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? 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 Ω per 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 "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 momentarily
turn off, and then only the seven segment
display will come back on and display "888".
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.
