Product review (1 stars): Got it in one day, installed the new filter ...
Got it in one day, installed the new filter,  and no water is now flowing from the refrigerator...  I don't know why...  The old filter works.  So why won't this one?  I noticed that the item number I needed was UKF8001, and the one I got was WCF1801.  I'm wondering if it's incompatible for my refrigerator...

Continued...  Sears came out, and this product is and OLD version of the filter I need, there's also a size difference, which is significant to it's performance.  The filer head was not engaging the filter housing.  Totally Jacked up my fridge.  I have to replace the filter housing now also because of this.  I ended up spending $70 for Sears to come out to my home, and another $30 for the CORRECT filter, which is Model number EDR4RXD1.  Needless to say, this ended up costing more than it was worth!
