    Help Please: San Franciscan-1 pounder and Air Loss

    Hi I am new to the forum. I have a little experience roasting on a Kaldi wide, and came across a San Franciscan 1 pounder. My question is, I seem to be losing my air flow when I do the lighter trick. By the time the beans are turning yellow it won't pull the flame on my lighter, like I've lost air flow. I've cleaned it, taken the crossover pipe off and cleaned that, taken fan off and cleaned that, still not solving the problem. Any suggestions? Thanks.

    Parker - can you clarify your process. In your OP you state you lose your airflow during the roast - is this after you have changed your damper. Please provide your process and load size.

    No other ideas except to contact San Franciscan. Their support is excellent. The fan is quite powerful so you should have plenty of airflow when the cooling damper is closed. On mine a 50% exhaust damper setting will pass the lighter test all through a roast. There are safety devices on the roaster that are there to shut it down if there is insufficient airflow and those seem to be happy with the airflow you are getting. Since it sounds like you bought it used, taking a walk though with the folks at San Franciscan is the best advice I can give you.

    Sounds like that was from over heating. There is a safety check for that too.

    Are you sure you are opening and not closing the damper when you go to "3/4"? When the pointer is at 9 o'clock the damper is full open. When it is at 12 o'clock it is closed.
