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 s
