I have noticed that my blower doesn't seem to be putting out the CFM like it did when it was new, it's 2.5 years old and has been oiled every so often. I looked at it and the blower blades are covered in creosote. How can I tell if it needs changed? I cleaned the whole boiler out this summer really well so ash build up isn't an issue.

Sounds like you need to clean the creosote off the fan blades

[walkerdogman85]

Thanks I'll try and do that tomorrow

Keep a backup just incase! Dont learn the hard way like I had to last winter. My fan starting rattling and carrying on day to day. Mine to was also covered in creasote. Well during the coldest time of the winter my blower decided to take a dump. I could smack it with a hammer to get it to work but that only lasted for a few days. It kept binding up. Well long story short I had to take of work and go out every so ofter to open the dampner door so the fire would stay lite and the water temp to stay up. I had to drive 1 1/2hrs to my dealers house to get a blower. It was for a H2 model but it worked perfect until I got a new one. I now keep the one for the H2 as a backup..

Man that would suck! Ill get on it as long as its not raining. I should go buy a new one and keep this for a spare. Did you clean off all the creosote?

[DaveWertz]

Yeah I cleaned it but when they start to go theres nothin you can do about it. It may or may not help its def worth a shot. But mine did the same thing yours is doing now. It started chugging then slowly crapped out.

I've dealt with the same blower issue for my H5.  Pooped out last year when it was -20 and I got it going again after banging on it.  That afternoon I drove any hour to my dealer to pick up a new one and a spare cartridge for the pump.  I left the old blower on because it kept working with the intent of changing it out when things warmed up.  Well, this year when I fired it up the old blower has worked fine.  I say old (2.5 years)..  In my book that's not old and If I have to replace one every 2 years I ain 't gonna be happy...  So, I think before we get into the really cold air I will put the new one on just to be safe...  I realize things dirty and do have a life span but they are not cheap....

To all,

How is creosote building up on the fan blades. Are the furnaces back drafting?

My guess is that they are back drafting a bit..  Not sure if there is anyway to prevent this...  The fan blows air thru a short tube thingy and that tube thingy is covered in creosote...  The grate over the opening from the blower also has build up on it. 

[Steinacher Sales]

I am sure they are not supposed to backdraft out the air supply. The way it looks there are several of them doing just that.

Im going to say back draft as well. You figure when sitting there idling smoke will go where ever it can to escape. I have creasote build up on the flap and in the blower channel. I sometimes have to take a screw driver to knock some away..
