How to Replace Air Filter on LG Refrigerator: A Step-by-Step Guide for Homeowners​

2025-12-05

Replacing the air filter on your LG refrigerator is a simple yet critical maintenance task that ensures your appliance runs efficiently, keeps your food fresh, and maintains optimal cooling performance. Over time, air filters trap dust, debris, and odors, becoming clogged and less effective. If you’ve noticed your fridge running louder, food spoiling faster, or the “change filter” light glowing, it’s time to swap out the old filter. This guide walks you through every step, from preparation to testing, so you can do it yourself without professional help. By following these instructions, you’ll save money on service calls and keep your LG fridge in top shape for years.

Why Replacing Your LG Refrigerator’s Air Filter Matters

Before diving into the “how,” let’s clarify the “why.” The air filter in your LG fridge serves two main purposes:

  1. Air Quality Control: It captures airborne particles like dust, pollen, and pet dander, preventing them from circulating into your fridge and contaminating your food.

  2. Efficiency and Performance: A clogged filter forces the fridge’s fan to work harder, increasing energy consumption and straining components. This can lead to higher utility bills and premature wear.

LG recommends replacing the filter every 6–12 months, depending on usage. Households with pets, frequent door openings, or in dusty environments may need to replace it more often. Ignoring this can result in reduced cooling power, unpleasant odors, and even ice buildup in some models.

Step 1: Gather Your Tools and Supplies

You don’t need specialized tools to replace an LG fridge air filter, but having a few items on hand will make the process smoother:

  • Replacement Filter: Ensure it’s the correct model for your LG fridge. Check your fridge’s manual or the current filter for a part number (e.g., LG LT1000P, LT1200P). You can buy genuine filters from LG’s website, appliance stores, or retailers like Amazon. Avoid generic filters—they may not fit or filter as effectively.

  • Towel or Paper Towels: To wipe up any condensation or spills.

  • Gloves (Optional): For added hygiene when handling the old filter.

  • Screwdriver (Rarely Needed): Some older models have screws securing the filter cover; check your manual first. Most modern LG fridges use snap-on covers.

Step 2: Locate the Air Filter in Your LG Refrigerator

The location of the air filter varies by LG model, but there are common spots to check:

Top-Mounted Filters (Most Common)​

Many LG French-door and side-by-side refrigerators have the filter in the upper right corner of the fridge compartment. Look for a small, round or rectangular cover labeled “Air Filter” or with a icon (like a circle with arrows). It may be hidden behind a flip-down panel or a small door.

Bottom-Mounted Filters (Less Common)​

Some models, especially bottom-freezer fridges, place the filter in the kick plate (the panel at the bottom front of the fridge). To access it, kneel down and look for a small, rectangular cover held in place by clips or screws. You may need to remove the kick plate entirely by sliding it out or unscrewing it.

Freezer Compartment Filters​

A few LG models (often older ones) have the filter inside the freezer. Check the upper back wall of the freezer for a similar “Air Filter” cover.

Pro Tip: If you can’t find the filter, consult your LG fridge’s user manual. It includes a diagram of your specific model’s components. You can also search LG’s support website using your fridge’s model number (found on a sticker inside the fridge or on the back).

Step 3: Remove the Old Air Filter

Once you’ve located the filter, follow these steps to remove it:

  1. Turn Off Power (Optional but Recommended): While most LG fridges don’t require unplugging, turning off the ice maker or water dispenser (if connected) can prevent leaks. For added safety, unplug the fridge from the wall outlet.

  2. Open the Filter Cover:

    • If it’s a snap-on cover, gently press the tabs or edges and pull it toward you. Some covers swing open like a door—push the tab and lift.

    • If secured with screws, use a screwdriver to remove them, then set the cover aside.

  3. Pull Out the Old Filter:

    • Most filters have a tab or handle on the end. Grasp it firmly and pull straight out. It may resist slightly due to the seal—wiggle it gently if needed.

    • Note the orientation: The filter has an arrow indicating airflow direction (usually pointing toward the back of the fridge). Take a photo or mark this before removing it to ensure the new one is installed correctly.

Step 4: Prepare the New Filter for Installation

Before inserting the new filter, take a moment to inspect it:

  • Check for Damage: Ensure the new filter isn’t dented or torn. If it is, contact the seller for a replacement.

  • Remove Protective Packaging: Most new filters come with a plastic wrap or cap covering the intake end. Peel this off—leaving it on will block airflow.

Step 5: Install the New Air Filter

Now, insert the new filter:

  1. Align the Arrow: Match the airflow arrow on the new filter to the direction indicated in your fridge (usually toward the back). This ensures air flows through the filter correctly.

  2. Push Firmly: Slide the filter into the slot until it clicks into place. You should feel a secure fit—no wobbling.

  3. Close the Filter Cover: Snap the cover back into place or reattach screws. Ensure it’s flush with the fridge interior to prevent air leaks.

Step 6: Test the Filter and Reset the Indicator Light

After installation, verify everything works:

  1. Plug In the Fridge (If Unplugged): Restore power and wait 5–10 minutes for the system to reset.

  2. Check for Leaks: If your filter is near the water dispenser, run water for a few seconds to ensure no drips around the filter area.

  3. Reset the “Change Filter” Light: Most LG fridges have a filter reset button. Locate it (often near the filter cover or inside the fridge) and press it for 3–5 seconds. The light should turn off. If it doesn’t, consult your manual—some models require holding the button longer or using the control panel.

Troubleshooting Common Issues

Even with careful steps, you might encounter problems. Here’s how to fix them:

  • Filter Doesn’t Fit: Double-check the part number. LG filters are model-specific—using the wrong one won’t work.

  • “Change Filter” Light Stays On: You may have forgotten to reset it. Try pressing the reset button again. If it persists, the fridge might not detect the new filter—ensure it’s fully inserted and aligned.

  • Water Leaks After Replacement: If your filter is near the water line, you may have disturbed the connection. Tighten any loose fittings or replace the water filter (if applicable).

Maintaining Your LG Refrigerator’s Air Filter Long-Term

Replacing the filter is just the start. To keep your fridge running smoothly:

  • Mark Your Calendar: Note the replacement date on a sticky note or set a phone reminder.

  • Inspect Monthly: Even if you don’t replace it, check the filter for excessive dust. If it looks dirty before 6 months, replace it early.

  • Keep the Fridge Clean: Dust the exterior and wipe spills promptly to reduce the amount of debris reaching the filter.

Final Thoughts

Replacing your LG refrigerator’s air filter is a quick, low-cost task that pays off in fresher food, lower energy bills, and a longer-lasting appliance. By following these steps—locating the filter, removing the old one, installing the new filter correctly, and resetting the indicator—you’ll maintain peak performance with minimal effort. Remember, when in doubt, consult your LG fridge’s manual or contact LG support for model-specific guidance. With regular filter changes, your fridge will thank you by keeping your food cold, fresh, and safe.

Now that you know how to replace the air filter on your LG refrigerator, put this knowledge to use and enjoy the benefits of a well-maintained appliance!
