How Your Dryer Works

LINT

FILTER

Section 2 Introduction

CYLINDER

HEATER

DUCT

EXHAUST

FAN

DRY14S

The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls 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.
