Hi! My 1st post
What a great forum this is! And I only discovered it because of my furnace problem. Like so many, mine too started cutting out. I think we've only used it a half dozen times in 3 years on a chilly morning here in the Southwest.
How can you troubleshoot the dang thing when you can't see the error code the LED is showing!?
Simple. I put both the reset sw. and the LED on long wire extensions and remounted them where I could see the LED and if necessary do a hard reset.
Back in, mine showed 1 flash every 3 seconds = limit switch/airflow problem, a "Soft Lockout". (one of the 4 faults displayed by the LED per the manual)
I pulled it back out a removed the sail switch. Now unlike the pictures which show a bend in the sail, to capture more air, mine was a straight blade. So, I put a slight bend in the blade to get more air resistance. Voila! Problem solved
Hope this helps others.
