ASSEMBLY & DISASSEMBLY

Unplug the refrigerator before cleaning and making repairs. Remove any foreign matter or dust from the power plug pins.- Otherwise there is a risk of fire.

Do not use a cord that shows cracks or abrasion damage along its length or at either end. Do not plug several appliances into the same multiple power board. The refrigerator should always be

plugged into its own individual electrical which has a voltage rating that matched the rating plate.- This provides the best performance and also prevents overloading house wiring circuits, which couldcause a fire hazard from overheated wires.

Do not install the refrigerator in a damp place or place where it may come in contact with water.- Deteriorated insulation of electrical parts may cause an electric shock or fire.

The refrigerator must be grounded.- You must ground the refrigerator to prevent any power leakages or electric shocks caused by currentleakage from the refrigerator.

Do not put bottles or glass containers in the freezer.- When the contents freeze, the glass may break and cause personal injury.

Do not store volatile or flammable substances in the refrigerator.- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may causeexplosions.

1) If Energy Saver Key + Freezer/Power Freeze are pressed simultaneously for 3 seconds duringnormal operation, show room mode will be started with buzzer sound(ding-dong).

2) If above Energy Saver Key + Freeze/Power Freeze are pressed one more time, show roommode will be canceled.

3) If show room mode is selected, blinks "OF-OF" on the temperature setting display of the paneland it indicates the refrigerator has entered the show room mode.

4) During show room mode, if fresh food and freezer compartments sensors are higher than149(65) show room mode will be canceled automatically and freezing operation will bereturned.(There is no buzzer sound when the show room mode is canceled by the temperature)

5) Operation contents of show room mode- Display, Fan motor and etc operate normally, not to operate compressor only.- Defrost is not operated. (including french heater)- Display function of the initial real temperature is finished.- Under the condition of show room mode, show room mode will be operated when Power Onafter Power OFF.

If Energy Saver Key + Power Freeze Key are pressed for 3 seconds, show roommode will be started.


4-1-6. Option setting function If Freezer/Power Freeze Key+ Alarm/lighting Key are pressed simultaneously for 12 seconds

during normal operation, fresh food and freezer compartments temperature display will bechanged to option setting mode.

TROUBLESHOOTING

1) For example, if you want to change freezer compartment standard temperature to 28.4(-2C) by operating option, do as below.This function is for changing the standard temperature.In -2(-19C) of current temperature of freezer compartment, if you make the temperaturelower to 28.4(-2C) by the option, the standard temperature would be controlled -6(-21C)Therefore, if you change the setting of temperature option to -2(-19C) on the panel, theappliance will be operated with -6(-21C).It means that standard temperature is controlled 28.4(-2C) less than setting temperature inthe display.

If the display changes to option setting mode, all displays will be off except freezer andfridge compartments temperature display as below.(Fresh food and freezer compartments case will be explained only because all optionsare operated with the same method according to the option table.)

TROUBLESHOOTING

2) After changing to the option mode, fresh food compartment "0" , freezer compartment"0" will be displayed. ( Basically fresh food compartment "0", freezer "0" would be set atshipping process, but setting value could be changed for the purpose of improvingproduct at mass producing process.)- If fresh food compartment "0" shows only, temperature reference value of freezer

compartment will be set and current freezer compartment temperature code will bedisplayed on the freezer temperature display.

3) If freezer compartment "4" is set as below freezer compartment code after fresh foodcompartment "0 is set, standard temperature of freezer compartment will be lower than28.4(-2.0C).(Refer to the picture "changing the freezer compartment temperature")

: If you wait for 20 seconds after completing the setting, MICOM will save the setting valueto the EEPROM and normal display will be returned and the option setting mode will becanceled.

4) Option changing method as above is the same as all RF266/265** model.5) By the same method as above, it is possible to control the fresh food compartment

temperature, water supply, ice-maker harvest temperature/time, defrost return time,hysteresis by temperature, notch gap by temperature etc.

6) Option function is set in the EEPROM at shipping process in the factory.You would better not to change the option of your own.Completing the setting is that option function return to normal display after 20 seconds.Do not turn off the appliance before returning to the normal display mode.

Reference ValueCode


Option setting function exists in the other items.We will skip the explanation of the other functions by the option because it isassociated with refrigerator control function and is not needed at SERVICE.(Please do not set the other options except above SERVICE Manual.)NOTE

pulse when motor fan operates.

CN75-5(F),6(R),7(C)will generate the pulse signal when motor rotates.These signals will be inputted into MICOM.Unless signals are not inputted during motor operating, will be ON 10seconds after fan Off. But if signals are not still entered, the above operationwill restart four times more.If signals are not entered continuously, the motor will be restarted after 10seconds.This function is effective when the normal operation of motor would berestrained by foreign matters such as ice.

CN76 #2 will generate the pulse signal when motor rotates.These signals will be input into MICOM.Unless signals are not input during motor operating, will be ON10seconds after fan OFF. But if signals are not still taken, theabove operation will be retried four times more. If signals are nottaken continuously, the motor will be restarted after 10 minutes.This function is against the case that motor movement would berestrained by foreign matters like ice.

TROUBLESHOOTING

1. Water is automatically supplied to the Ice Maker by temperature & time and Ice Maker Dispenses cubed orcrushed ice.

2. Power is applied to the one end of wires. Be careful when disassembling and shall refer to its exploded diagramin any case.

3. Ice Maker operation shall be checked after pressing the Ice Maker testing switch.(Freezer Ice Maker) It is not possible to check when the power is disengaged.

4. We recommend that TWO PEOPLE check the PCB and Ice Maker because hey are located at front and rearside each.

5. Be careful! The Ice Maker Heater can cause personal injury like burn.
