Product review (5 stars): Easy Fix
This part worked like a charm when my fridge stopped dispensing water (the water filter had always chattered for a few minutes whenever I changed filters, so I knew the water filter head was probably the culprit when my fridge completely stopped dispensing water.) I used Youtube to learn how to swap the heads and it was an easy fix.  Just make sure you confirm what part # you need through GE's website before ordering, and you should be good to go!
