    Dryer Operation Overview Air enters the dryer cabinet, passing thru the heating elements (gas combustion chamber for gas models), and into the drum. The hot air heats the wet clothes and gradually removes their moisture in the form of water vapor. The moist air is vented through the dryer exhaust. Overall heating temperature is regulated by means of 2 temperature thermostats: an inlet control thermostat located near the heating elements and an outlet control thermostat located at the blower.
