Reference

If the door is opened, the contact of door switch will be opened and MICOM will get applied 5V to finally sense Open.

If 5V has been sensed over tree minutes afterwards, Door-Open alarm will sound Ding-Dong for 10 seconds in a one minutes cycle.

For that reason, if the door switch has failure, the refrigerator can make a Ding-Dong sound with oneminute cycle. Please note the step for its service.

When measure lamp resistance to the Wire Resistance can be changed by Lamp input voltage. (Actual measurement is below, it can be changed by performance)

Checking method of Door Switch voltage

-Measuring voltage of CN30#2(Purple), CN30#1(black) and REG1, HEAT SINK from PCB typical Ground part
