Our furnace is running/blowing- will blow hot air for a few minutes then turns to cold air.  Propane is working - can light stove burners no issue.  Bypassed sail switch and same issue.  Anyone experience this?  We are suppose to head down South tomorrow from Nova Scotia- but obviously will have to boondock at least one night on the Northeast Seaboard- we're running down the 95- and heat is imperative!  Any suggestions welcomed!

He's tearing it all apart this morning- fingers crossed we can get to the bottom of it- luckily we aren't on a schedule just anxious to get out of the cold!  He's been reading the posts - he's a diesel mechanic so propane furnaces are all new to him!

Yes- no obstructions in exhaust vent- plenty of batter power- shore power, and generator- all the same result.

You check for obstructions in the exhaust vent? Enough battery power?
