Introduction
The GE Profile High-Efficiency Dryer is part of the GE Profile Clothes Care System, utilizing the latest
developments in dryer technology.
The Profile Dryer System utilizes strategically placed sensors. This enables the dryer to respond quickly to
temperature changes and ensures proper air flow to optimize drying effectiveness.
Other features include:
Dual Thermistors - Thermistors are much more sensitive to temperature changes and can relay the
information faster than thermostats. The dryer uses dual thermistors to monitor incoming air temperature,
as well as the air temperature leaving the drum.
Moisture Sensor - The moisture sensor allows the control to monitor the fabric for moisture content and end
the cycle at the desired moisture level. (See Moisture Sensor.)
Plastic Top & Backsplash - The dryer top and backsplash have UV stabilizers to prevent yellowing when
exposed to sunlight.

Cycle Options
Note: Not all features are available on all dryer models.
Wrinkle Care
Tumbles the drum without heat for 10
seconds every 5 minutes for up to 3 hours.
The dryer will display a “racetrack” on the
display during the Wrinkle Care phase.
Wrinkle care shuts off automatically when
the door is opened.
Signal
Alerts you that the cycle is complete.
The clothes should be removed when the
beeper goes off so wrinkles don’t set in.
Press SIGNAL to select low or high volume,
or to turn the beeper off.
The beeper will continue to sound every
2 minutes (maximum of 4 times).
MORE TIME
Increases the dry time in 1-minute
increments, up to 99 minutes.
LESS TIME
Decreases the dry time in 1-minute
increments, down to 10 minutes.
Lock
You can lock the controls to prevent any
selections from being made. Or you can lock
the controls after you have started a cycle.
Children cannot accidentally start the dryer
by touching pads with this option selected.
To lock the dryer, press and hold the DRY
LEVEL and TEMP buttons at the same time
for 3 seconds. To unlock the dryer, press and
hold the DRY LEVEL and TEMP buttons for
3 seconds.
When the lock function is enabled, CL will
blink in the display with the estimated time
remaining.
Estimated Time Remaining
Displays the approximate time remaining
until the end of the cycle.
As the cycle begins, you will see an initial
approximate total cycle time in the display.
Then lights will “race” in the display. This
means the dryer is continuously monitoring
the amount of moisture in the load. The lights
will continue until the dryer senses a low level
of moisture in the load. At that point, the
dryer will calculate and display the
approximate time remaining.
_________________________________________________________________________________________

settings and hold down the MY CYCLES
button for 3 seconds. A beep will sound to
indicate the cycle has been saved.
To use your custom cycle, press the MY
