I know this is not bike related BUT.... I am wondering if there are any RV techs out there. I have a Suburban NT-30sp furnace in my RV and am having troubles with it. I have ruled out propane supply as I can run my water heater, 3 burner stove and oven at the same time. When i request heat the blower motor will start running, (sounds and feels quite strong), I can hear the ignitor click than a thud from the solenoid, than the burner lights and will burn for maybe about 5 seconds and than the burner will go out. It will repeat this 2 more times than the furnace fan will shut off after a couple minutes. Can anyone help me out on this one? Rob
