Tools and Supplies Needed

Gather the following tools and supplies before beginning this repair:

• Phillips head screwdriver
• Flat head screwdriver
• 3/8″ open-end wrench
• New OEM water line tubing (5210JA3005E)
• Towels or bucket

Turn off the water supply line connected to the refrigerator. Shut off power to the appliance by unplugging it or switching off the circuit breaker. Have some towels or a bucket ready to catch any water that may drip during the line replacement.

Removing the Old Water Line

With the refrigerator powered down and the water supply off, you’re ready to detach the old water line:

1. The water line runs from the back of the refrigerator to the dispenser area inside the door. We’ll first remove the access panel on the back.
2. Use a Phillips head screwdriver to remove the two screws securing the panel.
3. Take off the panel to expose the water line and connections.
4. Locate where the water line connects to the outlet side of the water filter.
5. Use a 3/8″ open-end wrench to loosen the compression nut on the 90-degree elbow fitting.
6. While holding in the release collar, detach the water line from the elbow.
7. Remove the single screw on the side hinge cover using a Phillips screwdriver.
8. Take off the cover to access where the water line enters the refrigerator cabinet.
9. Remove the tilting door bin inside the refrigerator. Insert a flathead screwdriver into the release tabs to detach it.
10. Set the bin aside to gain better access to the water valve area.
11. Take out the single screw securing the valve cover.
12. Drop down the valve and water tank assembly.
13. Use a flat-head screwdriver to pry out the release clip from the valve inlet.
14. Press the release collar on the line and detach it from the valve.

Installing the New Water Line

After removing all the old tubing, it’s time to install the replacement water line:

1. Insert the new tubing into the hole on top of the refrigerator door.
2. Feed the line down through the door, around the bottom, and back up to the valve inlet.
3. Push the line firmly into the valve inlet until fully seated.
4. Replace the locking clip to secure the connection.
5. Reattach the valve and water tank assembly with a single screw.
6. Replace the side hinge cover and Phillips screw.
7. Reinsert the tilting door bin, snapping it back into the locking tabs.
8. Attach the open end of the line to the outlet elbow fitting on the water filter.
9. Make sure the line is fully inserted and the locking collar snaps into place.

Checking for Leaks

With the new water line installed, restore power and water supply to the refrigerator. Open the dispenser valves and run a glass of water. Check all connections carefully for any drips or leaks. It may take a few minutes for the water to flow evenly as trapped air is purged. Monitor your refrigerator over the next day or two to ensure no leaks develop.
