Furnace help 
I have a question. I have a 1998 Fleetwood Bounder with a Suburban furnace SF model. I have fixed the grounding block, taped up the spark unit that's on the circuit board, and cleaned up all of the connections. The thing works great during the day, unless it's cold out, and then I have the same problem, but at night, like every other time it kicks on, it will not light and blow cold. I turn it off and back on and it lights and blows warm. I can't understand why it doesn't work and then works again 2 minutes later. Any ideas? Thanks in advance for your help.

Re: Furnace help 
You should watch this video for basic electrical troubleshooting on an RV furnace. My burner was coming on for approx 3 seconds and shutting off. I watched the video and saw they take out the ignitor/flame sensor and so I pulled mine and cleaned the flame sensor and now it works perfectly.
