Hello...I need help with my pellet stove. I have a whitfield profile 20 freestanding stove. The stove will turn on and feed the pellets and it starts up normally but after about 5mins or so the combustion fan turns off but the augur is still going and the stove fills up with smoke and it blows up. I have replaced the hig limit disc, cleaned out the photo eye and the whole stove. Any suggestions? Thank you!
