    I don't understand what you mean by two roasts. You can't start a second roast until the first is done cooling because when the cooling damper is open air is diverted away from the drum. But you said the cooling damper is closed. The only one other idea is that the chaff collector is full but again you said you cleaned the roaster. I am out of ideas. You will need to connect with the folks at the San Franciscan Roaster Company.

Did try to roast 400 grams last night same thing..
    If you don't adjust your damper - do you still lose air flow (past yellow)?

    I would suggest lowering the charge weight... down to say 400 and see if you have issues. It's rated at a pound which is 454 grams. Most people suggest roasting at 80% capacity... = 400 grams.
