New Version of
Blower Housing, it
may be necessary to
separate the harness
wrap on replacement
housing. Please
maintain shielding
on the low voltage
wires.
Sensor Bar Touch Data Mode
How to Enter:
Power on dryer, open door and press in door switch.
Start dryer tumbling. Press Temp + Signal for 3 sec.
Touch both sensor bars with wet cloth, sensor hit numbers
show in display.
Note: Test mode subject to change without notice
Cycle Count Test Mode
How to Enter:
Press Temp + Signal Keys for 3 sec during Power On
State.
Press Signal for 3 seconds (until beep)
Note: Test mode subject to change without notice
Software Version Test Mode
How to Enter:
Press Temp + Signal Keys Keys for 3 sec during Power
On State. Press
Temp key for 3 seconds (until beep)
Note: Test mode subject to change without notice
Temperature Test Diagnostic Mode
How to Enter:
Press Adjust Time Up + Down Keys for 3 sec during
Power On State.
Press Adjust Time Up and it will display the temperature
in Celsius.
Compare vent temp to drum temp to see air flow.
This can be with just power on or dryer running.
Gas Valve Testing
Unplug connectors and test valve terminals
(its numbering is from the front terminal.)
Check across terminals #1 and #3 (Booster Coil). 550 Ω
Check across terminals #1 and #2 (Holding Coil). 1350 Ω
Check across terminals #2 and #3 (Both coils in series). 1900 Ω
Check across terminals #4 and #5 (Secondary Coil). 1300 Ω
Dryer continues to run after cycle completed
Wrinkle Prevent option provides approximately 90 minutes (20 continuous and 70 intermittent) of tumbling in
unheated air at the end of the cycle to reduce wrinkling. Press the Wrinkle Prevent button to activate or deac-
tivate this feature. The indicator light above the pad will illuminate when Wrinkle Prevent is selected. Chasing
lights appear in the display when the Wrinkle Prevent option is selected. The load is dry, and can be removed
at any time during the Wrinkle Prevent cycle.
SUBJECT: Dryer belt slides off the pulley when
manually rotated counter-clockwise (ccw)
SYMPTOM: The dryer drum will not turn. On occa-
sions, the customer will rotate the drum counter
clockwise (CCW) to check for any remaining
clothes left in the dryer drum. By rotating the drum
CCW, the idler arm may shift causing the belt to
slide off the pulley.
SOLUTION: To prevent the dryer belt from sliding
off the pulley, the pulley has been redesigned.
The Outside Diameter has been changed from
22mm to 27mm.

Make sure the idler pulley & the motor pulley are in
a straight line, bend if needed
RY6CN6
Testing Electric Heater circuit.
Disconnect Blue wire from RY6, turn power on, start dryer read voltage between RY6 Blue wire and CN6
Green wire.
Reading of 120VAC means a proper operating heater circuit. 0VAC means open in circuit.
To test thermostats use ohm meter on lowest scale, any resistance replace component
See page 4 for Main PCB layout for testing.
RY 6 RY 5
RY 5 CN7
Testing Main PCB power output to Heating
& Motor circuit.
With motor running in the heating mode,
read AC voltage across RY6 and RY5.
Any voltage reading means Main PCB is
defective.
See page 4 for Main PCB layout for testing.
Testing Motor circuit.
With power off read
resistance between
RY5 Brown and CN7
Blue.
Resistance reading of
good motor circuit is
about 1.9Ω. To test
thermostat and switch
use ohm meter on
lowest scale, any
resistance replace
component.
See page 4 for Main
PCB layout for testing.
