Help! I took the advice of Gene. I replaced the dual water input valve. I still have the same problem. Ice maker is not making ice. Water dispenser works fine when filter is not in place and using the bypass cap instead. Once I attach the filter, the water stops coming out of the dispenser and a loud clicking sound comes from the refrigerator. (Seems to be coming from the back wall of the refrigerator near the filter input) This is the second filter I have had on in less than a year and this happens.
All of this was happening the same way before I replaced the dual input valve.
