Will replacing AJL72911507 fix the leak shown in LG LFX25973ST?

Brand: LG
Model Number: LFX25973ST
Main Symptom: Leak in water line
What happens & when:

There is a water droplet forming as shown in the attached image. Water from this leak pools on top of the freezer drawer below where the doors meet, and also on the floor on the left side of the refrigerator.

Pushing the hose into the fitting firmly does not fix the leak. I assume the problem is with the fitting. It looks like the fitting is part of AJL72911507. According to the listing on appliancepartpros.com, that part is not compatible with my refrigerator, but according to Arvin T. (appliancepartpros chat) and lgparts.com, it is compatible.

Does it look like replacing this part will fix the leak, and is that something I can probably do myself? Is there a better solution?

Thank you!

The water tank stores chilled water before it reaches the dispenser. If it’s leaking, cracked, frozen, or restricting water flow, replacing it is usually a straightforward repair. The AJL72911507 is the correct water tank assembly used in many LG French-door refrigerators, including the LFX25973ST series.

Helpful Technician Tip

After installation, it may take a few minutes of dispensing before the water stream becomes steady. If the original tank cracked because it froze, consider raising the refrigerator temperature setting slightly (around 37–39°F is typical) and check that cold air is not blowing directly onto the tank area.

The repair is usually a 30–60 minute job for someone comfortable removing shelves and interior panels. The most important part is making sure the water tubes are fully inserted into the quick-connect fittings before restoring water pressure.

To help any readers access this part, here is the process.

Before You Start

  1. Unplug the refrigerator.

  2. Shut off the water supply to the refrigerator.

  3. Dispense water for a few seconds to relieve pressure in the system.

  4. Place a towel under the work area to catch any residual water.

Accessing the Tank

The water tank is located inside the fresh-food compartment behind an access panel at the bottom of the left door.

  1. Remove any shelves that are in your way.

  2. Locate the interior cover panel.

  3. Remove the screws securing the panel and carefully pull it forward.

Disconnect the Old Tank

Once the cover is removed, you’ll see the water tank and its tubing.

  1. Take a photo of the tubing arrangement before disconnecting anything.

  2. Press the collar on each quick-connect fitting while gently pulling the water line out.

  3. Expect a small amount of water to drain from the lines.

  4. Remove any screws or retaining clips holding the tank in place.

  5. Lift the old tank assembly out.

Install the New Tank

  1. Position the new AJL72911507 tank exactly as the old one was mounted.

  2. Reinstall any mounting screws or clips.

  3. Push each water tube firmly into its fitting until fully seated.

  4. Give each tube a gentle tug to verify it is locked in place.

Reassemble and Test

  1. Reinstall the cover panel.

  2. Reinstall shelves if they were removed.

  3. Turn the water supply back on.

  4. Plug the refrigerator back in.

  5. Dispense several glasses of water to purge air from the new tank.

  6. Check carefully for leaks around every connection.

Thanks. Based on your reply, it sounds like this is something I can do myself.

I wanted to clarify that the water tank - which is located in the left door underneath the water dispenser, not in the fresh-food compartment behind the crisper drawers - is not the part that is leaking. The leak is in one of the push-to-connect fittings, as shown in the attached image, and the hope is that by replacing the whole assembly (which incidentally includes a new water tank) will fix the problem. If you’re able to confirm that, I’d appreciate it. Thank you!

Based on the image and where the leak is occurring, replacing the assembly should correct the issue.
