The propane furnace/heater on our LQ trailer will not work properly and since my husband and his friends are pretty darn handy and since the nearest repair place is 2 hours away, I thought I'd write to y'all to get some suggestions on things he needs to check or try to repair it.

Jim says he has cleaned the thermocoupler and cleaned some other things (pardon me but I'm at home with the sinus crud and typing this is as ambitious as I have been or will be all day.)

Jim says the pilot light will light and the fan comes o but the furnace stays lit for only a few seconds. He's tried with the electric running and with the generator running.

Any ideas what is wrong and what he should try?

Thanks so much in advance for any wisdom you can impart.   

Didn't get a manual for it with all the other booklets and manuals that came with the trailer.  Didn't realize we didn't have the manual til we needed it.

Figures.

Try searching the internet.  First the manufacturer of the furnace, then just google the manufacturer and model number

Just searched and pasted 10 pages of info into a word document.

May be the sail switch?

Thanks,

KR
