I had a similar experience a couple of weeks ago. Came home to a cold trailer. Blower would blow but burner wouldn't light.
Turns out that the fan blades on the blower had accumulated dirt and dust on them which reduced air volume through the furnace. This prevented the Flow Switch from making contact and allowing gas to flow.
You may just need to open up the furnace and clean out the blower blades. Fairly simple, if you can get to the furnace easily. I had to have a tech come out and pull out the furnace, take it to the shop and clean it out. Works great now.
I found that my little 25 ft TT does not have a furnace filter in the intake. So I bought some "Filtreet" filter material, cut to size and fitted it behind the intake louvers. Now I can just open up the louvers, pull the filter, wash and re-install to keep the blower blades clean. $5 and change compared to a $280 service call.
