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.
