Operation Function 9-1) Digital Panel 9-2) Temperature Control Function When the system power is initally engaged, the default set temperature are -2℉ for the freezer and 38℉ for the set refrigerator, respectively. The numbers shown on the digital display panel stand for the actual compartments temperatures. When the compartment temperatures go down, so do the numbers on the display panel, and finally they reach the set temperatures.
Operation Function 3) When you select Power Freeze and Power Cool together Each function works at the same time. The COMP and F-FAN run continuously and the R-FAN runs until 25℉ in the refrigerator. 4) Initial Power-On 4-1) When the freezer and the refrigerator temperatures are higher than 14℉ and 50℉, respectively, if Power Freeze is selected, then the R-FAN will be off. If Power Cool is selected, then the F-FAN will be off.
Operation Function 9-6) Forced Operation function (Power cool key + Refrigerator. Temp 8sec.) This function enables a pull-down mode, a defrost mode for the refrigerator only, a defrost mode rigerator at the same time, and a cancellation of this function. ● Press Power Freeze and Refrigerator Temp. buttons for 8 seconds simultameously to get in the ready mode for a forced operation. ● The display panel will return to normal after 15 seconds in the ready mode.
Operation Function 9-7) Power failure compensating function 1) When the freezer temperature is lower than 50℉, all functions on the display panel will be restored. 2) When the freezer temperature is higher than 50℉, all functions will be initialized. (2℉ for the freezer, 38℉ for the refrigerator, and Cubed for the Ice Type) 9-8) Exhibition Function l This function is for a display purpose on the floor of show room or store. 1) Mode ON/OFF 1-1) For the exhibition mode, press Power Freeze and Freezer Temp.

13. Safety Instructions on Service ●Unplug the refrigerator before making any repair or any replacement. Avoid the electric shock. ●Use the rated components on the replacement. Check the correct model number, rated voltage, rated current, operating temperature and so on. ●On repair, be sure that the wires such as harness are bundled tightly and are not exposed by water. Bundle wires tightly in order not to be detached by the external force.
Appendix Ⅰ(Reference for circuit diagnostics) Ref.1) Wire connector on the cabinet door. Ref. 2) How to check relay failure * Disconnect the wire connector from the main PCB CN70, 71 and measure the following items. 1. Measure the coil bisection of the relay and check whether it works. 2. Measure the apex bisection for open circuit.
Ref. 3) Check a load * Unplug the power cord and disconnect the connector from the main PCB CN70, 71 and measure the following: 1. Measure resistance between the terminals and check for malfunctioning of a load and wire connection.

Ref. 5) Check Door S/W (Refrigerator Bulb) 1. Open the door and check if the freezer lamp turns on. 2. Press the Door S/W and check if the freezer lamp turns off. 3. Close the freezer door and repeat 1 and 2 for refrigerator door. 4. If there is a problem, check lightbulb and door S/W. 5. Check wire connection. (Micom signal) 1. Check if CN30 ⑥ and ⑧ is 5V DC after closing the F·R doors. 2. Check if CN30 ⑥ is 0V DC when opening F door. Check if CN30 ⑧ is 0V DC when opening R door. 3.
