OK guys, been listening to this blower making a weird noise on High for 2 months now.Did a good cleanout this Fall with compressed air, but never too the Blower motors off this year.What can i say, took it off today, expected maybe bearing gone in the shaft,sounded like the drum was loose and Hitting side.PETS + Pellet Stove= YIKES. 1 Dog, 2 Cats, guess i'll know to pull them off next year before firing it up.
