
is blowing out the unit with some compressed air

for me and a few other's
this has worked the trick at times

of all
probably the easiest thing to do first

must also be venting properly

There is a post under Propane that has some more tips.
I had simmilar situation that ended up being an umbrella leaning over out side exhaust vent. Heater worked fine and then it didn't, it would start and then go out. Moved the ruined umbrella and all was fine. I have heard of mud dobler yasps blocking those vents too. I now keep those vent covers on.
Check out that other thread under Propane, I think it was from last week
