I have a Goodman GMH80 gas furnace and it quite at the end of last season, I found that the pressure switch was bad electrically and replaced it with a new one. (I actually took it the old one apart to see what happened to it, I cleaned and realigned contacts and switch now works). Today I hear the blower (for exhaust) starting for a couple of seconds then stopping, keeps repeating, same as last time. I put in a new pressure switch which I had in stock and furnace works OK now. The one I took out has the same problem, it's bad electrically.
Any comments, should I replace it with a different brand (universal one like... Cleveland Controls)?
Thanks... Charlie
