Product review (5 stars): Not the easiest install but well worth the effort
Of the 5 or 6 water lines that I had to deal with my fridge had one that had less than 3 inches slack so I couldn't shorten it to make sure the new fitting sealed evenly. Not the fault of this part, just poor design from the factory.

I was surprised to see this part is rated for 40W. Apparently there is a very tiny electric motor inside the unit that pumps the water through. Not sure which module has the motor but the motor itself must be smaller than my thumb.

In our case we replaced the old part because of lime/calcium buildup which reduced the water flow to a trickle that would take several minutes to fill a cup. Very nice to be able to fill a glass in a few seconds again.
