Serial number 504KW00377, purchased new February 2006
My main control board is bad.
Local service company ordered part from LG - received similar control board, but would not work because two multipin connectors have been revised from three pin to two pin.
My control board is stamped with LG part # 6870ED9001A. Your part number AP443956 shows the LG part # 6870ED9001C if you look closely at the component side view.
The part brought yesterday by the service company was also a revison C, however the two (red & white) multipin connectors, shown in the upper right corner near the two blue modules, had been changed from three pins each to two pins each.
My machine needs the three pin version. Your rev C board shows the 3 pin connectors. Is this the right board? Why would there be two different versions of the rev C board?
ANSWER Hello Charles. Yes, based on the model number you provided, 6871DD1006F is the correct PCB assembly. Hope this helps.
