Product review (5 stars): Something to check before buying a new valve inlet.
This product works as expected, and is the correct model for my fridge.  It is possible however, that I did not need it.  My water dispenser made a strange noise, and dispensed almost no water.  The same was likely true for the ice maker.  I was not able to remove the upper panel, which is what I needed to do in order to replace the part (I was afraid of breaking something), so I called whirlpool for service.  The tech was at my house for about 10 minutes, and it cost me $230 for a service call and labor.  The tech asked if I had the bypass cap, which I was not sure where I placed it, since I had remodeled my kitchen after getting the fridge.  Long story short.  He took the (1 week old) filter out, put in a new one, and it worked.  For one day...  The next day I tried ordering a bypass cap, and then found that I stored mine in the door.  I took out the filter, and put in the cap, ran the water a little, replaced the filter, and now everything works better than ever.
