Product review (5 stars): This is the correct part for my 2006 LG LSC27950SW refrigerator, even though LG calls for 5221JA2006D (which won't work)
This is the part that fits my 2006 LG LSC27950SW refrigerator, although most parts sites showed I would need a different part (5221JA2006D).  The correct part has 4 sets of terminal connections, which is what my refrigerator requires (the incorrect part only has 3 sets of connections).  The blue sticker on each of the 2 sets of solenoids shows a distinct part number (neither of which is 5221JB2006A).  The part number on the solenoids with the green water tube fitting in the picture of this part matched my old part.  The part number on the section of solenoids with the 3 water tube fittings (orange, white, and dark gray in the picture) was different than the part number on the refrigerator's original part.  However, the ice and water worked properly using the new part, so the part number change didn't seem to matter.  I tested the old part after removing it (which wasn't easy because of the tight fit to get my hand into the back compartment to disconnect and reconnect the four water tubes), and found one of the 4 solenoids to be defective (zero resistance) using a multimeter.  Great to have water in the door again.  While making this repair, I also replaced both water lines on the back of the unit that go to/from the water filter, because one of them had previously failed.  Removing the water filter housing, to access the other end of these water lines, was tricky.
