I spent a lot of hours last year unjamming auger motors. With the price of gas and time on the road the average cost for unjamming an auger motor runs about $120. I would recommend getting one of theses Pellet Hoppers with a built in screen to screen the pellets before you put them in you stove. It will help prevent auger jams and extend the life of your auger motor. The problem is with broken pieces of pellets and saw dust that we call fines. Also that last couple of cups in the bottom of your bags of pellets, that is just sawdust, DON'T put that in your pellet stove. The Hopper runs $299. You can build your own screen but in the long run this is a whole lot easier. Call Robin @ 916*705*8609
