Where your Frigidaire water filter sits and why it needs replacing
Your Frigidaire refrigerator's water filter lives in one of two places: either inside the fridge (usually in the upper right corner or along the top edge of the interior wall), or underneath the fridge behind a kick plate at the bottom front. The filter catches sediment, chlorine, and other particles from your water line so your ice maker and water dispenser work properly. Over time—typically every six months to a year depending on your water quality—the filter clogs and stops working well.
When the filter is due, your fridge will either show a red light on the water dispenser, display a message on the control panel, or straightforward stop dispensing water clearly. Replacing it is straightforward and takes about five minutes. You do not need tools or a plumber.
Key Takeaways
- Frigidaire filters are located either inside the fridge (upper corner or top edge) or underneath behind the kick plate, depending on your model.
- You need the correct replacement filter model number, which is printed on your current filter or found in your refrigerator's manual.
- The filter twists out counterclockwise by hand, and the new one twists in clockwise until it stops—no wrench or plumber needed.
- After installing a new filter, run water through the dispenser for 30 seconds to flush air and reset any warning lights.
- Keep your old filter's model number so you can order the same replacement next time.
Finding your filter and identifying the correct replacement
Before you start, locate your filter. Open your refrigerator and look in the upper right corner or along the top interior wall—many Frigidaire models mount the filter there. If you do not see it inside, close the fridge and look at the bottom front. Kneel down and remove the kick plate (the panel that covers the space between the fridge and the floor). The filter may be mounted horizontally behind this panel.
Once you find it, write down the model number printed on the filter itself. It usually starts with "WFCB" or "WFCS" followed by numbers. If you cannot read it clearly, check your refrigerator's manual—the model number is listed there too. You can also find it on a sticker inside the fridge, usually on the side wall or back. Order the exact same model number as a replacement. Using the wrong filter can damage your water line or dispenser.
Removing the old filter
Have a small bowl or towel ready—a little water may drip when you remove the filter. If the filter is inside the fridge, reach up and locate the filter cartridge. You will see a plastic housing with the filter inside. Grip the filter firmly and turn it counterclockwise (to the left) by hand. It will loosen and come free. Some models have a release button or lever near the filter—press or pull it while turning if the filter does not budge.
If the filter is under the fridge behind the kick plate, the process is the same: turn counterclockwise by hand until it comes free. Set the old filter aside. Wipe away any water or debris from the filter housing with a clean cloth.
Installing the new filter
Remove your new filter from its packaging. Before inserting it, check that any protective caps or seals on the filter are removed—some filters come with plastic end caps that must come off first. If your new filter has a rubber gasket or O-ring around the base, make sure it is seated properly and not twisted.
Insert the new filter into the housing and turn it clockwise (to the right) by hand until it stops. Do not force it—it should tighten smoothly and stop on its own when seated correctly. You should feel a slight resistance as the gasket compresses, but you should not need to strain. If it does not turn smoothly, remove it, check that the gasket is straight, and try again.
Flushing the system and resetting warning lights
After the new filter is installed, run water through the dispenser for about 30 seconds. This flushes air out of the line and removes any loose carbon particles from the new filter. The water may look slightly cloudy or taste a bit off for the first few gallons—this is normal and will clear within a day or two of normal use.
If your fridge has a water filter warning light or message on the control panel, it should turn off automatically after you run water through the dispenser. If it does not, check your manual for a reset button—most Frigidaire models have a small button near the water dispenser or on the control panel that you hold for three to five seconds to clear the alert. After resetting, the light should go dark.
When to call a professional
If water leaks from the filter housing after you install the new filter, turn off the water supply to the fridge when ready (the shutoff valve is usually behind the fridge where the water line enters). Remove the filter, check that the gasket is clean and not damaged, and reinstall it. If it still leaks, the housing itself may be cracked—contact a Frigidaire service technician or a local appliance repair company.
If your fridge stops dispensing water even after you install a new filter and flush the line, the problem may be a frozen water line, a broken valve, or a kink in the tubing behind the fridge. These issues require professional diagnosis and repair.
Keeping track of your filter schedule
Write the date you installed the new filter on a piece of tape and stick it to the filter housing. This makes it straightforward to remember when you last replaced it. Most Frigidaire filters last six to twelve months depending on your water quality—if your water is very hard or has a lot of sediment, you may need to replace it more often. If you notice the water pressure dropping or the water tastes off before six months have passed, the filter may be clogged early.
Keep the model number of your current filter in your phone or a note on your fridge so you can order the replacement quickly when it is time. Ordering ahead means you will have the new filter on hand before the old one fails completely.
Frequently Asked Questions
What happens if I do not replace the filter?
A clogged filter reduces water pressure at the dispenser and ice maker, and stops filtering out sediment and chlorine. Over time, particles can damage the water valve or clog the ice maker. Replacing the filter every six to twelve months keeps everything working properly.
Can I use a different brand of filter?
No. Always use the exact Frigidaire model number for your fridge. Third-party filters may not fit correctly, could leak, or may not filter properly. Using the wrong filter can void your warranty and damage the water line.
Why is water leaking from under my fridge after I replaced the filter?
The gasket on the new filter may not be seated correctly, or the old gasket may still be stuck in the housing. Remove the filter, clean the housing thoroughly, check that the new filter's gasket is clean and straight, and reinstall it. If it still leaks, the housing may be cracked and needs professional repair.
Do I need to turn off the water before replacing the filter?
No. The filter cartridge itself does not require the water supply to be shut off. A small amount of water may drip when you remove the old filter, but this is normal. Have a towel ready to catch it.
How do I know which model filter my Frigidaire needs?
The model number is printed on your current filter. If you cannot read it, check your refrigerator's manual or look for a sticker inside the fridge listing compatible filter models. You can also call Frigidaire customer service with your fridge's serial number and they will tell you the correct filter model.
