I own a quadrafire Castile pellet stove that has been working fine until all of a sudden I look and notice it's shutting off. I thought for a moment that it may have reached temp but it's still 5 degrees from its preset temp. So I hit the reset button to get it to feed pellets again and nothing. I continue to press the reset button and nothing happens no sound nothing. It's like the reset button. Why would my reset button not work? And how could I fix this? Any help would be greatly appreciated.
