How Your Dryer Works
DRY1819S
Cylinder
Exhaust Fan
Gas Valve
Air Duct
Lint Filter
Heater Duct
Introduction
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.
