LED/Switch Check
While in Service Mode, pressing the Chime and Wrinkle
Prevent keys for 3 seconds, will start a LED/Switch Test.
To exit the test at any point, press the same keys again
for 3 seconds or press the OFF key to exit Service
Mode.
Perform the check by pressing the keys which toggle the
LED’s on and off.
All switch pads must be pressed within 5 minutes for this
test to pass. PA will be displayed for five (5) seconds
once all switch pads have been pressed and this test is
completed. Following 10 seconds of inactivity at any
point, the test will exit without any display. The
Power
Off
switch pad must be pressed twice within thirty (30)
seconds to cancel this test.
Switch Action
Wrinkle Prevent Press once
Chime Press twice
Adjust Time Press once
Time Press four times
Temperature Press three times
Dryness Level Press four times
Selector Knob Rotate 1 position
Start Pause Press once
Off Press once
Diagnostic Codes
The Diagnostic Codes are identified when the severity
level of the abnormality detected is higher and service
may be required.
When a problem with the dryer is detected a Diagnostic
Code is assigned, and can be displayed. The Control
Board will not log multiple same codes per cycle;
however, it will log as many Diagnostics as possible for
the machine to continue running.
Access Diagnostic Codes by entering the Service Mode
and pressing Wrinkle Prevent. A d will be displayed.
Rotate the Cycle Selector Knob in either direction to step
through the list of codes one code at a time. Once an
initial direction is selected by the user (either Clockwise
or Counterclockwise), subsequent movements of the
knob in the same direction will show older codes. If the
user changes direction and turns the knob in the
opposite direction, the more recent code will be
displayed.
While a diagnostic code is displayed, if the Start/Pause
button in the center of the Rotary Cycle Selector is
pressed and held, the machine will display the number of
cycles ago the diagnostic code occurred. When the
Start/Pause button is released, the diagnostic code is
again displayed.
Clearing Diagnostic Codes
To clear the diagnostic code list press the
Sensor Dry
Level
and
Time
keypads together for 3 seconds while
viewing the list. The cycle count for each diagnostic code
will be reset to 0, but not the machine cycle count.
Diagnostic Codes
Code Description Trigger Action Taken
1
Dryer
Thermistor
Short Sensed
The
Thermistor
resistance is
very low.
Check for
:
- Clogged lint
screen.
- Restricted vent
system.
- Check Thermistor
resistance.
2
Thermistor
Open Sensed
The
Thermistor
resistance is
very high
Check for
:
Low ambient
temperature in
room (Below
-22
°F/-30°C).
- Outside vent
damper is stuck
open in
wintertime.
- Loose or open
wire terminals.
- Check Thermistor
resistance.
3
Door Circuit
Failure
Invalid state
for more
than 256
milliseconds
Check for
:
- Loose or open
wire terminals in
Door Sense
circuit.
4
Possible motor
transistor error
If either
motor
transistor is
seen open
or shorted
during
startup
Check for
:
- Loose
connections in
motor circuit.
- Run System
Check Mode and
check the motor
relay function.
- If relay functions,
disregard the
diagnostic code.
- If relay does not
function, replace
machine control
board.
