I fired up my Quadrafire Castile pellet stove this Fall, and it is feeding too many pellets, causing a very high fire - even on the low setting. I closed the feed gate as far as it will go, but the problem remains. The stove sounds like it is running the pellet feed auger much longer than it used to on each feed cycle.

Is there a potentiometer in the control box that I can adjust for the feed rate?

Any other recommendations?

Thanks!!
