Introduction 2001 Energy SxS models are being introduced in response to the requirement for more energyefficient refrigerators by mid year 2001, along with having feature and operation enhancements. The primary differences in this refrigeration system are the adaptive defrost system (see Pub. # 31-9062), control board, software, and control systems that operate independently in fresh food and freezer sections.

Normal Operating Characteristics That Are Different from Previous Models • Length of time the compressor has run since the last defrost cycle. • Icemaker auger rotates clockwise. • • Evaporator fan running, without compressor or condenser fan. Amount of time the defrost heaters were on in the last defrost cycle. • Adaptive Defrost is divided into 5 separate cycles. Those operations are: Post Dwell (Adaptive Defrost), compressor, and condenser fan on with evaporator fan off after defrost cycle.
into a continuous cool mode (pre-chill). During prechill, the freezer temperature may be driven below the set point. However, the fresh food temperature will be regulated by the damper. Pre-chill will last for 2 hours. These models do not have a defrost holdoff. Defrost Heater Operation (Adaptive Defrost) After 2 hours of pre-chill operation, the main control board turns off the compressor, condenser fan, and evaporator fan.
Hinge System and Door Closure Dispenser Lock When the dispenser system is locked, no dispenser command will be accepted. This includes the dispenser cradle and will prevent accidental dispensing that may be caused by children or pets. If a pad is pressed with the system locked, it will be acknowledged with 3 pulses of the LOCK LED accompanied by an audible tone.
Airflow (Cabinet Interior) “Jelly Roll” Condenser The freezer compartment is designed so that when the evaporator fan is operating, air is drawn into the bottom of the air tunnel and through the evaporator. The cold air is then pushed out into the top of the freezer. The fresh food compartment receives chilled air via an electronic damper positioned at the top, rear of the refrigerator between the freezer compartment and the fresh food compartment.
