Product review (3 stars): Try & Try Again
Lasted a few wks. then kept popping out & had to put it back in & I'm the only person who uses the ref. water & ice.  Should have lasted a few mnths.  Green light in the ref. never turned red before it stopped working.  Also bought it directly from Whirlpool & had the same problem.  I then bought the three pack from Amazon.  The first filter lasted two wks. then kept popping out & the green light was on.  I tried the second filter in the pack & it has now worked for two mnths. w/the red light going on & in two wks. changed to green.  Not sure if it's the filter or the refrigerator which I bought in Mar. 2015.  Never had this problem w/the old Whirlpool ref.  Have one filter left.  Hopefully it works.
