Well, today I figured out how to 'slide out' the entire "main" blower fan, motor, and control board. Had to unhook a bunch of wires of course, but I took pictures, and labled them. We spent 45 minutes just cleaning the 18 ? yrs of Gunk built up on the squirell (sp?) cage fan and housing.(it was gross, but we've only been here 8 yrs....) I cleaned the rubber tube going from the induction fan to the pressure switch, cleaned everything I could find. Put it back together, and I'm sure it's not right, "Because I had No Leftover Parts !!!" Anyway, it fired up and worked fine, but then again the glitch we had only acted up once in a while, so we'll see. I'm sure it's better than it was.
Once again I THANK YOU to everybody for your input ! I have learned a lot from the Great people here on this forum, on many things.
