LGM Furnace Not working

I wonder if anyone has had a problem with the furnace? I had the thermostat set for 45 degrees but I found this morning that it had not gone on during the night - the inside temp was down to 32 dg.

I tested the cook top - propane is (semi) full. Everything else is working fine (battery checks out good, etc.). Went back just a bit ago - sun is out, inside temp was up to 42 dg. Kicked up the thermostat to 55, furnace kicked on (blower) but then shut off.

Ideas? Thanks very much.

I don't know this model and haven't read the manual but many furnaces don't come on under 55 on the thermostat. B have you tried setting it to 65 or higher just to test it?

@dres Thanks! I didn't know that. I'll try it and post back here either way for others.

I tried it at 68+ degrees. Same result: blowers kick on, then after only seconds shuts off....

Having the same problem (2020 LGM)!  Called the dealer and was told the following: could be one of two issues.  Try to turn on the furnace and then run outside by the exhaust before the blower stops; if you smell propane there, the problem is likely a faulty igniter (which requires a dealer to repair).  If you do not smell propane, it is likely that part of the furnace's internal mechanism has stuck (due to pet hair coming into the air intake or other causes).  He said you can either lift out the mattress, unscrew the board covering the furnace, and then rap on the furnace casing a couple of times; or hitch up the trailer and drive it over a couple of good bumps.  He said the odds of either of these methods working is 50/50.  Of course, if it doesn't work, then it's time to take it to the dealer.

Of course, the problem could simply be air in the propane line.  I was told to always light the stove first (after turning on the propane bottle) and let it run a couple of minutes to bleed out any air in the line -- THEN try to light the furnace or refrigerator (if it's using propane).  Best of luck!  I'm interested in hearing how things work out for you!
