Hello everyone , i have an austin xl and this problem has happened to me twice already. When I want to smoke ribs, after the 4 or 5 hour mark, my pitboss stops producing heat but the pellets keep going. When I checked it in the morning the pellets overflowed inside but it was not burning. I restarted it and it was working fine. does anyone else have this problem and know how to fix it? Appeciate any help.
