Overview
General
The GE Profile Harmony Dryer is part of the GE Profile
Harmony Clothes Care System utilizing the latest
developments in dryer technology.
Most conventional drying systems have a single motor
that powers both the blower and the drum. Therefore,
the blower fan and dryer drum are powered at the same
rate of speed. If air flow is impeded by lint buildup or
lengthy venting, the dryer cannot increase the fan
speed without increasing the drum speed. The
Harmony Dryer System utilizes dual motors and
strategically placed sensors. This enables the dryer to
respond quickly to temperature changes and ensure
proper air flow to optimize drying effectiveness.
Other features include:
Communication Link to the Washer- The dryer uses a
serial cable to automatically receive information from
the washer about the nature of the wash load,
essentially presetting the dryer controls so the user
doesn’t have to.
Dual Motors - The dryer is equipped with dual motors -
one dedicated to the drum, the other to the blower fan.
The addition of a dedicated blower motor enables the dryer to alter fan speed whenever necessary to
optimize air flow. This capability greatly increases drying performance and efficiency. (See Drive Motor
and Blower Motor).
Variable Heater - The dryer's heater is capable of variable heat output. Its voltage regulation feature
allows the system to be rated at 6000 watts.
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. The sensors work together with the
variable heater and blower to provide consistent even heat. (See Inlet Thermistor.)
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.

SENDING INFO TO DRYER... RECEIVING...
Washer
Communicated
Cycles
If the Washer/Dryer Communication features
of your washer and dryer are turned ON, your
dryer will receive cycle information from your
washer to create a dry cycle that matches your
wash load.
After the wash cycle is complete,
communication begins once either the washer
or dryer Touch Screen is activated.
Once the information is received, your dryer
can then create the optimal dry cycle for your
load. You can then change any of the
automatic cycles, as desired.
NOTE: For some communicated wash cycles,
your dryer will prompt you to select a FABRIC
TYPE.

Instructions for attaching the serial cable for
