DIY: How to Change a Refrigerator Water Filter


If you have a refrigerator with a built-in water dispenser and ice maker, you know this feature is super convenient. But no one likes dirty water. It's important to change the water filter in your fridge regularly so you enjoy the cleanest water possible. Luckily, this is a very simple task that can be completed in just a few minutes.

What You'll Need:

Refrigerator water and ice dispenser

Step 1. Remove the Old Cartridge

Locate the water filter cartridge cap in the front base grille below the freezer compartment door. Rotate the cap counterclockwise to a vertical position and pull the cap and filter cartridge out through the base grille. There will be water in the cartridge. Some spilling may occur.

Remove the cartridge cap by sliding it off the end of the old cartridge. The cap will slide to the left or right. Do not discard the cap.

Step 2. Install the New Cartridge

Take the new cartridge out of its packaging and remove protective cover from o-rings. Slide the cartridge cap onto the new cartridge. With cartridge cap in the vertical position, push the new filter cartridge into the base grille until it stops. Rotate the cartridge cap clockwise to a horizontal position.

Step 3. Run Water Through the Dispenser

Run water through the refrigerator water dispenser until it consistently runs clear. Tthis should occur after about 2-3 gallons or 6-7 minutes. Running the water will clean the system and remove air pockets from the lines. If air pockets are present, you'll notice short spurts of air coming through the water dispenser. Additional flushing may be required.

Step 4 Know When Your Filter Needs to Be Replaced Again

  • Models with base grille indicator lights -  There is a water filter status light located at the top of the refrigerator compartment that will help you know when to change your water filter cartridge in the future. The light will change from green to yellow when it is almost ready to be replaced (when approximately 90% of the filter life has been used). When the light turns yellow, be sure to have a new filter ready to install, however you do not necessarily have to replace the filter until the light turns red, or if water flow has noticeably decreased.

    After changing the water filter cartridge, reset the water filter status light by pressing and holding the RESET for 2-5 seconds. The status light will change from red back to green when the system is reset.
  • Models with non-indicator lights - If your refrigerator does not have the water filter status light, you should plan to change the water filter cartridge every 6 to 9 months depending upon your usage. If the water flow to the water dispenser or ice maker decreases noticeably before 6 months have passed, replace the water filter cartridge more often.

Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after going through the filtration system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
