2025-12-03

If you own a Frigidaire refrigerator, understanding how to properly maintain its air filter is critical to keeping your appliance running efficiently, preserving food quality, and preventing costly repairs. A clean, functioning air filter not only removes odors and contaminants from your fridge but also supports the unit’s cooling system, reducing energy consumption and extending its lifespan. This guide will walk you through why the air filter matters, how to identify the right replacement, step-by-step installation, maintenance best practices, and common troubleshooting tips—all tailored to Frigidaire models. Whether you’re a new owner or have had your fridge for years, this information will help you avoid common pitfalls and ensure your refrigerator performs at its best.

Why Your Frigidaire Refrigerator’s Air Filter Matters More Than You Think

Frigidaire refrigerators, like most modern appliances, are designed with advanced features to keep food fresh longer. One of their unsung heroes is the air filter. Here’s why it deserves your attention:

1. It Eliminates Odors and Contaminants

The air inside your fridge circulates constantly, carrying smells from spilled milk, strong cheeses, or leftover garlic. Over time, these odors can linger and transfer to other foods, ruining their taste. A Frigidaire air filter—typically a activated carbon or charcoal-based cartridge—traps these odor molecules, keeping your fridge smelling fresh. Some models also filter out mold spores, dust, and pet dander, which can grow on coils or contaminate food if left unchecked.

2. It Protects the Cooling System

Your fridge’s evaporator coils, located near the back or bottom, are responsible for cooling the air. Dust, lint, and other debris can accumulate on these coils, forcing the compressor to work harder to maintain temperature. A clogged air filter fails to trap this debris, allowing it to circulate and coat the coils. This not only reduces cooling efficiency (leading to higher energy bills) but can also cause the compressor to overheat, shortening its lifespan.

3. It Ensures Consistent Food Preservation

When the air filter is dirty, airflow in the fridge becomes restricted. This can create uneven temperatures, causing some areas to be too warm (risking spoilage) and others too cold (freezing delicate items like produce or dairy). A clean filter maintains steady airflow, ensuring every shelf stays at the optimal temperature—usually 35-38°F (1.7-3.3°C)—for food safety.

How to Identify the Right Frigidaire Air Filter for Your Model

Frigidaire produces dozens of refrigerator models, and not all air filters are interchangeable. Using the wrong filter can lead to poor fit, reduced filtration, or even damage to your appliance. Here’s how to find the correct one:

Step 1: Locate Your Refrigerator’s Model Number

The model number is typically printed on a sticker inside the fridge (often on the ceiling, side wall, or near the door hinge) or on the back panel. It will start with letters like “FF,” “FG,” or “FR” followed by numbers (e.g., FFTR1814QW). Write this down—you’ll need it to find the right filter.

Step 2: Check Your Owner’s Manual

The manual that came with your fridge lists compatible filter part numbers. If you’ve misplaced it, Frigidaire’s official website has a “Support” section where you can search by model number to download a digital copy.

Step 3: Understand Filter Types

Frigidaire uses two main types of air filters:

  • Standard Carbon Filters: These are the most common. They use activated carbon to absorb odors and are labeled with part numbers like ADQ36006101 or ADQ73600610.

  • HEPA/Allergen Reduction Filters: Some higher-end models (like those with advanced air purification systems) include HEPA filters that capture 99.97% of particles as small as 0.3 microns, including pollen, mold, and bacteria. These are often labeled with “HEPA” in the part number (e.g., ADQ73600611).

Step 4: Buy from Trusted Sellers

Always purchase filters from Frigidaire’s official store, authorized retailers (like Home Depot or Lowe’s), or reputable third-party sellers on Amazon that guarantee compatibility. Avoid generic filters that don’t list your exact model number—they may not fit or filter effectively.

How to Install a Frigidaire Air Filter: A Step-by-Step Guide

Installing a new air filter is a simple task, but doing it correctly ensures optimal performance. Follow these steps:

1. Turn Off Power (Optional but Recommended)

While most Frigidaire filters can be replaced with the fridge running, turning off the power (via the wall outlet or fridge’s control panel) adds an extra layer of safety, especially if you’re working in a tight space.

2. Locate the Filter Housing

Frigidaire places the air filter in one of three common areas:

  • Top-Mounted: Inside the fridge, near the top shelf (common in French door models). Look for a rectangular cover labeled “Air Filter.”

  • Bottom-Mounted: In the crisper drawer or behind a kick plate at the base of the fridge (common in side-by-side models). You may need to pull out the crisper drawer to access it.

  • Back-Mounted: On the back of the fridge, near the condenser coils (less common in newer models but found in older top-freezer designs). This requires pulling the fridge away from the wall.

3. Remove the Old Filter

Most filters are held in place by a spring-loaded clip or twist-lock mechanism. For top/bottom-mounted filters:

  • Press the release button (often red or blue) on the front of the housing.

  • Gently pull the old filter straight out. It may be dirty—avoid touching the sticky carbon side to prevent spreading debris.

For back-mounted filters:

  • Unscrew the cover panel to access the filter.

  • Slide the old filter out of its slot.

4. Prepare the New Filter

Remove any packaging from the new filter. Most Frigidaire filters have a small tab or notch that aligns with the housing—make sure to match this to ensure a secure fit.

5. Insert the New Filter

Push the new filter into the housing until you hear a “click” indicating it’s locked in place. If it’s a twist-lock model, rotate it clockwise until it’s snug.

6. Test the Seal

Close the filter housing cover. Run your hand over the edges—if there are gaps, the filter isn’t seated properly. Reinsert it and try again.

7. Reset the Filter Indicator Light (If Equipped)

Many Frigidaire models have a “Change Filter” light on the control panel. To reset it:

  • Press and hold the “Filter Reset” button for 3-5 seconds.

  • The light should turn off, indicating the new filter is registered.

Maintaining Your Frigidaire Air Filter: How Often to Replace and When to Clean

Even with regular use, air filters don’t last forever. Here’s how to care for yours:

Replacement Frequency

Frigidaire recommends replacing the air filter every 3-6 months, depending on usage and environment:

  • High-Use Households: If you open the fridge multiple times a day, store pungent foods (like fish or onions), or have pets, replace it every 3 months.

  • Low-Use or Clean Kitchens: If you rarely cook at home and keep the fridge organized, 6 months may suffice.

  • Signs It’s Time to Replace: Persistent bad odors, visible dirt on the filter, or the “Change Filter” light turning on (if your model has one).

Can You Clean a Frigidaire Air Filter?

Most Frigidaire filters are disposable and not designed to be washed. The activated carbon layer, which traps odors, is delicate—water or scrubbing can destroy it. However, if you have a reusable filter (rare in Frigidaire models), follow the manufacturer’s instructions to rinse it with warm water and let it air-dry completely before reinstalling.

Pro Tip: Extend Filter Life with Pre-Filters

Some Frigidaire models (especially those with external condenser coils) benefit from pre-filters—thin mesh screens that catch large debris before it reaches the main filter. These can be washed monthly and reused, reducing how often you need to replace the primary filter.

Troubleshooting Common Frigidaire Air Filter Issues

Even with proper care, you may encounter problems. Here’s how to fix them:

Issue 1: The “Change Filter” Light Won’t Turn Off

Cause: The filter wasn’t seated correctly, or the fridge’s control board needs a reset.

Solution: Remove the filter, reinsert it until it clicks, and reset the indicator light using the control panel. If it still won’t turn off, unplug the fridge for 10 minutes, then plug it back in—this resets the internal sensor.

Issue 2: Persistent Odors Even After Filter Replacement

Cause: The filter isn’t the only source of smells. Mold in the drain pan, spoiled food in hidden crannies, or a dirty gasket (the rubber seal around the door) could be the culprit.

Solution:

  • Clean the drain pan (located under the fridge) with warm, soapy water.

  • Wipe down shelves, drawers, and door seals with a mixture of baking soda and water.

  • Place an open box of baking soda in the fridge (replace monthly) as a natural odor absorber.

Issue 3: Reduced Cooling Performance

Cause: A clogged filter is restricting airflow, causing the evaporator coils to ice up or the compressor to overwork.

Solution: Replace the filter immediately. If the problem persists, check the coils for ice buildup—defrost the fridge by turning it off for 24 hours, then restart. If ice returns quickly, contact a Frigidaire technician.

Where to Buy Frigidaire Air Filters: Original vs. Third-Party

When shopping for replacements, you’ll have two options: original Frigidaire filters or third-party alternatives.

Original Frigidaire Filters

  • Pros: Guaranteed to fit and meet Frigidaire’s filtration standards. Backed by a warranty.

  • Cons: Slightly more expensive than third-party options.

Third-Party Filters

  • Pros: Often cheaper. Some brands claim “better” filtration (e.g., additional charcoal layers).

  • Cons: Risk of poor fit, which can allow debris to bypass the filter. Lower-quality carbon may not absorb odors as effectively.

Recommendation: Stick with original Frigidaire filters unless you’ve verified a third-party option with positive reviews and a money-back guarantee. The peace of mind—and potential savings on repairs—is worth the extra cost.
