GAS

VALVE

AIR DUCT

D282SE3A

The dryer uses heated air to dry loads of laundry . When the motor is started, the exhaust fan pulls room temperature
air in through louvers at the rear of the dryer and over the heat source (b urner flame for gas and heating element for
electric). The heated air moves through the heater duct and into the cylinder , where it circulates through the wet load.
The air then passes through the lint filter, air duct, and exhaust fan, where it is vented to the outdoors.
