Product review (3 stars): Factory part, was missing a switch, but I made it work
The valve arrived promptly in sealed whirlpool factory certified parts container.
The part fit perfect and works better than the original part did.  Better water flow and better temperature control of the water. The only drawback was that the ORANGE COLORED plastic receptacle and temperature switch (as shown in the picture) were absent from the new part that I received.
Fortunately my problem was a solenoid issue and not a temperature issue. I simply took the old ORANGE receptacle and switch from the old valve and installed it in the new valve.
Since the part was sealed in factory container, I would say that the missing part was an over site by whirlpool and not amazon.
