I have a Breckwell Big E pellet stove that is just about 3 years old. I have had no problems to date and have always done the required maintenance. I realized today that it was cold in the house and when I went to check the stove the #2 light was blinking on the control board. When I press the power button to turn the stove back on it runs for approximately 15 seconds and then shuts back off. It makes two turns of the auger and then on the third turn of the auger it shuts off and the number 2 light blinks. I took the stove apart and cleaned it, including the vent. Put back together and still shuts off after the same amount of time each time. I emptied the pellets from the hopper and took the shield off that blocks the auger to make sure it was not blocked and its not. I am at a loss and dont want to start ordering parts if I dont need too. I have read some posts and read information on Breckwell's site. They state that when the number 2 light flashes it is always related to your airflow, or a loss of negative pressure. Any help would be greatly appreciated. Thank you in advance
