Cool Down
The time-based cool down time for automatic cycles varies from two to ten min-
utes, depending on the load size, moisture content, and dryness level selected.
For timed cycles, the cool down time depends on the total drying time the user
selects.
Wrinkle Shield
The WRINKLE SHIELD action tumbles the load without heat for 10 seconds of
every 5 minutes after the drying cycle is complete. WRINKLE SHIELD will con-
tinue for a maximum of 120 minutes (2 hours). If the door is opened and the
PAUSE/CANCEL key is pressed once, the control will enter the pause mode and
pressing the START key with the door closed will restart the WRINKLE SHIELD
operation. If the 120 minute time limit expires, the WRINKLE SHIELD action termi-
nates, the CYCLE SIGNAL is then sounded, (if selected), and the control removes
power from the motor and LEDs. Pressing the WRINKLE SHIELD key while in
WRINKLE SHIELD mode also terminates WRINKLE SHIELD. In essence, dese-
lecting WRINKLE SHIELD after the main cycle has completed simply turns the
dryer off.
SALES DEMONSTRATION MODE
The “Sales Demonstration Mode” allows sales personnel to quickly demonstrate
the cycles and options on the sales floor. The mode consists of an embedded
software routine which resides in the main dryer program which is defined as fol-
lows:
1. Open the dryer door.
2. Press the Touch Up cycle.
3. Select Air Only temperature.
4. Press Wrinkle Shield.
5. Press Start.
The sequence of operation is as follows:
• The Sensing LED turns on for 5 seconds and then turns off.
• The Wet LED turns on for 5 seconds and then turns off.
• The Damp LED turns on for 5 seconds and then turns off.
• The Drying & Cool Down LED turns on for 5 seconds and then turns off.
• The Cycle Complete and Wrinkle Shield LEDs turn on, and the End-Of-Cycle
signal sounds at the selected level.
Terminate the Sales Demonstration mode by pressing the Stop/Cancel keypad.

COMPONENT TESTING & DIAGNOSIS
SERVICE DIAGNOSTIC TESTS
The control must be in the STANDBY state before pressing the keypads to initiate the
diagnostic tests. To start the test routine, press the following keypads, in sequence,
within 5 seconds:
1. More Time
2. Less Time
3. More Time
4. Less Time
Once in the diagnostics, the following events will occur:
• All the LEDs will turn on and “88 ” will appear on the display. If the model identi-
fier diodes in the keyswitch do not match the configurations in the Model Identi-
fiers Table, an E3 error message will appear on the display. Make sure the cor-
rect control board is installed before continuing.
• Pressing the corresponding keys will turn off each LED and sound a beep (vol-
ume is Loud).
• When opening the door, the dryer will beep and the display will show a number,
followed by a capital “E” for electric or lower case “g” for gas. The first number
will be 7 for Whirlpool models.
• Open the door. Each actuation of the door switch will sound a beep.
• Short the moisture strips. The dryer will beep and the display will show a 2-
digit software revision code.
• Press the Start key. The heater and motor turn on, and the display reads a 2-
digit project identification code. The code for this project is “00”.
• Press the Stop/Cancel key to exit the diagnostics.

ERROR CODES
DISPLAY
PF (Power Failure)
EXPLANATION
If the household power goes off and the control was in RUN mode or
PAUSE mode, the electronic control board will display a power failure
error code.
To resume operation from where the last cycle was interrupted, press
the START keypad.
To switch to STANDBY mode, press the STOP/CANCEL keypad.
The dryer will not run if the exhaust temperature drops below 18˚F
or exceeds 250˚F.
(Thermistor Failure)
E1
When the thermistor circuit is open (>50K Ω), the error code E1 flashes
in the display.
E2
When the thermistor circuit is shorted (<500 Ω), the error code E2
flashes in the display.
NOTE: During a cycle, if the error condition is detected, the control delays action
one (1) minute for the start of the cycle to allow temperatures to get into the
allowable range. During diagnostics, the error is displayed immediately. If the
START keypad is pressed, an invalid tone will sound, and the dryer will remain
in PROGRAM mode. The dryer will not start until the failed thermistor is replaced.
Flashes when there is a keyswitch or software mismatch. NOTE: This error code
is displayed only in the diagnostics mode.

Long Vent Dryer Model LE/GV4634J
The Long Vent Dryer uses technology similar to the “Easy Clean 100 Lint Storage
Dryer.” A pulley and belt attached to the end of the drive motor (see the photo be-
low) steps up the speed of the blower to twice the standard speed. This increases
the air pressure in the exhaust to allow for substantially longer exhaust vent
lengths. The chart below shows the relation of the duct length to the number of
bends.

To maintain the current volume of air, (150 CFM), an air flow controller has been
added to the outlet of the lint chute (see the photo).
