HELP. On our first outing with brand new unit. Guess we should have tried things a bit more before leaving dealer. Read a lot of the comments on here and nothing works yet. Turn thermostat to furnace and setting on 80F. About 36F outside right now in New Orleans! Furnace comes on as the manual states and runs a few mintues. I can hear the ignitor trying to start the flame. I believe it does that a few times and then the motor eventually shuts off. No heat. I presume the burner is not starting. We have turned the burner on the stove to ensure gas flowing. Already tried turning the main propane on and slowly back on. Even tried disconnecting from main AC supply and ran generator. Still does the same thing. Am 600 miles from dealer so hope it is just something I'm doing wrong with this new unit. Need heat!! Too cold for heat pump to really work. Ideas?
