Introduction
How A Tumble Dryer Works
A tumble dryer uses heated air to dry loads of laundry.
When the motor is started, the exhaust fan pulls
room temperature air in through the air intake at
the rear of the tumble dryer 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 wet load by the tumbling
action of the cylinder.
The air then passes through the lint filter, exhaust
fan, and is vented to the outdoors.

• Disconnect electric power to the tumble dryer before servicing.
• Close gas shut-off valve to gas tumble dryer before servicing.
• Close steam valve to steam tumble dryer before servicing.
• Never start the tumble dryer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumble dryer is properly grounded.
