Since the rig was new, the furnace has been really noisy at start up, but figured it was just because it was much larger than my last unit.
Sometimes everything is normal, but more times than not, the blower starts, then the gas valve opens and will ignite. It then sounds like a jet powering up for takeoff and vibrates the floor and cabinets. Sometimes it take 2 or three tries for it to ignite, but this last trip it was in the low 20's at night and I would wake up cold and the furnace failed to light. I would then reset the thermostat and try again before going back to bed.
I have a screen over the inlet/outlets, but it had this problem before I installed it. I have tried a separate tank/regulator combo with the same results.
It really sounds like it is a lean fuel condition due to the violent nature of the hum followed by the flame going out, but I'm no appliance mechanic either....
