TECH SHEET - DO NOT DISCARD
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
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
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? 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.

DIAGNOSTIC TESTS
These tests allow factory or 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 Pause/Cancel) and follow the steps
below, using the same button (remember the button):
Press/hold Release for
2-5 seconds 2-5 seconds
3. If this test mode has been entered successfully, all indicators on
the console are illuminated for 5 seconds with
Estimated Time Remaining two-digit display.
DIAGNOSTIC: Unsuccessful Entry
If entry into diagnostic mode is unsuccessful, press the Pause/Cancel
button twice, then press the Power button.
If indicators come on, try to use a different button than was used to
activate the diagnostic test mode. If that button fails to enter the
diagnostic mode, something is faulty, and it is not possible to enter
the diagnostic mode. Go to TEST #2, page 6.
If no indicators come on after pressing the Power button, go to
TEST #1, page 6.
DIAGNOSTIC: Saved Fault Codes
If there are saved fault codes, the most recent fault code will
alternately show "F-" and "XX" where XX is the fault code.
Press and release

DIAGNOSTIC: Console Buttons and Indicators
Pressing the console buttons or rotating the cycle selector will sound
a beep and will turn on or off the corresponding indicators as shown
in Figure 1, Console Diagnostics, page 2. Pressing Time Adjust
(more time) will sound a beep and turn the left digit of the display on
or off. Pressing Time Adjust
the right digit of the display on or off.
If indicators fail to turn on or off and beep after pressing
buttons or rotating the cycle selector, go to TEST #6, page 10.
DIAGNOSTIC: Door Switch
Opening the door should cause a beep and an alphanumeric number
to be displayed. Closing the door should cause a beep and
displayed.
If opening the door fails to cause a beep and a number and letter
to be displayed, go to TEST #7, page 10.
DIAGNOSTIC: Moisture Sensor
Open the door and locate two metal strips on the inside of the dryer.
Bridge these strips with a wet cloth or a finger.
If a continuous beep tone is heard and an alphanumeric number is
displayed on the console, the sensor is OK.
If not, or if a continuous beep tone is heard before bridging the
moisture strips, go to TEST #5, page 9.
