– 6 –OverviewGeneralThe GE Profile Harmony Dryer is part of the GE ProfileHarmony Clothes Care System utilizing the latestdevelopments in dryer technology.Most conventional drying systems have a single motorthat powers both the blower and the drum. Therefore,the blower fan and dryer drum are powered at the samerate of speed. If air flow is impeded by lint buildup orlengthy venting, the dryer cannot increase the fanspeed without increasing the drum speed. TheHarmony Dryer System utilizes dual motors andstrategically placed sensors. This enables the dryer torespond quickly to temperature changes and ensureproper air flow to optimize drying effectiveness.Other features include:Communication Link to the Washer- The dryer uses aserial cable to automatically receive information fromthe washer about the nature of the wash load,essentially presetting the dryer controls so the userdoesn’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 tooptimize air flow. This capability greatly increases drying performance and efficiency. (See Drive Motorand Blower Motor).Variable Heater - The dryer's heater is capable of variable heat output. Its voltage regulation featureallows the system to be rated at 6000 watts.Dual Thermistors - Thermistors are much more sensitive to temperature changes and can relay theinformation faster than thermostats. The dryer uses dual thermistors to monitor incoming airtemperature as well as the air temperature leaving the drum. The sensors work together with thevariable 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 andend the cycle at the desired moisture level. (See Moisture Sensor.)Plastic Top & Backsplash - The dryer top and backsplash have UV stabilizers to prevent yellowing whenexposed to sunlight.HELPBACKSTARTSTOPHOMEMYCYCLEPOWER
