I have a Quadra Fire Mount Vernon OE stove which is about 5 years old. Today I returned home to find the fire box full of flames. Upon closer inspection I found that the auger motor was continually running and overflowing the pot, the pellets were backed up into the shoot. I didn't want to unplug the stove and stop the exhaust fan so I quickly removed the side panel and pulled the wire feeding the auger motor. After the pellets were burnt up and the stove cooled down I started to look into the problem. Basically there was a constant 120v being supplied to the auger motor. There was no call for heat the red light was off (the room was 10 degrees above the thermostat setting). I unplugged the stove for a minute and then started it back up to verify the problem but I couldn't reproduce it. I guess resetting the controller fixed it at least for now. But I'm afraid to run the stove unless I'm in the room with it. Talk about a bad failure mode. I'm just glad I came home when I did. Is this a common fail mode for the controller?
