Function test sequence
This is a functional test for the dryer. To activate this
mode, perform the following steps:
1. Turn the cycle selector knob to the 12 o’clock posi-
tion.
2. Press and hold the Select and Pause Cancel
buttons simultaneously for (6) seconds.
3. Immediately after, press andholdthe Pause Cancel
and START buttons for (4) seconds.
The control will enter the test mode, the buzzer will
sound 3 times and all LED’s will rapidly flash.
After entering the test mode, the selector can now be
rotated to select the following test.
Rotate program knob clockwise from the start position:
1 Turn Drive motor runs, heat source is on.
Drying LED is lit. Control thermistor
reading is displayed. **
2 Turns Drive motor runs; heat source is off.
Cool Down LED is lit.
3 Turns Drive motor runs; heat source is off.
Drying and Cool Down LED’s are lit.
The MORE DRY LED should be ON.
Opening the door (press in on door
switch plunger) and placing a finger
on both moisture sense bars at the
same time will make the DAMP LED
come on.
4 Turns Drive motor runs; heat source is off.
a. When the TEMPERATURE selec-
tor is rotated, there should be a
key beep with each setting.
QUICK REFERENCE SHEET
b. WhentheDRYNESS key is pressed,
all the dryness level LEDs should
light.
c. When the OPTIONS or Select key
is pressed, all the options LEDS
should light.
d. When the START key is pressed,
all the cycle status LEDs should
light.
e. When the Pause Cancel key is
pressed, all the cycle status LEDs
should light.
5 Turns Drive motor runs; heat source is off.
Cool Down LED is lit. Control ther-
mistor reading is displayed. **
6 Turns Drive motor runs; heat source is on.
Drying LED is lit. Control thermistor
reading is displayed. **
To EXIT test mode, press and hold the Select and
Pause Cancel buttons simultaneously for six seconds
or disconnect power from dryer. Dryer will be reset
for regular operation.
**The dryness LED’s are used to determine the
control thermistor reading. The number of flashes
of the bottom three LEDs will determine the value
of the temperature as follows.
NORMAL = HUNDRED’S
LESS DRY = TEN’S
DAMP = ONE’S
Example: Normal flashes 1 time
Less Dry flashes 2 times
Damp flashes 6 times
Temperature = 126 degrees.
