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

and Blower Motor).

Drive Motor

V ariable Heater - The dryer's heater is capable of variable heat output. It s 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.

Quick Start

Getting Started

If the Touch Screen is dark, press POWER or the Touch Screen to access the dry cycles menu.

Clean the lint filter.

IMPORTANT: Clean the lint filter each time you use the dryer.

Add clothes. Do not overload. This wastes energy and promotes wrinkling.

Select one of the four drying methods from the Home Screen:

• Press BY FABRIC to dry according to fabric type.

• Press BY GARMENT to dry according to clothing type.

• Press SPECIAL CYCLES to dry nongarment items, to dry without heat or to dry using the drying rack.

• Press TIMED DRY to specify a drying time and temperature.

Change any of the automatic settings, if desired, by pressing the Touch Screen and following the on-screen instructions.

By changing the settings you can:

• Change the level of dryness

• Change the drying temperature

• Set a Delay Start or Extended Tumble, or change the End-of-Cycle Signal volume

• Adjust time settings

Close the door and press START.

The dryer will not operate unless the door is closed.

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.

See “Final Setup” in the Installation Instructions for attaching the serial cable for Washer/Dryer Communication.

Jumper Configurations

Jumper Plug

Note: The gas dryer main board differs from the electric dryer main board by the addition of a jumper plug on the model selector connector (the electric model has no jumper plug). Depending on how the pins have been jumped will determine what type of gas (natural or LP) the dryer is using.

The LP conversion kit is part number WE25X10014 and consists of the LP model selector and an LP orifice for the gas valve.

The dryer control performs three checks to determine whether the dryer is an electric, LP gas or natural gas.

• Initially , the control looks for a flame sensor. If the flame sensor is detected, the control then looks for a model selector set for natural or LP gas.

• If both conditions are satisfied, the dryer will start.

• The dryer control then monitors temperature based on specific software parameters for each type of gas. If the temperature is outside of that range, an error is displayed on the LCD display and the dryer will shut down. (See

Error Chart Gas Setup Failed).
