The Ultimate Kenmore Bottom-Freezer Refrigerator Water Filter Guide: Replacement, Troubleshooting, and Maintenance

Kenmore recommends swapping the water filter after six months of use or once it has filtered roughly 200 gallons of water—whichever milestone arrives first. The two‑year rule of thumb some owners cite is misleading; water flow rates and household usage vary dramatically. For a family that drinks eight glasses a day, the filter can hit the 200‑gallon mark in just four months. The refrigerator’s built‑in indicator light helps, but it’s calibrated to the average consumption, so logging your usage in a kitchen notebook or a phone reminder ensures you never miss the window.

A practical tip: mark the installation date on the filter housing with a permanent marker. When you glance at the fridge later, the date is right there, eliminating guesswork. If you notice a drop in water pressure or a faint chlorine taste before the six‑month mark, that’s a signal the filter is exhausted and needs an early replacement.

Genuine Kenmore filters carry the part number 10173679 (or 10173679‑A for newer revisions). The safest sources are Sears.com, Kenmore.com, and the official Whirlpool parts portal, which all guarantee compatibility. Local appliance repair shops often stock the part, and many big‑box retailers like Home Depot and Lowe’s carry it in the plumbing aisle under the “Kenmore/Whirlpool” label.

When shopping online, beware of third‑party sellers who list “compatible” filters at a discount. While some generic cartridges meet NSF/ANSI standards, they may lack the exact flow‑rate design Kenmore engineered for the dispenser’s pump. To avoid voiding your warranty, cross‑check the UPC and read customer reviews that mention a perfect fit for a bottom‑freezer model. If you’re on a tight budget, a reputable brand like EveryDrop (Whirlpool’s own line) offers a certified equivalent that fits the same housing.

Most Kenmore bottom‑freezer refrigerators route water through a dedicated shut‑off valve located behind the appliance. If you can locate that valve—usually a small brass knob on the copper line—you should turn it clockwise until it stops. This prevents a sudden spray if the O‑ring is damaged during removal.

However, many newer Kenmore units use a quick‑connect fitting that seals itself once the filter is twisted back into place. In those cases, you can leave the main supply on, remove the old filter, and install the new one without any water spillage. The key is to check your user manual: if it mentions a “water shut‑off valve,” use it; if not, the quick‑connect design makes a full shut‑off unnecessary.

1. Gather tools: a towel, a small flat‑head screwdriver (if your model has a retaining clip), and the new filter.

2. If your fridge has a shut‑off valve, turn it off. Open the dispenser door and place the towel underneath the filter housing to catch any drips.

3. Press the release button or turn the filter counter‑clockwise (usually a quarter turn) to release it. Pull the old filter straight out.

4. Inspect the O‑ring on the new filter; it should be smooth and free of cracks. Lightly lubricate it with food‑grade silicone grease if it looks dry.

5. Align the new filter’s tabs with the housing grooves and push it in until you feel a firm click. For twist‑in models, rotate clockwise until it stops.

6. Turn the water supply back on (if you shut it off) and watch for a steady stream from the dispenser. A few seconds of sputtering is normal as air clears the line.

7. If water continues to leak from the housing seam, double‑check that the filter is fully seated and that the O‑ring sits evenly in its groove. Tighten any loose mounting screws on the housing itself.

Following these steps eliminates most leak scenarios. The most common cause of post‑replacement drips is a misaligned O‑ring, which can be corrected by removing the filter, repositioning the ring, and reinstalling.

When a leak appears, the first instinct is to panic, but a systematic check saves time. Start by wiping the area dry and looking for the source: is water escaping from the filter housing, the dispenser nozzle, or the water line behind the fridge? If it’s the housing, the filter likely isn’t seated correctly. Remove it, reseat the O‑ring, and reinstall.

If the leak originates from the water line connection, tighten the compression fitting with a wrench—just a quarter turn; overtightening can crack the tubing. In rare cases, the line itself may be damaged during filter removal; inspect for kinks or cracks and replace the line if needed. After fixing, run water for a minute to ensure the pressure normalizes and the leak is gone.

Generic filters often advertise “up to 200 gallons” and claim NSF/ANSI certification, which sounds reassuring. The reality is that OEM Kenmore filters are calibrated for the exact flow rate and pressure that the dispenser’s pump expects. Using a lower‑flow generic can cause the ice maker to take longer to fill molds, leading to smaller or misshapen ice cubes.

On the flip side, a high‑quality generic can save 30‑40% on cost and still meet safety standards. If you choose a generic, verify the certification label (NSF/ANSI 42 for taste and odor, 53 for health contaminants) and read user feedback specific to your Kenmore model. Keep in mind that using non‑OEM filters may void the manufacturer’s warranty on the water system, though the overall refrigerator warranty typically remains intact.

The water filter directly influences ice‑maker performance because it regulates both flow rate and water purity. A clogged filter reduces pressure, causing the ice maker’s fill valve to close prematurely. The result is undersized cubes or a “click‑click” sound as the motor struggles to compensate.

Conversely, a fresh filter restores optimal pressure, allowing the ice maker to fill the mold completely. If you notice a sudden drop in ice output after a filter change, double‑check that the new filter is fully seated and that the indicator light has been reset—some models won’t resume normal ice cycles until the system acknowledges the new filter.

A quick test: fill a glass from the dispenser and compare the flow to a pre‑change baseline. If the stream is noticeably slower, the filter may be the culprit.

Overall, regular filter changes keep ice crystal formation consistent, preventing cloudy or freezer‑burned cubes.

Each Kenmore model has a slightly different reset sequence, but the most common method involves the “Ice” and “Water” buttons. Press and hold both for three to five seconds; the light should flash and then turn off, confirming the reset. Some newer models use a digital display—navigate to the “Settings” menu, select “Water Filter,” and choose “Reset.”

If the light refuses to reset, verify that the new filter is properly installed; the system won’t acknowledge a filter that isn’t fully engaged. In rare cases, a blown fuse in the control board can prevent the indicator from responding, requiring a technician’s inspection.

After installing a fresh filter, run water through the dispenser for about two minutes (roughly 2‑3 gallons). This flushes out carbon dust, air bubbles, and any residual manufacturing lubricants. Skipping this step can leave a faint charcoal taste in the first few glasses and may cause the dispenser to sputter.

If your fridge has a “quick‑fill” dispenser, you can fill a large pitcher and discard the first batch. For models with a separate “water line” for the ice maker, let the ice maker run a full cycle after the flush; the first tray of ice will absorb any remaining particles, ensuring subsequent cubes are crystal clear.

Beyond the blinking light, pay attention to subtle cues: a gradual metallic or chlorine taste, slower water flow, or a faint cloudiness in the water. Ice that forms with a white film or appears smaller than usual also signals a clogged filter. Some owners notice a slight increase in the refrigerator’s energy consumption because the water pump works harder against a restricted flow. If any of these symptoms appear, replace the filter even if the scheduled interval hasn’t elapsed.

Kenmore filters contain activated carbon and a plastic housing that can be recycled in most municipal programs. Contact your local waste‑management authority to confirm if they accept “household hazardous waste” or “plastic cartridges.” Many retailers, including Lowe’s and Home Depot, offer a take‑back program: bring the used filter to the store’s recycling bin and they’ll handle the disposal.

If you’re environmentally conscious, consider a mail‑in recycling service like TerraCycle, which provides a prepaid envelope for used filters. This ensures the carbon is properly processed and the plastic is repurposed, reducing landfill impact.

Kenmore’s bottom‑freezer line spans several series—2200, 2500, 3000, and newer 4000 models—each with subtle differences in housing design. While many share the 10173679 part, some older models (pre‑2005) use a larger “A” version with a different thread pitch. Always check the model number on the interior wall of the freezer compartment; the user manual lists the exact filter part.

If you’re upgrading from an older Kenmore to a newer one, you may need to purchase a conversion kit that includes a new housing adapter. This ensures a leak‑free seal and proper flow rate. Conversely, if you’ve inherited a Kenmore from a friend, verify the filter size before ordering; a mismatched filter can damage the dispenser pump.

Most homeowners can replace a Kenmore water filter in under ten minutes with basic tools. However, call a professional if you encounter any of the following: a cracked water line, persistent leaks after multiple reseats, or a malfunctioning ice maker that continues to produce undersized cubes despite a new filter.

A certified appliance technician can also test water pressure with a gauge; if it falls below the manufacturer’s spec (usually 40‑60 psi), the issue may be beyond the filter—perhaps a failing water inlet valve or a clogged supply line. In those cases, professional diagnosis prevents further damage and ensures your refrigerator’s warranty remains valid.

While the filter’s lifespan is primarily dictated by water volume, you can extend its effectiveness with a few habits. Install a whole‑house sediment pre‑filter if your home’s water has high mineral content; this reduces the load on the refrigerator’s cartridge. Periodically clean the dispenser nozzle with a soft brush to prevent mineral buildup that can mimic a clogged filter.

Also, avoid using the dispenser for high‑volume tasks like filling large pots; the sudden surge can strain the pump and accelerate filter wear. By treating the water system gently, you’ll notice fewer taste changes and longer intervals between replacements.
