Operation Function 9-1) Digital Panel for RS253BA for RS255BA RS257BA 9-2) Temperature Control Function When the system power is initally engaged, the default set temperature are -4℉ for the freezer and 38℉ for the set refrigerator, respectively. The numbers shown on the digital display panel stand for the actual compartments temperatures.
Operation Function 9-3) Power Freeze and Power Cool Functions Select the Power Freeze or Power Cool buttons separately. These buttons are toggled ON and OFF and the indicators as well. Although you select Power Freeze or Power Cool, the set temperatures in the freezer and refrigerator are not changed.
Operation Function 9-5) Ice & Water Dispenser Function Among several ice-maker functions, the ice extraction function is performed by mechanical system. Only the relay control for a cubed-ice dispensing and the SSR control for the ice chute door are performed electronically. 1) Select Cubed/Crushed/Ice-off function 1-1) The Ice Type button selects Cubed/Crushed/Ice-off options in sequence.
Operation Function 1) Select function 1-1) Using Select button, Cool, Chill(30℉), and Soft Freeze(23℉) options can be selected in sequence. Cool option maintains a set temperature of the refrigerator. 2) Quick Cool function 2-1) If the Quick Cool is selected, LEDs will flash 60 and Min. The count will be decreased in every minute. 2-2) To cancel this function, press Quick Cool button again or Thaw button or Select button.

(If the back of bucket touches the guide-ice of ice maker, the ice maker will not make ice any more because of a ice full signal.) 2-3) It takes 6 hours to harvest a first ice, and throw away 2-3 times of these ice to make sure the supplied water clean.
Operation Function 5) Ice off function 5-1) When the Ice off operation is selected by Ice Type button, the ice making process will cease. 5-2) When the ice making process ceases, the final state will be the ice tray with supplied water. 5-3) When Cubed or Crushed operation is selected again, the control board will check an accumulated time period.
Operation Function 9-11) Forced Operation Function (Pull-down / Refrigerator Defrost / Refrigerator . Freezer-Defrost / Cancellation) This function enables a pull-down mode, a defrost mode for the refrigerator only, a defrost mode for the freezer and the refrigerator at the same time, and a cancellation of this function. Press Power Freeze and Fridge Temp.
Operation Function 9-12) Sound Function 1) Sound function 1-1) To make sure a command input, whenever a button is pressed, a “ding-dong” sounds. 1-2) When two or more buttons are pressed simultaneously or if a wrong button is pressed, there is no sound. 2) Door Open Alarm 2-1) When the doors remain open for 2 minutes, there are 10 times beeps.
Operation Function 9-15) Load Operation Check Function 1) In the normal operation, press Power Freeze and Power Cool buttons simultaneously for 6 second, then the display panel will blink for 2 seconds. 2) Press Fridge Temp. button ⓐ to get into this check mode with an audible tone. 3) Each illuminating LCD segment stands for the component which has an ouput signal from the control board.
Operation Function 1) Initially, all products set the code, “0” 2) After 20 seconds from adjustment, a new setting will be stored in EEPROM and return to the normal display. 3) Freezer Temp, Fridge Temp., Ice maker water supply, Ice tray temperature, and CoolSelect Zone temperature can be adjusted with this function.
