Got down to 25 degrees here in central Colorado, so I turned on my furnace to keep the pipes from freezing. No heat
Fan ran and electronic ignition sparked through three cycles, but no ignition. Stove, hot water heater, and refrigerator worked, but not furnace. Not good. Cycled the thermostat and DC power, still no ignition. Drained lines and turned on a small heater. Hope the pipes are still good.
Next day late in the afternoon after it had warmed up in the upper 40s, tried again and furnace ignited!!! Guess propane had moisture in it and iced up in the furnace gas valve.
