The LG LFXC24726S refrigerator is known for its spacious layout, modern features, and solid day-to-day performance. Even a reliable refrigerator, though, can develop issues over time. If a part stops working, you may be able to replace it yourself instead of scheduling service right away, especially if the repair involves a common component and you have basic tools on hand.

This guide walks through the most common parts that fail on the LG LFXC24726S, explains the symptoms that point to each one, and shows how to replace them step by step. It also helps you decide when a repair is practical and when replacing the refrigerator may make more sense.

Common Faulty Parts in the LG LFXC24726S Refrigerator and How to Replace Them

1. Water Filter

Symptoms: Reduced water flow, bad-tasting water, or the filter indicator light is on.

Why you might replace it: Over time, the water filter collects sediment and impurities, which can reduce water flow and affect taste. Replacing it every 6 months helps maintain clean water and proper dispenser performance.

Step-by-step instructions for replacing the water filter:

1. Locate the water filter: It is usually inside the refrigerator compartment in the top-right area or in the base grille.

2. Remove the old filter: Twist the filter counterclockwise or pull it out if it is a push-in style.

3. Insert the new filter: Place the new filter into the slot and twist it clockwise if needed until it is secure.

4. Reset the filter indicator: Press and hold the reset button for 3 to 5 seconds if your model includes a filter alert.

5. Test the new filter: Run water through the dispenser to confirm good flow and normal taste.

When to call a professional: If replacing the filter does not restore normal water flow or improve water quality, the water inlet valve or water line may be the real problem.

2. Ice Maker

Symptoms: The ice maker is not producing ice, makes misshapen cubes, or is not dispensing ice correctly.

Why you might replace it: A failed ice maker assembly can stop ice production altogether. If the water supply and valve are working, replacing the ice maker itself is often the next step.

Step-by-step instructions for replacing the ice maker:

1. Unplug the refrigerator: Disconnect power before starting any repair.

2. Locate the ice maker: It is usually mounted inside the freezer compartment.

3. Disconnect the water line: Use a wrench if needed and disconnect the water supply line carefully.

4. Remove the old ice maker: Unscrew or unclip the unit from its mounting position and disconnect the electrical connector.

5. Install the new ice maker: Position the replacement unit, secure it in place, reconnect the wiring, and reconnect the water line.

6. Test the new ice maker: Plug the refrigerator back in and allow several hours to confirm normal ice production.

When to call a professional: If the replacement ice maker still does not work, the fault may be in the valve, water line, or control system.

3. Water Inlet Valve

Symptoms: No water reaches the dispenser or ice maker, or there is a leak around the inlet valve.

Why you might replace it: The water inlet valve controls the flow of water into the refrigerator. If it fails, water may stop completely or leak from the valve body.

Step-by-step instructions for replacing the water inlet valve:

1. Unplug the refrigerator: Disconnect power before working on the appliance.

2. Locate the valve: It is usually at the lower rear of the refrigerator behind an access panel.

3. Disconnect the water supply line: Turn off the water supply and disconnect the line from the old valve.

4. Remove the old valve: Take out the mounting screws and note how the wires and lines are connected.

5. Install the new valve: Mount the replacement valve, reconnect the wiring, and reconnect the water line.

6. Test the new valve: Turn the water back on, restore power, and test both the dispenser and ice maker.

When to call a professional: If replacing the valve does not restore water flow, the issue may involve the water supply or internal plumbing.

4. Condenser Coils

Symptoms: The refrigerator is not cooling properly, runs too often, or seems inefficient.

Why you might replace it: In most cases, condenser coils do not need replacement, but they often need cleaning. Dust and pet hair buildup can block heat release and reduce cooling performance.

Step-by-step instructions for cleaning the condenser coils:

1. Unplug the refrigerator: Disconnect power before maintenance.

2. Locate the condenser coils: They are usually on the back or beneath the unit.

3. Clean the coils: Use a vacuum with a brush attachment or a coil brush to remove dust and debris carefully.

4. Plug the refrigerator back in: Monitor cooling performance after cleaning.

When to call a professional: If cleaning the coils does not improve cooling, the issue may involve the compressor or sealed system.

5. Door Seal

Symptoms: The refrigerator does not stay cold, condensation forms around the door, or the door does not close tightly.

Why you might replace it: A worn or damaged door seal allows warm air into the refrigerator, causing cooling loss and higher energy use.

Step-by-step instructions for replacing the door seal:

1. Unplug the refrigerator: Disconnect power before beginning the repair.

2. Remove the old seal: Pull the old gasket away from the door. Remove any retaining screws or clips if present.

3. Clean the area: Wipe down the mounting surface so the new seal fits correctly.

4. Install the new seal: Press the new gasket into place evenly around the door perimeter.

5. Test the door: Close the door and check for gaps or signs of poor sealing.

When to call a professional: If the door still does not seal after replacing the gasket, the hinges or door alignment may need adjustment.

When to Repair vs. Replace

The LG LFXC24726S is a durable refrigerator, but as it ages, some repairs become less cost-effective. If the refrigerator is under 5 years old and the issue is relatively simple, such as a filter, ice maker, or door seal, repairing it is usually the best choice. If it is more than 10 years old, breaks down frequently, or needs expensive major components, replacement may make more sense.

Signs it may be time to replace:

• The refrigerator is over 10 years old

• The cost of repairs is higher than the cost of replacement

• The appliance has frequent breakdowns or reduced efficiency

Basic Maintenance Tips for Your LG LFXC24726S Refrigerator

• Clean the condenser coils: Clean them at least twice a year to support proper cooling.

• Replace the water filter: Install a new filter every 6 months for clean water and ice.

• Check the door seal: Inspect the gasket regularly so cold air does not escape.

• Defrost the freezer when needed: Prevent excessive ice buildup so airflow stays consistent.
