C. Defrost function
1) Defrost set up by time of COMP ON.
2) Defrost tun Heating →Rest time
3) When initial power on, initial defrost run defrost of freezer and refriger ator in 4 hours of COMP
ON. Since initial
(R →R, F →R →R, F ... Cycle operating))
4) ON/OFF of defrost - heater control by EVA-SENSOR If EVA-SENSOR is problem (short 10 pen),
it run just rest time and then finishes defrost function without heating.
5) During defrosting it maintain COMP and FAN state and after finish defrost-heating rest time
is 10 minutes.
6) Follows are defrost heating ON point and OFF point that operate by EVA-SENSOR.

D. TEST FUNCTION
▶TEST function is function for test,SVC and fair test of PCB and product.
▶TEST S/W choose and confirm function of product and then POWER ON to run self diagnosis.
1) FORCED OPERATING FUNCTION
●Pressed once TEST S/W on MAIN PCB. If so COMP and F-FAN run at once. Thus be careful because
occur COMP over load.
(Refrigerator FAN control ON/OFF by temperature)
●Since it set up forced operating function, it always run COMP and F-FAN and display lamp on MAIN
PCB with ON/OFF 0.1 second periodically.
(Refrigerator FAN control ON/OFF by temperature)
●In 24 hours forced operating function of freezer and refrigerator operate and finish then run normal mode
by KNOB position of temperature setting up.
●During forced operating function if you want to stop it first power OFF and then power on or choose
TEST cancellation mode.
2) Forced defrost function
●For forced operating pressed once TEST S/W button, it cancel forced operating at once and refrigerator
forced defrst function with display forced defrost position ON/OFF lamp on MAIN PCB 0.5 secoonds
periodically. If press one more TEST S/W bueeon display refrigerator and freezer defrosting.
●If forced defrost choose, COMP and FAN power OFF and defrost heater on at once, At this time,
if sensing temperature of EVA-SENSOR over 12℃defost heater power off and operate rest time normal mode.
●After heating finish it need 10 minal mode
3) TEST FUNCTION CANNCELLATION MODE
●Duting refrigerator and freezer run forced defrost function press one more TEST S/W button if so forced
defrost cancel and rest in 10 minutes and then turn normal mode.
