Alrighty, so it's that time of year again so we decided to drag the tent trailer to our local campground for the weekend. We were having issues last September that, according to the diagnostic LED, was a limit switch/air flow problem. Changed the switch, thoroughly cleaned out everything I could get to and still no heat. The blower comes on strong, I can hear and feel the gas valve kick on but can't hear the igniter at all. I'm leaning towards this as the problem, just wanted to get some opinions from people that have been doing this a bit longer than I have. Are these a known issue especially with such low "miles" on the trailer?
