What is the Kenmore 46-9911 Filter?
The Kenmore 46-9911 (also cataloged as part number 04609911000 or 9911) is an internal water filtration cartridge designed for specific Kenmore side-by-side and French door refrigerators. Utilizing a dense activated carbon block core, it is tested to reduce chlorine taste, odor, rust, particulate Class I, and volatile organic compounds (VOCs) to deliver crisp water and transparent ice.
The cylindrical cartridge features a top push-button or slide-in locking head designed specifically for Kenmore interior filter compartments, maintaining a tight hydraulic seal against line pressure surges.
What is the Frigidaire WF2CB Filter?
The Frigidaire WF2CB (commercially branded as the PureSource2 filtration system and cross-referenced as part number 240394501) is manufactured by Electrolux for Frigidaire and Electrolux side-by-side and multi-door refrigerator platforms. Certified under NSF/ANSI Standards 42 and 53, it actively traps lead, mercury, microbial cysts (Cryptosporidium and Giardia), turbidity, and agricultural pesticides.
The WF2CB cartridge features a front-facing release button with dual front O-ring ports that connect directly into the upper right ceiling manifold of Frigidaire cabinets.
Are Kenmore 46-9911 and Frigidaire WF2CB the Same Filter?
No, they are not the exact same filter. While both models share a cylindrical form factor and serve similar filtration roles, they are engineered to distinct manufacturer specifications. Kenmore 46-9911 is built for Sears/Kenmore platforms, whereas the WF2CB is built for Electrolux/Frigidaire platforms. However, because Electrolux historically manufactured select refrigerator lines for Kenmore (models beginning with prefix 253.), certain Kenmore units utilize Frigidaire filtration assemblies.
Cross-Reference & Specification Comparison Table
| Feature Specification | Kenmore 46-9911 | Frigidaire WF2CB (PureSource2) |
|---|---|---|
| Primary OEM Manufacturer | Kenmore / Sears PartsDirect | Electrolux / Frigidaire Genuine Parts |
| Rated Service Life | 6 months or 300 gallons (1,135 L) | 6 months or 300–400 gallons |
| Filtration Certifications | NSF/ANSI 42 (Aesthetics) | NSF/ANSI 42, 53 (Health Contaminants) |
| Key Interchangeable Numbers | 04609911000, 9911P, 46-9911 | 240394501, 240396401, FC-100, NGFC-2000 |
Compatibility and Connection Port Differences
Understanding port geometry is critical to prevent leaks and manifold failure:
Housing and locking alignment tabs
The Frigidaire WF2CB features an integrated push-button release mechanism that mounts horizontally in the ceiling recess. In contrast, standard Kenmore 46-9911 units utilize a twist-and-lock or drop-down collar. Forcing an incompatible cartridge into the wrong manifold risks fracturing internal water line connectors.
Brand compatibility: Kenmore, Frigidaire, and Electrolux
| Filter Model | Directly Compatible Brand / Series | Incompatible Appliance Platforms |
|---|---|---|
| Kenmore 46-9911 | Select Kenmore side-by-side & French door platforms | Frigidaire PureSource3, GE MWF, Whirlpool Filter 1 |
| Frigidaire WF2CB | Frigidaire, Electrolux & Kenmore (Model prefix 253.) | Frigidaire ULTRAWF, EPTWFU01, Whirlpool Filter 2 |
How to Identify and Choose the Right Filter
4-Step Identification Guide
- Locate the Data Plate: Find the manufacturer tag on the inner cabinet wall or behind the lower crisper bin to confirm whether your appliance is built on a Kenmore (e.g., 253.xxxxxx) or Frigidaire platform.
- Examine the Installed Cartridge: Check the printed label on the existing filter for "WF2CB", "PureSource2", or "46-9911".
- Inspect the Port Head: Verify whether your housing uses a front-facing push-button ejector (WF2CB) or a top-twist locking neck.
- Verify via Cross-Reference Tools: Search your full appliance model number on Smartfiltersusa to confirm certified fitment prior to purchase.
Installation and Replacement Guide
Step-by-Step Installation Process
Step 1: Locate the Compartment — The filter housing is typically positioned in the upper right interior ceiling of the fresh food compartment.
Step 2: Release the Old Cartridge — Firmly press the push-button release on the housing until the filter pops outward, or turn counterclockwise 1/4 turn depending on your unit type.
Step 3: Unpack the Replacement — Remove all protective plastic wrap and terminal caps. Inspect dual O-rings for clean seating and lubricate lightly with water if dry.
Step 4: Insert and Lock — Slide the new cartridge straight into the manifold housing until you hear a solid click, ensuring the ejection button resets flush.
Step 5: Purge & Flush the System — Dispense 2 to 3 gallons (approx. 3 to 4 minutes) through the door dispenser to clear trapped air pockets and loose carbon fines.
Step 6: Reset Filter Light — Hold down the Filter Reset touchpad on your refrigerator interface for 3 seconds until the indicator cycles to green.
Maintenance and Care Tips
Filter Lifespan & Quality Best Practices
| Maintenance Check | Recommended Frequency | Operational Target |
|---|---|---|
| Cartridge Replacement | Every 6 months / 300 gallons | Prevents carbon saturation and maintains flow rate |
| Flow Rate Verification | Monthly check | Detects sediment buildup in supply line early |
| O-Ring & Manifold Check | At every replacement | Ensures watertight connection without leaks |
| Spare Filter Storage | Cool, dry area (unopened) | Preserves activated carbon absorption capacity |
Frequently Asked Questions About 46-9911 & WF2CB Filters
1. Can I use a Frigidaire WF2CB filter in a Kenmore refrigerator that specifies 46-9911?
Only if your Kenmore refrigerator was manufactured by Electrolux (model number starting with 253.) and uses the PureSource2 slide-in housing. If your model specifies standard 46-9911 twist connections, they are physically not interchangeable.
2. What happens if an incompatible filter is forced into the housing?
Forcing a non-matching cartridge can crack the plastic receiver manifold, tear the O-ring seals, or cause high-pressure water leaks behind internal storage drawers.
3. Are there universal filters that fit both Kenmore and Frigidaire fridges?
No. Refrigerator manufacturers employ proprietary connection geometries and internal bypass valves that require exact matching part specifications.
4. How do I know if my refrigerator takes 46-9911, 46-9915, or WF2CB?
Check the printed part number on your existing cartridge or consult the data sticker inside your refrigerator cabinet to match the exact factory manual code.
5. Can I clean and reuse my carbon water filter cartridge?
No. The microscopic pores within the activated carbon block permanently trap chemical contaminants and cannot be backwashed or regenerated.
6. What contaminants do these replacement filters reduce?
Certified replacement filters reduce 99% of lead, cysts, chlorine taste, offensive odors, rust particles, and VOCs according to NSF/ANSI Standards 42 and 53.
7. What should I do if the new filter causes a knocking noise or low water flow?
A knocking noise indicates trapped air pockets in the internal line. Running 2 to 3 gallons continuously through the water dispenser expels air and normalizes line pressure.
8. Where can I buy genuine and certified Kenmore and Frigidaire replacement filters?
You can purchase genuine, factory-tested replacement filters directly through Smartfiltersusa with guaranteed compatibility and fast delivery.
Conclusion
Selecting the correct replacement cartridge between the Kenmore 46-9911 and Frigidaire WF2CB (PureSource2) is essential for protecting your appliance from leaks while securing crisp, clean drinking water and ice for your household. Verifying your refrigerator’s complete model number and adhering to the recommended 6-month replacement schedule guarantees peak filtration performance and protects internal ice maker solenoids.
