7-6. Power freeze and Power

Selected by additional quick freeze & refrigeration button.

The lamp of quick freeze and refrigeration circulated everytime it pushed.

No change of setting temperature occured during quick freeze and refrigeration selected.

Temperature of freezer and refrigerator can be re-setted while quick freeze and refrigeration operates.

1)Quick freeze

(1)Comp. and F-fan runs continuously for two and a half hours when quick freeze selected. ( one minute after selection )

(2)During quick freezing the refrigerator controlled by setted notch.

2)Quick refrigeration

(1)Comp. and R-fan runs until the temperature of refrigerator reaches -4˚C when quick refrigeration selected.

(2)After the temperature reaches -4˚C the ’HIGH’ notch runs for an hour and finish quick refrigeration.

(3)Unless the temperature of refrigerator reaches -4˚C within two and a half hours quick refrigeration stopped.

3)When quick freeze and refrigeration selected at the same time

(1)Each function applied at the same time. Quick freeze runs Comp. and F-fan for two and a half hours and quick refrigeration runs Comp. and R-fan for two and a half hours with no relation of each other.

7-7 Alarming

1) Button touch (”Ding-Dong” sound)

(1)Everytime the button pushed, the input confirmation, ”Ding-Dong”, sounds.

(2)Not sounds, if two keys are pushed at the same time or wrongly handled.

2)Door-Open warning (”Ding-Dong” sound)

(1)Two minutes after door opened, ten times of alarming sounds.

(2)If door opened continuously, ten times of alarming sounds with one minute cycle. (3)Alarming stopped just after door closed.

3)Forced operating and defrosting (”Beep” sound)

(1)If forced function selected the ”beep” sounds.

(2)Alarming sounds untill the forced operating canceled by automatically ( 24Hr ) or manualy.

(3)Alarming sounds untill the forced defrosting canceled by automatically ( 24Hr ) or manualy.

Samsung Electronics

7-8 Defrosting

1)From the first power on, defrosting started after 4 hours of total Comp on time.

2)After that defrosting cycle can be varied from 6 hours to 32hours. (Comp on time)

7-9 Testing

Testing is for PCB, product, function and service.

After testing, turn the power on to start self diagnosis.

1)Forced operating

(1)As the button on PCB pushed once, Comp starts immediately without 5 minutes delay.

(2)If forced operating selected the notch of freezer and refrigerator fixed to ”HIGH” and ”MIDHIGH”. Then Comp and F-fan is controlled to pull-down and R-fan is controlled to ”MID-HIGH” notch.

(3)Pull-down maintained just for 24 hours during forced operating, after that automatically defrost freezer and refrigerator and then starts normal operating.

(4)Turn the power off or select test cancel mode to cancel the forced operating.

(5)Alarming (0.25 sec on/0.75 sec off) continues until the forced operating finished. It continues without any relations to alarming key selection or cancel.

2)Forced defrosting

(1)Push the test button one more time to run the forced defrosting of refrigerator.

(2)One more push in the above status will run defrosting of freezer and refrigerator simultaneously.

(3)Forced operating cancelled automatically by starting foced defrosting and return to normal operating after completion of defrosting.

3)Test cancel mode

(1)One more push in the status of forced defrosting of F/R will run normal operating.

(2)Alarming stopped in the test cancel mode.

7-10 Self diagnosis

1)Self diagnosis at first power on

(1)As the power applied to the refrigerator first time, all displays show and run the self diagnosis.

(2)If no problems founded display returns to normal model.

(3)If problem is founded, on and off the related display lamp and start alarming.

(4)Lamp displayed until the problem solved or self diagnosis cancelled.

(5)After problem solved the display mode return to normal.
