Product review (5 stars): This part is an exact replacement for a Kitchen Aid ...
This part is an exact replacement for a Kitchen Aid part 2319734 and it fits properly on a model KSCS25FTMS02 refrigerator. It also matches the full Whirlpool part number WPW10159840. My water dispenser had completely stopped working and this was a straight forward fix that worked perfectly. Note you will have to run it for ~30sec before it will totally prime the line and start pumping water.
