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 Sensitive
Electronics (ESD)
ESD problems are present everywhere. ESD
may damage or weaken the machine control
electronics. The new control assembly 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 machine control
electronics by edges only.
When repackaging failed machine control
electronics 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? Was a regular fuse used? Use a
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
Ω
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.
DIAGNOSTIC TESTS
These tests allow service personnel to test and
verify all inputs to the machine control electronics.
You may want to do a quick and overall checkup
of the dryer with these tests before going to
specific troubleshooting tests.
ACTIVATING THE DIAGNOSTIC
TEST MODE
1.
Be sure the dryer is in standby mode (plugged
in with all indicators off, or with only the
Clothes Dry indicator on).
2.
Select any one button (except Stop and Cycle
Signal) and follow the steps below, using the
same button (remember the button):
Press/
hold 2
seconds
Release
for 2
seconds
Press/
hold 2
seconds
Release
for 2
seconds
Press/
hold 2
seconds
3.
If this test mode has been entered successfully,
all indicators on the console are illuminated for
5 seconds with
showing in the Estimated
Time Remaining three-digit display. If there are
no saved fault codes or active fault codes, all
indicators on the console will momentarily turn
off, then stay on with
displayed. Continue
with diagnostics.
4.
If entry into Diagnostic Test Mode is
unsuccessful, choose a different button (except
Stop and Cycle Signal) and repeat step 2.
If no indicators come on after repeating step
2 using a different button, go to TEST #1,
page 4.
DIAGNOSTIC: Active Fault Codes
If there is an active fault code, it will be flashing in
the display. Review the Display Fault/Error Codes
table, page 3, for the recommended procedure.
If there is no active fault code,
will be
displayed and all of the indicator lights will be
turned on.
DIAGNOSTIC: Saved Fault Codes
If there are saved fault codes, the most recent
fault code will show “F:” and flash “XX” where XX
is the fault code.
Press and release
the same button
used to activate
diagnostics
beep
tone
Second most recent
fault code is
displayed.
Repeat
beep
tone
Third most recent fault
code is displayed.
Repeat
beep
tone
Fourth most recent
fault code is
displayed.
Repeat
All indicators momentarily turn
off, then stay on.
DIAGNOSTIC: Console Buttons and
Indicators
Pressing buttons and rotating the cycle selector
will turn off the corresponding indicator and sound
a beep as shown in figure 1, page 2.
Pressing MORE TIME will toggle the left digit
and colon on the display while sounding a
beep.
Pressing LESS TIME will toggle the right two
digits on the display while sounding a beep.
Electric Models Only: Pressing the Wrinkle
Prevent button will activate the Inlet Air Flow
Test. See DIAGNOSTIC: Displaying Inlet Air
Flow, page 2.
Pressing the Cycle Signal button will
activate the Line Voltage Test. See
DIAGNOSTIC: Displaying Line Voltage,
page 2.
If indicators fail to come on and beep after
pressing buttons and rotating the cycle
selector, go to TEST #6, page 8.
DIAGNOSTIC: Door Switch
Opening the door should cause a beep and an
alphanumeric number (such as
) to be
displayed. Closing the door should cause a beep
and
to be displayed.
If opening the door fails to cause a beep
and a number and letter to be displayed,
go to TEST #7, page 9.
NOTE:
Opening the door while in Diagnostic Test
Mode may not activate the drum light. The light
will come on when Start is pressed, or upon
opening the door after the Diagnostic Test Mode
has been canceled.
DIAGNOSTIC: Moisture Sensor
Open the door and locate two metal strips on the
inside of the dryer. Using a wet cloth or one finger,
jointly touch both strips.
If a continuous beep tone is heard and an
alphanumeric number is displayed on the
console, the sensor is OK.
If a continuous beep tone is not heard, or if a
continuous beep tone is heard before touching
both moisture strips, go to TEST #5, page 8.
DIAGNOSTIC: Motor, Heater, and
Console ID
Close the door. Press the Start button. The motor
and heater will turn on. Continuing to press the
Start button will display the project codes and
software revisions. These codes are not relevant
to the service of the machine and can be ignored.
NOTE:
The console buttons only control the
indicator lights in Diagnostic Test Mode. When the
buttons are pressed, the corresponding features
will not be activated.
If the motor does not turn on, go to TEST #3,
page 5.
If no heat is detected, go to TEST #4, page 6.
