Dryer - Heat Management Systems

GE Appliances has used various heat management systems on our Dryers over the years. Some heat management systems are no longer featured on our Dryers. The common heat management systems currently used on our Dryers are Sensor Dry and Automatic Temperature Control (ATC). You can search the model number for your Dryer on our GE Appliances website and check the product specifications to determine the heat management system featured on your specific model.

 

Understanding Various Heat Management Systems Used on a Dryer

DuoDry™

  • The GE Profile Harmony™ Dryer employs two motors, two thermistors, two moisture sensors and a variable heater to give you excellent drying performance.
  • The GE Profile Harmony™ Dryer monitors fabric dryness and temperature throughout the dry cycle. Once clothes are dry, adaptive cool down begins, the heat is turned off while fabrics continue to tumble until cool and that helps prevent wrinkling.

Perfect Dry with Dual Thermistors

  • This enhanced heat management system gives consumers even more control over dryness levels of clothes.
  • With Perfect Dry, traditional thermostat heat control has been replaced by a dual thermistor system that gives consumers more control of dryness levels and faster, more even drying performance.

Sensor Dry Plus / HE Sensor Dry

  • GE Appliances' most advanced heat management system, ever! Dries clothes 20% faster than the Sensor Dry system on past models.
  • The Sensor Dry Plus sensors are located in the front of the Dryer wall just as the past Sensor Dry system. What makes it more sensitive is that it is sensing every second as compared to every couple of minutes.
  • Dual thermistors precisely measure the temperature and help to maintain a more even heat and temperature inside the Dryer drum.

Sensor Dry

  • The electronic sensor Dryers contain a very accurate method for drying clothes. An electronic sensor board with moisture-sensing "fingers" actually touches the clothes every couple of minutes to determine their moisture content. The sensing system terminates the dry cycle when the clothes have reached approximately 2% moisture retention.
  • The Dryer will "cool down" and shut off automatically. Electronic sensor Dryers are less sensitive than other types of controls to changes in room temperature and humidity.
  • 25% more accurate and shorter than the ATC system.

Automatic Temperature Control (ATC)

  • The Automatic Temperature Control may increase the life of fabric by helping to prevent over-drying. The Automatic Temperature Control (ATC) system continuously senses the temperature of the air in the Dryer drum and determines the amount of time necessary to dry a load of clothes.
  • The heat will turn off and on throughout the cycle a number of times. This is normal.
  • The timer will advance intermittently, but will continue to advance until it turns the Dryer off automatically.
  • Total drying times will vary depending on the size of the load, the types of fabric and the amount of moisture in the clothing.

The MORE DRY setting allows the Dryer to remove the most moisture from the clothing. The LESS DRY setting indicates that a small amount of moisture is to be left in the clothing to help minimize wrinkling. OPTIMAL or OPTIMUM DRY should be used to dry the clothes without overdrying or leaving too much moisture in the clothes.

 

Note: The only difference between the Automatic Regular Cycle and the Automatic Permanent Press cycle is the cool down period at the end of the Permanent Press Cycle.
