Introduction
How a Tumbler Works A tumbler uses heated air to dry loads of laundry.
①When the motor is started, the exhaust fan pulls
room temperature air in through the air intake at
the rear of the tumbler and over the heat source
(burner flame for gas, heating element for
electric, and coil for steam).
②The heated air moves into the cylinder, where it is
circulated through the wet load by the tumbling
action of the cylinder.
③The air then passes through the lint filter, exhaust
fan, and is vented to the outdoors.
