How Your Dryer Works
Lint
Filter
Section 2 Introduction
Cylinder
Heater
Duct
Blower
Fan
DRY1819S
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 (burner 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.
