I'm a newbie to this site as well as popups. I've done a lot of searching on this site and others with no success. I recently purchased a 2001 Coleman Westlake that has the Atwood 7916-II furnance that I cannot get to light to save my life. I've tried and checked about everything I've read about here. The thermostat is on, and temp all the way up. I've bled the system and opened the valve slowly. My fridge and stove, both downstream work fine. I've checked fuses and breakers. The fan starts then 5-10 seconds later I can hear the valve open then a fast and strong spark for about 5 seconds before stopping. It goes through this cycle 3 times before the fan just runs blowing cold air. Where others have said their fan eventually stops and they get a blinking error message, mine just seems to keep running and I don't even see a light that would blink on mine. If I step outside I can smell propane from the exhaust port but only while the ignitor is sparking. Once it stops, so does the gas smell. The furnace was never used or attempted to be used by the PO if that is any help. I have gas and spark but no fire and running low on ideas. Any help or suggestions are greatly appreciated.
