My stove stopped feeding pellets I called the store and they sent someone out. After they checked the stove they replaced my auger motor. The tech said because the stove augers pellets up any sawdust is left behind in the tube and mine was packed with the stuff. He said after each ton just let all the pellets burn thats in the stove and then stick a vacuum in the pellet bin and vacuum any dust in the bottom of the auger shoot. He said sometimes I might have to reach in a shake the auger a little to make the dust fall down. That's it
