Furnace fan works for 30 secs with No heat

[Jorgensons]

Previously all functioned fine. We recently had our first freeze. Turned the furnace over to heat. The fan kicks on for 30seconds before kicking off. Never hear propane kick on. Is this just a pilot. Worked previously with No problem, no changes?

Sounds like no flame maybe. Can you hear If it fires? Got gas?

Most, if not all Heartland trailers use a direct spark ignition furnace - there's no pilot light. Make sure the air is purged out of your propane lines by lighting a range burner and running for a minute or two. If the furnace still doesn't light, close the valves on the propane tanks, wait 10 seconds, and re-open verrrry slowly. If opened too fast, the overflow protection device is activated, reducing or shutting off flow of propane.
