Section 2 Introduction How Your Drying Tumbler Works Fresh Air Combustion Air Mixed Air Recirculating Air Exhaust Air T007CE1A The drying tumbler uses heat, air and movement to dry loads of laundry. When the motor is started, the exhaust fan pulls fresh air in through the air intake and over the heat source (burner flame for gas and heating element for electric). The heated air moves into the cylinder, where it is circulated through the laundry by the tumbling action of the cylinder.
