My pellet stove got stuck and  has an error massage showing Comb Blower. 
I opened the blower and it’s plenty of chunks of soot accompanied by gunky sticky soot. I cleaned everything and it’s working now but I can’t figure out why this happened.
The glass is also covered with soot so obviously there’s a problem. I read some comments about air intake but I don’t know where to look. Any ideas?
