This is a single OEM water filter used in refrigerators to remove impurities and particles from water that goes through the water and ice dispenser. It is used for reducing cysts, turbidity, lead, mercury, herbicides, and more. If your icemaker is not making ice, not dispensing ice, dispenses too little ice, or there is leakage and the fridge is making loud noises, replacing the water filter may be the solution. This filter is located in the front, top right of side-by-side refrigerators. You will know it is time for a new filter when the light on the freezer door dispenser lights up red, or after 6 months (200 gallons) of use. No tools are required for this easy repair. First, press the release button to pull out the old water filter and push and lock in the new water filter. Run water through the dispenser for about 3 minutes to prime the filter for use. Dispose of the water or use it to water plants. Press the indicator for 3-10 seconds to reset after this repair is complete. This carbon-based filter measures 6 x 3 x 7 Inches and is white plastic. Note: You may also need to order the water filter base to make the water filter fit properly. Please use your model number to locate the filter base.
