USSC (Wood/Coal) Furnace Distribution Blower. The distribution blower is responsible for circulating room air around the furnace and into your ductwork. If the blower is not working as it should, the amount of heat transferred from the furnace into your home may be reduced. If the fan has been cleaned thoroughly and is not moving the same volume of air as it once did it may need to be replaced.
