I have a Quadrafire Mt Vernon which initial start up in the morning has ashes blocking the ignitor hole. The stove runs thru the cycles correctly. It is just when the stove starts up in the morning that the hole is blocked. It automatically turned down at night to 56 and back up in the morning but in the morning it will not restart because of ashes blocking the ignitor hole. If I come down in the middle of the night and clear the clump away it will start right up in the morning. I using Great American pellets stored on pallets in my basement. We had a very wet fall and I have a dehumidifier running. The problem didn't seem to start until I to the bottom of my first pallet. I just started at the top of my second ton so maybe it will stop. Are there any subjection I can try if it continues. I did replace the ignitor.
