Ok, we had our Insert installed in the summer of 2008, so this is our 5th heating season using the insert and blower. I normally take the fan unit off the stove every 2 months or so and perform a solid clean out with the vac, compressed air, etc. (Even wipe the little blades in the barrel fan with a Qtip) So, after performing the cleaning, the right side barrel wheel just doesn't want to turn too well.....basically, when I shut of the fan, the left side spins for a good long while and slowly comes to a stop, where the right side stops much more abruptly. I got it cleaned up, and spins a little better than before...so it looks like I'll be needing to get a new blower for next year. I really wish the Lopi mfg didn't use damn rivets, as I could probably take it apart and just replace what is needed...hate to fork out $300 for a blower when its only 5 years old. We burn a solid 5 days a week for 12-14 hours, so perhaps this is just normal wear and tear?
