furnace not working

We are out on our last camping trip of the year and our furnace has stopped working . I have checked all the obvious, plenty of propane, fuse in the converter, even tried bypassing the thermostat. It was working and cycling last evening, but nothing now. Any ideas for a quick fix.

thanks in advance

Mr. Heater is a good idea but my furnace quit a year or so ago.  It was a real trick tracking down the problem, which turned out to be a shorted wire between the furnace and the thermostat.  It was a chore replacing that wire.  There is a post about it on here somewhere.  I hope that's not your problem and it's really not very likely to be.  I could bypass the thermostat and get the furnace to work by jumping a couple of wires at the furnace.  If it doesn't work when bypassing the thermostat it seems safe to assume the thermostat isn't the problem, in which case it could be the control board on the furnace.  Just guessing at this point.

Good luck.

Update:  After we got home, the heater started working again although intermittently. Having read about the sail switch on this forum, I took a fan turned it on high and forced air through the front grill of the furnace. After I cycled it a few times, it now seems to work properly. I am guessing that perhaps the sail switch was sticking as we have not used the furnace much this year or any year.  So I think  that is good to turn your heater off and on a few times each trip to keep the sail switch working properly.
