How to Change Air Filter in LG Fridge: Your Ultimate Step-by-Step Guide​

2026-01-13

Changing the air filter in your LG fridge is a simple, essential maintenance task that ensures your refrigerator runs efficiently, keeps food fresh, and maintains good air quality. To do it, you need to locate the filter compartment, typically inside the fridge, remove the old filter by twisting or pulling it out, insert a new compatible LG filter, and reset the filter indicator light if your model has one. This process usually takes under 10 minutes and requires no special tools. Below, I’ll break down every detail to make it foolproof, covering why it matters, how to handle different LG models, and tips to avoid common mistakes.

Why Changing Your LG Fridge Air Filter Is Crucial
Your LG refrigerator’s air filter cleans the air that circulates inside the fridge compartment. It removes odors, bacteria, and ethylene gas produced by fruits and vegetables. Over time, the filter becomes clogged with particles, reducing its effectiveness. A dirty filter can lead to unpleasant smells, faster food spoilage, and increased energy use as the fridge works harder to maintain temperature. LG recommends changing the filter every six months for optimal performance. In households with heavy usage or strong food odors, you might need to change it more frequently. Ignoring this can also strain the refrigerator’s cooling system, potentially leading to costly repairs. The filter is a small part, but it plays a big role in food safety and appliance longevity. Many LG fridges have a filter indicator light that alerts you when it’s time for a change. Pay attention to that light or set a calendar reminder. Fresh filters ensure your fridge maintains consistent humidity and temperature, which helps preserve nutrients in produce. They also prevent cross-contamination of flavors, so your ice cubes won’t taste like last night’s dinner. Investing in genuine LG filters or certified replacements guarantees compatibility and performance. Aftermarket filters might not fit perfectly or could lack the same filtration quality. Check your fridge’s manual for specific recommendations. In summary, regular changes save money on energy bills, reduce food waste, and keep your kitchen smelling clean.

Identifying Your LG Refrigerator Model and Filter Type
Before you start, identify your LG fridge model and the correct filter type. This step is critical because LG produces various refrigerator styles with different filter locations and parts. Find the model number, usually on a sticker inside the fridge compartment, on the door frame, or on the side wall. Common LG series include French Door, Side-by-Side, and Bottom Freezer models. Write down the model number, which looks something like “LFXS28968S” or “LRFVC2406S.” You can use this number to search for compatible filters online or in stores. LG uses several filter types, such as the LT1000P, LT800P, or LT700P. Some older models might have different codes. Refer to your user manual for the exact part number. If you’ve lost the manual, visit LG’s official website and use their parts lookup tool. Enter your model number to see recommended filters. You can also call LG customer support for assistance. When buying a filter, ensure it’s designed for your specific model. Using the wrong filter can cause air leaks, poor filtration, or damage to the fridge. Genuine LG filters are widely available at appliance stores, home improvement centers, and online retailers. Compare prices, but prioritize authenticity. Counterfeit filters may not meet safety standards. Once you have the new filter, unbox it and check for any included instructions. Keep the old filter until installation is complete, in case you need to match sizes. Knowing your model also helps with troubleshooting, as some LG fridges have unique filter compartments or reset procedures. I’ll cover those variations later. For now, have your model number and new filter ready before proceeding.

Tools and Preparation Needed for the Task
You need minimal tools for this job, making it a quick DIY project. Gather the new LG air filter, and that’s often all. No screwdrivers, wrenches, or special equipment are typically required. However, keep a flashlight handy if your fridge interior is dimly lit. Some people prefer wearing gloves to keep hands clean, but it’s optional. Ensure the fridge is plugged in and running normally; you don’t need to unplug it for safety, as the filter compartment is low-voltage and accessible. However, avoid touching any electrical components inside. Clear space around the fridge by removing items from the top or front if needed, but usually, you can work with the doors open. Take out any food items blocking the filter area, which is often on the back wall of the fridge compartment or on the ceiling. Place perishables in a cooler temporarily to keep them cold. Read the instructions on the new filter packaging for any specific steps. Check the old filter’s orientation before removing it—you can take a photo with your phone for reference. This helps during installation. Have a trash bag ready to discard the old filter immediately. It may contain trapped contaminants, so handle it carefully. Wash your hands before and after the task. Ensure the new filter is at room temperature; don’t install it straight from a cold garage. If your fridge has a water filter too, note that air and water filters are different parts. Don’t confuse them. The air filter is usually smaller and labeled for air purification. Finally, set aside 10-15 minutes of uninterrupted time. Rushing can lead to errors like improper installation. With everything prepared, you’re ready to start the change process.

Step-by-Step Guide to Changing the Air Filter
Follow these steps carefully for a smooth filter change. I’ll describe the most common scenario for LG fridges, then address variations. First, open the refrigerator doors and locate the air filter compartment. In most LG models, it’s on the back wall, near the top, behind a vent cover. Some models have it on the ceiling or in the base grille. Look for a rectangular panel labeled “Air Filter” or with a filter icon. If unsure, consult your manual. Once located, remove the cover. It might snap off by pressing tabs on the sides, or it could require a gentle pull. Don’t force it; if it feels stuck, check for hidden latches. With the cover off, you’ll see the old filter. It’s usually cylindrical or cartridge-shaped. To remove it, twist it counterclockwise about a quarter-turn, then pull it straight out. Some filters slide out without twisting. Note how it’s positioned—the arrows on the filter should point in the direction of airflow, typically toward the fridge interior. Discard the old filter. Before inserting the new one, inspect the compartment for dust or debris. Wipe it with a dry cloth if needed. Don’t use water or cleaners, as moisture can damage electrical parts. Now, take the new filter. Remove any protective packaging or seals. Align it with the slot, matching the arrows on the filter to the direction indicated in the compartment. Insert it firmly, pushing until it seats fully. If it twists, turn it clockwise until it locks. You should hear a click or feel it snap into place. Replace the cover by aligning it and pressing until it clicks shut. Ensure it’s secure to prevent air leaks. Next, reset the filter indicator light if your model has one. This is often a button on the control panel labeled “Filter Reset” or “Reset.” Press and hold it for 3-5 seconds until the light turns off or changes color. Refer to your manual for exact steps, as some LG fridges require navigating a settings menu. Finally, close the fridge doors. The fridge will resume normal operation. Check that the indicator light is off. Run the fridge for a few hours, and you should notice fresher air inside. This process is similar across many LG fridges, but I’ll cover exceptions in a later section.

Resetting the Filter Indicator Light on LG Fridges
Many LG refrigerators have a filter indicator light that alerts you when to change the filter. After installation, resetting it is crucial to ensure accurate future reminders. The method varies by model. For fridges with a basic button, look on the control panel for one labeled “Filter Reset” or an icon resembling a water droplet or filter. Press and hold that button for about 3 seconds until the light turns off. On some models, you might need to press it multiple times. For LG fridges with digital displays, you may need to navigate the settings. Press the “Settings” or “Menu” button, use arrows to select “Filter Reset” or “Air Filter,” and confirm with “Enter.” The light should reset. In newer smart models, you might do this via the LG ThinQ app on your smartphone. Open the app, select your fridge, and find the filter reset option. If the light doesn’t reset, ensure the filter is installed correctly. Sometimes, an unseated filter prevents resetting. Also, check that the fridge door is closed fully during the process. If problems persist, unplug the fridge for a minute, then plug it back in and try again. This can reboot the system. Consult your user manual for model-specific instructions. Some LG fridges don’t have a reset button; instead, the light turns off automatically after a new filter is installed and the fridge runs for a while. In that case, just wait 24 hours. Resetting the light is important because it tracks filter usage time. If ignored, the light stays on, causing nuisance alerts. Regular resets help maintain the fridge’s self-monitoring features. Write the date of change on the new filter with a marker for easy tracking. This practice complements the indicator light. If you lose your manual, search online for “LG [model number] filter reset” for videos or guides. LG’s website also has resources. Proper resetting ensures your fridge runs efficiently and you get timely reminders for the next change.

Common Problems and Troubleshooting Tips
Even with simple steps, issues can arise. Here’s how to troubleshoot common problems. If the filter won’t come out, don’t force it. Check if it’s twisted the wrong way. Try twisting clockwise or counterclockwise while pulling gently. Some filters have a release button; press it first. If stuck due to debris, use a flashlight to inspect. For stubborn cases, unplug the fridge briefly, but this is rarely needed. If the new filter doesn’t fit, verify it’s the correct part number. Compare it to the old filter size and shape. Remove any obstructions in the compartment. Ensure you’re not trying to install a water filter in the air filter slot. If it’s slightly off, realign it carefully. Don’t modify the filter or compartment. If the indicator light won’t reset, as mentioned, ensure proper seating. Also, check if the filter is genuine LG; some aftermarket filters might not trigger the reset. Try holding the reset button longer, up to 10 seconds. If the light stays on, the sensor might be faulty. Contact LG support. For unusual noises after installation, the filter might be loose, causing airflow vibrations. Re-seat it firmly. Also, ensure the cover is snapped on tightly. If odors persist, the filter might be defective, or there could be other issues like spoiled food. Clean the fridge interior and check for leaks. Run the fridge for a day to let the filter activate. Some filters use carbon, which needs time to work. If the fridge isn’t cooling well, the filter could be blocking airflow if installed backwards. Check arrow directions. Also, ensure the compartment isn’t blocked by food items. In rare cases, a faulty filter can affect cooling; replace it with another one. For models with multiple filters, like dual air filters, change all simultaneously. If you’re unsure, call a professional technician. Always prioritize safety: don’t disassemble other parts, and keep children away during the process. Most issues are resolved with patience and double-checking steps.

Maintenance Schedule and When to Change the Filter
LG recommends changing the air filter every six months under normal use. However, adjust based on your usage. In busy households with frequent door openings or strong-smelling foods, change it every 3-4 months. If you notice persistent odors or faster food spoilage, it’s time for a change. The filter indicator light is a good guide, but don’t rely solely on it, as lights can malfunction. Mark the date on your calendar or set a phone reminder. Some filters have a color-changing strip that shows when they’re expired; check it monthly. Also, consider environmental factors. If you live in a dusty area or have pets, filters may clog faster. After parties or holidays with extra fridge use, inspect the filter early. Keep a spare filter on hand so you’re never caught off guard. They have a long shelf life if stored in a cool, dry place. When changing, note the fridge’s performance. Regular maintenance includes cleaning the fridge coils and checking door seals, but the air filter is a separate task. Align filter changes with seasonal chores, like in spring and fall, for easy recall. If you have an LG smart fridge, it might send alerts via app; enable notifications. For vacation homes or infrequently used fridges, still change the filter annually, as it can degrade over time. Never wash and reuse the filter; it’s designed for one-time use. Replacing it timely ensures energy efficiency, potentially saving up to 10% on electricity bills. Also, it extends the life of your fridge by reducing strain on fans and motors. Make it a habit: when you change smoke detector batteries, change the fridge air filter too. This proactive approach prevents bigger problems and keeps your food fresh.

Specific Instructions for Different LG Refrigerator Models
While the general process is similar, some LG models have unique features. For French Door LG fridges, the air filter is often on the back wall of the fresh food compartment. Remove shelves if needed for access. In Side-by-Side models, it might be on the ceiling or behind a kick plate. Check your manual. For LG fridges with Craft Ice or special features, the filter could be in the ice maker area; consult diagrams. In older LG models, the filter might be behind a grille at the bottom front. To access, gently pull the grille off, then slide out the filter. Some high-end LG fridges have two air filters: one for the fridge and one for the freezer. Change both at the same time. They’re usually located similarly. For LG InstaView or Door-in-Door models, the process is the same, but be careful with glass panels. In LG LinearCooling refrigerators, the filter is typically on the back wall; ensure you don’t damage any sensors nearby. If your model has a water and air filter combo, they’re separate; change the water filter separately every 6 months too. For compact LG fridges, filters might be smaller; use exact replacements. When in doubt, search online for a video tutorial for your specific model number. Many appliance repair sites have visual guides. LG’s official YouTube channel also offers demonstrations. Always follow model-specific instructions to avoid voiding warranties. If you rent or own a commercial LG fridge, filters may need more frequent changes. Contact LG support for clarification. Adapting to your model ensures a smooth process and optimal performance.
