I have had the same "clogged air pressure switch tube" multiple times now. I generally clean it out lightly with a toothpick and then blow thru it the best I can. It then seems to work for a while.
I have 2 questions. Do you think that just by replacing the switch it will work? And has anyone out there considered some form of filter on the intake tube to stop whatever from getting in there?
I'm not sure if the dirt buildup is from insects or dirt from driving, settling in the tube. As an experiment, after I cleaned it the last time, I took my handkerchief out, opened it to just one layer than placed it over the tube as a filter and the unit still fired up. Unfortunately I think that a filter could get clogged also if the dirt buildup was from simple driving down the highway.
Furthermore, at our last trip when I had discovered that the filter idea could work at least temporarily, while we were parked at the campground on a beautiful day, we were able to get it working in the morning (before we had the tube cleaned out) and by afternoon, it was clogged to the point of not firing up, no driving involved. So that may nix the getting clogged from dirt while driving.
Anybody else have any ideas?
One last comment, the temperature swing hot to just right to hot to cold, etc is driving me crazy.
