Frustrated... I have a pro series for a few months now and now its just wont smoke like it supposed to. Zero smoke ring. Its basically an oven. I am using Pit Boss pellets and when it first heats up it will smoke, but after 5 minutes it stops smoking. If I shut it down it will smoke while it cools down and when I start it back up it will smoke for about 5 minutes. I vacuum out the pot before hand as well and keep full water. This is all at the smoke setting - 200. I never go over 225 setting. I can have this thing running right outside an open window and I dont even smell the smoke whereas a month ago I couldnt keep the window open because the whole house would smell like smoke.
