Introduction
How A Tumbler Works
The tumbler uses heat, air and movement to dry
loads of laundry.
When the motor is started, the exhaust fan pulls
fresh air in through the air intake and over the heat
source (burner flame for gas, heating element for
electric, and coil for steam).
The heated air moves into the cylinder, where it is
circulated through the laundry by the tumbling
action of the cylinder.
The air then passes through the lint filter, exhaust
fan, and is vented to the outdoors.
NOTE: In Energy Saver Models, some of the
exhaust air is recirculated. Refer to illustration on
next page.
