DIAGNOSTICS & TROUBLESHOOTING
For Service Technician Use Only
Diagnosc Guide
Before servicing, check the following:
nMake sure there is power at the wall outlet.
nMake sure control lock is not enabled.
nHas a household fuse blown or circuit breaker tripped? Was
a regular fuse used? Inform customer that a me-delay
fuse is required.
nIs dryer vent properly installed and clear of lint or
obstrucons?
nAll tests/checks should be made with a VOM (volt-
ohm-milliammeter) or DVM (digital-voltmeter) having a
sensivity of 20,000 Ω per volt DC or greater.
nResistance checks must be made with dryer unplugged or
power disconnected.
nIMPORTANT: Avoid using large diameter probes when
checking harness connectors as the probes may damage
the connectors upon inseron.
nCheck all harnesses and connecons before replacing
components. Look for connectors not fully seated, broken
or loose wires and terminals, pin inseron, or wires not
pressed into connectors far enough to engage metal barbs.
nA potenal cause of a control not funconing is corrosion
or contaminaon on connecons. Use an ohmmeter to
check for connuity across suspected connecons.
Service Diagnosc Mode
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 specic troubleshoong tests.
Acvang Service Diagnosc Mode
1. Be sure the dryer is in standby mode (plugged in with all
indicators o).
2. Select any three (3) buons (except POWER) and follow
the steps below, using the same buons (remember the
buons and the order that the buons were pressed):
Within 8 seconds,
• Press and Release the 1st selected buon,
• Press and Release the 2nd selected buon,
• Press and Release the 3rd selected buon;
• Repeat this 3 buon sequence 2 more mes.
3. If this test mode has been entered successfully, all
indicators on the console will be illuminated for 5 seconds
with “888” showing in the three-digit display and a tone
will sound. If there are no saved fault codes, all indicators
on the console will turn o, and only the seven segment
display will remain on.
NOTE: The Service Diagnosc mode will me out aer
10 minutes of user inacvity, or shut down if AC power is
removed from the dryer.
Unsuccessful Activation
If entry into diagnosc mode is unsuccessful, refer to the
following indicaons and acons:
Indicaon 1: None of the indicators or display turn on.
Acon: Select any cycle.
¾If indicators come on, try to change the funcon for the
three buons used to acvate the diagnosc test mode. If
any buon is unable to change the funcon, something is
faulty with the buon, and it will not be possible to enter
the diagnosc mode using that buon. Replace the user
interface and housing assembly.
¾If no indicators come on aer selecng the cycle, go to
TEST #1, ACU Power Check, page 3-6.
Indicaon 2: Console indicators begin ashing immediately.
Acon: If console indicators begin ashing on and o
immediately, replace the user interface.
Acvaon with Saved Fault Codes
If there is a saved fault code, it will be ashing in the display.
Review the Fault/Error Codes table on page 2-8 for the
recommended procedure. If there is no saved fault code,
“888” will be displayed.
• See “Acvang Service Diagnosc Mode” to acvate these buons. Make sure all of step 3 is complete before acvaon.

DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Make sure control lock is not enabled.
Has a household fuse blown or circuit breaker
tripped? Was a regular fuse used? Inform
customer that a time-delay fuse is required.

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 1per volt DC or greater.
Resistance checks must be made with
dryer unplugged or power disconnected.
IMPORTANT: Avoid using large
diameter probes when checking harness
connectors as the probes may damage
the connectors upon insertion.
Check all harnesses and connections
before replacing components. Look for
connectors not fully seated, broken or
loose wires and terminals, pin insertion,
or wires not pressed into connectors
far enough to engage metal barbs.
A potential cause of a control not
functioning is corrosion or contamination on
connections. Use an ohmmeter to check for
continuity across suspected connections.
SERVICE DIAGNOSTIC MODE
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 SERVICE DIAGNOSTIC MODE
1. Be sure the dryer is in standby mode
(plugged in with all indicators off).
2. Select any three (3) buttons (except
POWER) and follow the steps below, using
the same buttons (remember the buttons and
the order that the buttons were pressed):
Within 8 seconds,
•Press and Release the 1st selected button,
•Press and Release the 2nd selected button,
•Press and Release the 3rd selected button;
•Repeat this 3 button sequence 2 more times.
3. If this test mode has been entered
successfully, all indicators on the console
will be illuminated for 5 seconds with “”
showing in the three-digit display and a tone
will sound. If there are no saved fault codes,
all indicators on the console will turn off,
and only the seven segment display will
remain on.
NOTE: The Service Diagnostic mode will time
out after 10 minutes of user inactivity, or shut
down if AC power is removed from the dryer.
