Introduction

Fresh Air Combustion Air Mixed Air Exhaust Air

T008CE1A

Standard Models

How A Tumble Dryer Works

The tumble dryer 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.

10

NOTE: In Energy Saver Models, some of the exhaust air is recirculated. Refer to illustration on next page.

Section 3

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the tumbler before servicing.

• Close gas shut-off valve to gas tumbler before servicing.

• Close steam valve to steam tumbler before servicing.

• Never start the tumbler with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumbler is properly grounded.
