I have a Duo Therm 40,000 BTU gas furnace, I live in a fifth wheel RV. My furnace will turn on and heat for acout 12 minutes and then I hear a loud popping sound and the flame stops. So, I shut it off and back on and it will heat again for just a few minutes until the gas stops getting to it. Is it possible that I do not have enough amps coming from my converter to keep the gas flowing to my furnace? What would make it stop receiving gas to it. My gas water heater is doing the same thing. Someone told me that I might have bad propane or dirty lines, will this make the flame go out? I would really appreciate your opinion.
Thank You,
