dougrainer, go to 55 seconds in this video: click here.
This is similar to what mine looked like last night when I pulled it. Although mine was not that dirty. There was just enough lint and cat hair caught right where the sail hinges to the switch itself, preventing the sail to push the tiny button behind it. I simply removed the "wad" and blew the remainder out. Furnace has cycled well ever since. We are in it now. It's getting cold outside! Yuck, rain and cold in Indiana today!
Did not state it does not happen, just I have never seen it bad enough to need a cleaning and then it worked. YOU are a prime example on these forums of finding a real problem, then assuming it is a common problem. Doug
