Furnace won't ignite

[cdru]

The furnace on our travel trailer won' ignite. The fan comes on, but the furnace itself does not ignite. It is a forced air type with floor vents and a wall thermostat. I pulled the outside cover and noticed a little red light blinking. Any ideas??????? Thanks

Not to insult your intelligence, but are you sure you haven't run out of propane or the bottle is not turned on? The selector switch between your two bottles might also be in the wrong position. It's happened to me before...

Another possibility is that there is air in the gas lines. Try running the stove for a couple of minutes to make sure you have good flow.
