into a continuous cool mode (pre-chill). During pre- chill, 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.

During defrost operation, the main control board monitors the evaporator temperature using evaporator thermistor inputs. The thermistor will terminate defrost heater operation in less than 45 minutes. Typical defrost time is 20-30 minutes. Maximum defrost cycle is 45 minutes with heater on, 5 minutes in dwell.

The defrost system is protected by a defrost safety thermostat (switch). The thermostat opens when the evaporator temperature raises to 140° F and closes when the evaporator temperature lowers to 110° F.

Dwell Period (Adaptive Defrost)

After defrost heater operation has been terminated by the main control board, a 5-minute dwell period occurs. During this period, the compressor, condenser fan, and the evaporator fan remain off. The remaining frost melting from the evaporator will continue to drip and drain so that prior to the cooling operation, the evaporator will be totally clear of any moisture. After the 5-minute dwell period, the unit goes into post dwell.

Post Dwell (Adaptive Defrost)

The post dwell period is designed to cool the evaporator before circulating air within the refrigerator. This prevents any residual heat on the evaporator from being distributed in the freezer. During this period, the compressor is on and the condenser fan is on, but the evaporator fan is off, and the damper is closed. Post dwell lasts 10 minutes on these models.

Liner Protection Mode

The liner protection mode will activate if either of the doors have been open for 3 minutes. This mode will start the evaporator fan and close the damper.

This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-minute door-open count begins when the door is opened. If 3 minutes elapse before the door is closed, the liner protection mode will become active. Once the door is closed, timer #1 resets and liner protection mode goes into standby. In standby, normal fan and damper operations resume and timer #2 begins a 3-minute door-closed count. If 3 minutes elapse without a door opening, liner protection mode will completely deactivate. If a door is opened within the timer #2 door-closed count, the remaining time in the door-closed count will be deducted from the timer #1 door-open count.

Dispensing Functions

The water, crushed ice, and cubed ice functions are controlled by the main control board. To select a function, press the appropriate pad on the dispenser. The LED will light to identify the selection.

To dispense the selected item, depress the dispenser cradle located in the dispenser recess. The solenoid and linkage assembly will open the ice chute door to dispense the ice. If cubed ice is selected, the crushed ice bypass solenoid will allow cubed ice to bypass the ice crusher. The ice chute door must remain open for 5 second after dispensing ceases. After this 5 second delay, the solenoid and linkage assembly will shut the ice chute door.

The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released.

Dispenser Light

The LIGHT pad turns the dispenser light on and off. When the light is turned off, it will fade out. The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released. The LIGHT pad will not turn off the light during dispense.
