The water is going through the filter to provide water to our dispenser but water is not going to our freezer unit to make ice. We are changing the filter as we just purchased the appliance used but do you think the hose is some how plugged or what else should be looked at before we call a repairman.
Answer Melinda, The first place to start is the water inlet valve W10408179 on the back of the refrigerator. It is a "dual" valve, one portion of the valve supplies water to the filter and the dispenser. The other portion supplies water directly to the ice maker 4317943 assembly. It is possible for one section of the valve to fail and not allow water to enter and pass through the system. There are other possibilities, but start with the valve, it's the more common issue for your complaint.
How do I replace item W10121138?
To replace the filter housing you will first turn off water supply. Once supply is turned off remove the rear cover of the refrigerator and remove the water valve. Disconnect the tubing from the water valve that goes to the filter housing, should be dark gray tube. To remove the tube you will push in on the ring around the tube and pull the tube out. Go to the front of the unit, take off the toe grill. Take the wire that is attached to the side of the housing loose. Remove the 5/16" screws that hold the housing in place. Pull the housing out and disconnect the tubing in the same manner as the tubing on the water valve. Reinstall in reverse.
