The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls room
temperature air in through louvers at the rear of the dryer and over the heat source (burner flame for gas and
heating element for electric). The heated air moves through the heater duct and into the cylinder, where it
circulates through the wet load. The air then passes through the lint filter, air duct, and exhaust fan, where it is
vented to the outdoors.

Motor is dead, will not run. • Refer to Paragraph 55 to check start switch, start
windings, and main windings.
Motor overload protector has cycled. • Wait two or three minutes for overload protector to reset.
If protector cycles repeatedly, refer to Paragraph 2.
Motor centrifugal switch sticky or plugged with lint. • Remove dust or lint and spray with “SLYDE,” No. 131P4,
to clean and lubricate.
Bind in motor bearing. • Remove belt and determine if motor shaft will spin.
• Replace motor if shaft is locked up.
Loose motor wire harness connection block. • Firmly press connection block onto motor switch.
Broken, loose, or incorrect wiring. • Refer to appropriate wiring diagram in SECTION 9.
Power cord is miswired. • Refer to appropriate wiring diagram for the correct wiring.
Refer to SECTION 9.
