need help with my fathers stove its a 55-shpep. there was a lot of dust in the home so we did a dollar bill test, seems like many parts of the gasket was flat and not making a tight seal. he squeezed the rope gasket and pulled it out a liitle and it past the dollar test and the dust has reduced considerable, will change in summer.. NOW the issue as you see in photo, the burn pot is filling up with ash and its not blowing into the ash tray. i thought it could be mosture or blower issue. background.. the stove had a full cleaning in early january, using green team pellets stored in garage. its still cold in ny please help..
