I guess what I really mean to say is do they lose effectiveness over a period of time? Even though they may not fail completely maybe they start to reduce their CFM output?
Wood Heat Stoves said:they may slow down a bit, but usually if output has been reduced the fan is on its way out...
mp3550 uses a small fan (only 30cfm i believe...)
if it struggles, we have a 60cfm aftermarket fan that can work,
we also stock the factory original draft fan from lennox, and aftermarket fan
is the air flapper/ draft fan cover flap open all the way??

EarthStove said:Thanks everyone. Dave, I will be in touch for the fire pot. I gotta get one one way or another since it's cracking pretty bad. Can you tell me if that steel is standard mild steel or is it stainless?
As for the blower fan, I may also try a new one if I can find something off the shelf for cheaper. Ours has 13 seasons under it's belt so maybe it's starting to give it up a bit.
bocephus said:I have noticed that I have the same problem as you every once in awhile. I notice that pellets (mainly unburned or smoldering) pile up on the right side of the burn pot and I only have a flame on the left side. This is the first time this has ever happened to me (hope reading your post did jinx me....haha).
Just like you I burn Ligs, have my Feed rate on Med. and my Fan speed on High. When i noticed the pellets piling up, I just turned my Feed Rate to the Fan only and just let it run. After about 5-10 min, all the pellets were burnt up. So, Im in the same boat with you. I dont know what this is all about, but its mildly concerning. The only thing that you have done differenty then me is break the entire stove down for cleaning. So i dont think you put anything back wrong, seeing that I am encountering the same problem without a heavy-duty cleaning yet.
Im thinking it might be the fan. I dont know how old my model is (any way to find that out....anyone???) but my burn pot is in good shape. So Im not sure if thats the issue. But if I can upgrade to a more powerful motor then I think that might be a good option for next years burning.
One more thing......I bought a few bags of my lovely Hammer Hott Ones, to burn durning that awful snow storm. And thats the first time I noticed the pellets piling up on the right side. Those pellets are alot smaller then the Ligs, so I think that more pellets per aguer rotation were getting in the burn pot and not burning completly. Interesting. Never had that problem when burning the Hammers before. The more I think about it, the more and more this is sounding like a air movement issue.........Maybe our fans are just wearing out like you said. Maybe we can get a discount when ordering 2 fans...............
