Kinda new to the pellet stove world and learning as I go. I have a 2006 mt vernon pellet stove. Last year I replaced the exhaust fan and everything had worked as it should until now. The last few days the fire every once in a while, seems to get bigger than normal, and it tripped the "resetable" snap disc on the auger. When it did it obviously shut down. The pelllets in the pot did not completely burn and it left black soot in the stove. Before I go too far and try to fire it back up and have even bigger problems, I was looking for some advice as to what would cause it. I regularly clean it as far as heat exchanger, ash pan and general vacuuming of all the ash out of the stove. Any help/advice appreciated.

I had some ash built up a little in my chimney corner, where the chimney turns upwards in the wall. Cleaned that out and it was working better for a littlw while, but then the flam started getting big and lazy again and my pot has been over flowing. The combustion blower was replaced anout 2.5 tons ago. I have a chimney that comes out of a hearth where a wood stove used to be. But yeah clean. Have had all the baffles out and have cleaned behind them. Cleaned the heat exchanger tubes. Neither had any build up to speak of.

ok only 4 things can cause a lazy flame,
1: exhaust is restricted from combustion blower to the rain cap
2: exhaust path through the stove is restricted
3: combustion blower isn't doing its job
4: house is very well sealed and it can.t draw enough air in through the intake to maintain a fire.
I would recommend pulling the combustion blower and give it a good cleaning and the chamber it mounts into. should be done every ton. lots of ash gets back there and packs up

I cleaned it all out, but haven't pulled the blower. I did it from the side plate access. Thw flame had been fine, but it keeps overfilling the pot. Feed rate rod is at it's lowest setting. Its like thepellets aren't burning completely, but it keeps dropping them and then it backs up into the feed chute.

Ok what about the chimney/liner when was it last cleaned and brushed? Have you checked the rain cap area for obstructions, birds nest?
