We ran out of propane overnight and now I can’t get my furnace to ignite. The water heater and stove are both ok, but the furnace just blows cold air and shuts off. Thoughts?
Need to clear air from the lines, It could take numerous times depending how much pipe is involved. My guess would be 5-10. Next question, are you running off batteries? They culd be low not allowing the fan to come up to full speed which closes the sail switch.
