Duo-Therm Furnace


New Member
I'm new to RV's. Just bought a 24ft Nomad travel trailer 1977.
Ive been testing everything to make sure it all works. I'm having
problems with the furnace. It is a Duo-Therm 65900 series (model: 65925-023).
I am able to light the pilot fine, the vents are blowing out air, but it is cold.
It doesn't appear that the burner is lighting. The pilot will stay lit indefinitely,
but the whole furnace remains cold. I have checked the fuses, and all are good.
Please help!!

Re: Duo-Therm Furnace

I would take it that you have one of the ones with a gas valve that has positions of "off," "pilot" and "on." Is it fair to assume that once the pilot was burning you did move the valve to the "on" position?
