How to Replace Your LG Refrigerator Air Filter

Understanding Your LG Refrigerator Air Filter System

LG refrigerators use air filters as part of their cooling and air circulation systems. These filters serve an important function by removing odors, bacteria, and other particles from the air inside your refrigerator. Over time, the filter accumulates dust, food particles, and other debris, which reduces its effectiveness. Most LG models require filter replacement every six months, though some newer models may go longer depending on usage patterns.

The air filter system in LG refrigerators typically includes one or more filters located in different areas of the unit. Some models have a filter in the back wall of the refrigerator compartment, while others may have filters in the ice maker area or near the ventilation system. Understanding where your specific filter is located is the first step toward successful replacement.

Your LG refrigerator likely came with documentation that shows the filter location. If you no longer have the original manual, you can find this information by checking the model number on your refrigerator. The model number is usually located on a label inside the fridge, often on the side wall or back wall. Once you have your model number, you can search for the specific filter location online through LG's website or user manual database.

Different LG models use different filter types. Some common ones include the ADQ73214402 filter (used in many French door models), the ADQ73214404, and various others specific to side-by-side or bottom freezer configurations. Knowing your exact filter type before you start will prevent purchasing the wrong replacement and wasting money.

Practical takeaway: Locate your refrigerator's model number and write it down. Search for your model's manual online to identify your air filter type and exact location. Keep this information in a convenient place for future reference.

Gathering the Right Tools and Replacement Filter

Before beginning the replacement process, you'll need to obtain the correct replacement air filter for your specific LG model. Purchasing the wrong filter is a common mistake that can result in wasted time and money. You have several options for obtaining the correct filter: you can buy directly from LG's parts website, purchase through major retailers like Amazon or Best Buy, or order from appliance parts specialists.

When selecting a replacement filter, you have choices regarding price and filter quality. OEM (original equipment manufacturer) filters made by LG are typically more expensive but are designed specifically for your model. Third-party filters that meet LG specifications are often less expensive and can work well, though quality varies between brands. Many people find that third-party filters that are LG-certified provide good performance at a lower cost than official LG filters.

Verify the part number before purchasing. Most LG air filters have part numbers beginning with "ADQ" followed by numbers. Double-check that the part number on the filter box matches what the manual specifies for your model. It's worth spending an extra few minutes on this step to avoid ordering errors.

In terms of tools needed, the good news is that most LG refrigerator air filter replacements require minimal equipment. You may need: a small flathead screwdriver or coin to loosen cover screws, a flashlight to see into the compartment, and possibly a clean cloth or paper towel. Some models have push-release filters that require no tools at all. Check your manual to see what, if anything, you'll need.

Practical takeaway: Before purchasing, confirm your exact model number and filter type. Compare prices from multiple retailers but prioritize getting the correct part. Gather any necessary tools and set them in one location. Plan to do the replacement when you have 10-15 minutes of uninterrupted time.

Preparing Your Refrigerator for Filter Replacement

Proper preparation makes the replacement process safer and more effective. First, turn off your refrigerator at the wall outlet or switch off the breaker that controls it. This is an important safety step, particularly if your model has an electronic control panel or if you'll be working near any electrical components. Some people worry that turning off the fridge will cause food to spoil, but a brief replacement lasting 10-15 minutes will not significantly affect food temperature.

Next, locate the air filter compartment. Depending on your model, this could be in several places: behind the crisper drawers in the refrigerator section, in the back wall of the main compartment, near the ice maker (usually in the upper back), or in a side compartment. Consult your manual for the exact location. You may need to remove drawers or shelving to access the filter. Many LG models have the filter in an accessible location specifically to make replacement straightforward.

If your filter is behind drawers, remove them carefully and set them aside in a clean area. Some drawers simply lift out, while others may have clips or guides you need to understand first. Take a moment to examine how they come out before pulling forcefully. Once removed, use a flashlight to look inside the compartment and familiarize yourself with the filter housing.

Take a photograph of the current filter and its position before removal. This reference photo can be helpful if you forget how it was positioned or if the installation instructions are unclear. The photo also serves as proof of the old filter if you're troubleshooting any issues later. Additionally, clear the area around your work space of any items that might be damaged by spilled water or small parts.

Practical takeaway: Turn off the refrigerator at the power source. Take a photo of the current filter in place. Carefully remove any obstacles blocking filter access. Have your replacement filter, tools, and paper towels ready and positioned within arm's reach of the work area.

Removing the Old Air Filter Safely

The method for removing your old filter depends on how it's mounted in your specific model. Most LG refrigerators use one of two common mounting systems: screw-in filters or push-fit filters that release with a simple mechanism. Your manual will indicate which type your model uses. If you're working without a manual, examine the filter carefully before attempting removal. Screw-in filters have threads visible on the housing, while push-fit filters have visible release tabs or clips.

For screw-in filters, use your flathead screwdriver or coin to turn the filter housing counterclockwise. The filter typically rotates about a quarter turn before it releases. Turn slowly and steadily—there's no need to force it. You may feel slight resistance, but if you encounter significant resistance, stop and reexamine the filter to ensure you're turning in the correct direction. Once it's loose, carefully pull the filter straight out toward you.

For push-fit or clip-release filters, look for visible tabs or buttons on the filter housing. These are usually colored differently from the surrounding plastic (often red or blue). Press or push these tabs as you pull the filter straight out. Some models have a single release point; others have multiple tabs that all need to be released. The filter should come out smoothly without requiring force.

As the old filter comes out, some water or moisture may drip out. This is normal—air filters in refrigerators accumulate condensation. Have paper towels or a small cloth ready to catch any drips and prevent water from getting on your floors or nearby items. Once the filter is removed, examine the compartment opening. You may notice dust or debris around the filter housing opening. Using a dry cloth, gently wipe out the opening to remove loose debris. This step isn't required, but it helps ensure your new filter functions optimally from the start.

Practical takeaway: Identify whether your filter is screw-in or push-fit type. Use steady, gentle pressure when removing it. Have paper towels ready to catch any moisture. Once removed, wipe out the compartment opening with a dry cloth.

Installing Your New LG Air Filter Correctly

Before inserting the new filter, remove it from its packaging and inspect it for any damage. Occasionally, filters arrive with bent tabs or crushed corners. If you notice any damage, this is the time to return it before installation. Most retailers accept returns on unopened or visibly damaged filters. Once you've confirmed the filter is undamaged, locate any protective seals or caps on the filter and remove them. Some new filters have plastic tabs or protective wrapping that must be removed before installation.

For push-fit filters, simply align the filter with the compartment opening and push it straight in until you hear or feel a click. This clicking sensation indicates that the filter has seated properly and the retention clips have engaged. Don't force it—if
