• 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 ”MID-
HIGH”. 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
