Hi. I know this is an old thread, but looks like same issue I am having. The fridge is model # LRFC21760ST. The molded reservoir is leaking and I received the tubing style as a replacement. It does not fit. I saw the service bulletin that was attached to the thread in the link above. Not the same model number, but I assume it applies. Can someone confirm, is there an updated bulletin? Also, I assume there are two valves controlling water going to the dispenser that's why I can remove the valve in the door?
Also, the replacement part I received is part number 4838JA2002B.
