How a Tumbler Works
A tumbler 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 tumbler 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.

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.
