FOR SERVICE TECHNICIAN’S USE ONLY PART NO. W10042930

WARNING

Electrical Shock Hazard

Disconnect power before

servicing.

Replace all parts and panels

before operating.

Failure to do so can result in

death or electrical shock.

IMPORTANT

Electrostatic Discharge (ESD)

Sensitive Electronics

Do not open package until it is time to

install the electronic board.

ESD problems are present everywhere.

ESD may damage or weaken the

electronic board. The new board may

appear to work well after repair is

finished, but failure may occur at a later

date due to ESD stress.

■

Use an anti-static wrist strap. Connect

wrist strap to green ground connection

point or unpainted metal in the

appliance

-OR-

Touch your finger repeatedly to a green

ground connection point or unpainted

metal in the appliance.

■

Before removing the part from its

package, touch the anti-static bag to a

green ground connection point or

unpainted metal in the appliance.

■

Avoid touching electronic parts or

terminal contacts; handle electronic

board by edges only.

■

When repackaging failed electronic

board in anti-static bag, observe above

instructions.

DIAGNOSTIC GUIDE

Before servicing, check the following:

■

Make sure there is power at the wall

outlet.

■

Has a household fuse blown or circuit

breaker tripped? Time delay fuse?

■

Is dryer vent properly installed and

clear of lint or obstructions?

■

All tests/checks should be made with

a VOM (volt-ohm-milliammeter) or

DVM (digital-voltmeter) having a

sensitivity of 20,000 ohms per volt DC

or greater.

■

Check all connections before

replacing components. Look for

broken or loose wires, failed terminals,

or wires not pressed into connectors

far enough.

■

A potential cause of a control not

functioning is corrosion on

connections. Observe connections

and check for continuity with an

ohmmeter.

■

Connectors: Look at top of connector.

Check for broken or loose wires.

Check for wires not pressed into

connector far enough to engage metal

barbs.

■

Resistance checks must be made with

dryer unplugged or power

disconnected.

LESS DRY TEST

Begin with a fully assembled, empty dryer

with clean lint screen. Be sure dryer is

connected to a known good power source.

1. Set the following configuration:

■

Door - must be closed

■

Timer - Less Dry

■

Temperature switch - High

■

End of Cycle Signal switch - Louder

2. Press the Push to Start (PTS) switch.

After approximately 16 seconds, the

Timer will start to advance to the Off

position. If this function does not occur,

proceed to the Diagnostic Test.

DIAGNOSTIC TEST

This diagnostic test allows factory/service

personnel to test and verify all inputs to the

electronic control. The basic operation of this

test is to notify the operator with an audible

beep every time the status of an input to the

control changes state.

This test is performed with a fully assembled

dryer, connected to a known good power

source.

Activating the Test Mode

1. Set the following configuration:

■

Door - must be open

■

Temperature switch - Air Only

■

End of Cycle Signal switch - Louder

■

Timer - Timed Drying or AccuDry

Sensor Drying selection

2. Turn the Wrinkle Shield switch from Off to

120 Minute three times within a five

second period. A single beep, a pause,

then a single beep will sound to indicate

that the test mode is activated.

NOTE: If any of these initial conditions are

not satisfied, the control will not enter the

test mode.

Test Mode Functionality

When the control is in test mode, every input

change of state will result in an audible beep

(with the exception of the End of Cycle Signal

switch). This includes:

■

Door switch

■

Moisture Sensor (short/open Sensor

will result in a beep)

NOTE: A moistened finger or damp

cloth may also be used.

■

Temperature switch

■

Wrinkle Shield switch

■

Push to Start (PTS) switch (with the

door switch closed)

■

Timer (any cam input change will result

in a beep)

NOTE: Timer will advance during test.

If any of the inputs do not result in a beep,

proceed to the corresponding component

tests, beginning on page 4.
