I recently replaced the exhaust blower, after the original died. I have cleaned the stove, from stem to stern. The stove will just not stay lit after the first five minutes I have added pellets to the pot before turning it on. The ignitor comes on, because a fire starts. The auger is dropping pellets into the pot, I can see them. The flame gets big, and then just slowly peters out. The auger stops dropping pellets, and the stove shuts down. After trying this for five times, the stove will finally light for some reason. Is there some type of sensor that is not tripping? Is my new blower the cause? Any suggestions?
