Section 2 Introduction

How Your Dryer Works

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.

The dryer has an automatic drying feature. At cycle start, when fabric is wet and the temperature inside dryer is

cool, the heat source (burner on gas models and heating element on electric models) is energized and heats the

cylinder until operating temperature (as set on Fabric Selector) is reached. Power is not supplied to timer motor

while heat source is energized during an automatic cycle. The heat source runs for longer periods of time in the

beginning of the cycle, when it is working to reach the operating temperature, resulting in very little timer

advancement. As the fabric dries and the cylinder heat is maintained, the heat source is powered less, allowing the

timer to advance to cycle end. If dryer heats but timer does not advance, refer to Paragraph 1.

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

• Disconnect electric power to the dryer(s) before servicing.

• Close gas shut-off valve to gas dryer(s) before servicing.

• Never start the dryer(s) with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the dryer is properly grounded.

WARNING

Section 3

Troubleshooting

IMPORTANT: Refer to wiring diagram for aid in

testing dryer components.

1. NO TIMER ADVANCE IN AUTOMATIC

CYCLES

For a description of Automatic drying feature, refer to

SECTION 2. If dryer heats but the timer does not

advance, perform the following service procedures:

Electric Dryers

1. Remove any damp clothing from the dryer.

2. Set the timer to an Automatic cycle. Set fabric

selector switch to Regular.

3. Remove the top 3 screws holding the control

hood to the rear panel.

4. Start dryer by pushing in timer knob.

5. Using a volt/ohm meter set to AC voltage,

measure the voltage across terminal “T” and

terminal “M” on timer. Refer to Figure 1.

6. Meter should read no voltage when the unit is

first started and the dryer is still heating.

Continue to monitor these points until the heating

element has shut off (this will take several

minutes even with an empty load). When the

heating element shuts off, meter should read 120

Volts and the timer motor should advance the

cycle.

7. If meter does not read 120 Volts after the unit has

reached proper operating temperature use meter

to check for 120 AC Voltage between terminal

“A” and terminal “N” (neutral) on the timer.

8. If voltage is present, recheck voltage between

“T” and “M”.

9. If voltage is present, but timer does not advance,

replace timer.

10. If meter does not read 120 Volts at “A” and “N”,

check the wire connections at the heating element

and timer (blue/black wire). If the connections

are good, UNPLUG dryer, remove wire at

terminal “A” on timer and perform an ohms

check on wire continuity between the heating

element and timer. If the wire shows continuity,

replace timer.
