Exclamation Trailer Furnace Does Not Heat

I have a park model trailer in a trailer camp in Sussex, NJ that is opened from April through October. We have a Duo Therm Propane Furnace that we use on cold nights in spring and early fall. At the end of a spring weekend, we left the thermostat on and turned off the propane. The unit ran during the week (I suspect at night when it cooled off) but could not heat the trailer because the gas was turned off.

Now it blows cold air when I turn it on. I do hear a clicking but no heat!

I thought I might have to replace the electric pilot light which I hear clicking.

Any ideas?

Keep cycling it to see if it purges of air. Sounds like you let all the gas out of the line up to the valve you shut off. Do not know age of your unit, but if newer one, also shut off breaker to furnace to reset furnace control, as it could have gone into "lockout" due to it trying to fire 3 times with no success. Igniton modules are designed to do that.

I agree with ecman. You may have to cycle it several times before it will fire.

If this furnace lights a pilot via a spark, it is possible an insect may have gotten into the pilot assembly & built a nest thus blocking the flow of gas.
