Product review (5 stars): Direct replacement part for LG LSC27914SB
I have a LG LSC27914SB.  The water dispenser slowly dispensed water at a trickle over time.  Also, it seemed it wasn't making ice as quickly.  I live in AZ, where we have really hard water, so I tried changing the water filter, to no avail.  Used this part, and now it works perfectly.  It was a direct replacement for the existing one.  I just had to remove the "locks" on the push connects on the old part and swap them over.  The Amazon "Does this part fit" wasn't sure if it would work, if you have my model fridge, it will.
