What to match before buying
- The linked manufacturer sources explicitly list these 94 model codes for WF3CB.
- US refrigerator water-filter cartridge reference. Exact listed appliance codes only; no inferred finish or engineering suffix.
- Pack SKUs identify the same cartridge family in different pack quantities; they are not extra cartridge families.
- Manufacturer's package illustration on pages 1 and 5 explicitly prints WF3CB under HDWF3CB. Exact appliance code retained.
Find the model and filter codes
- Photograph the rating label inside the refrigerator.
- Keep the complete model code, including any finish, market or service revision suffix.
- Find that exact code in the model list on this page; an unlisted suffix needs its own manufacturer confirmation.
- Compare WF3CB with the cartridge specified in the appliance documentation.
- Compare the reference and pack on the final Amazon page; the shopping destination does not establish compatibility.
Other models and cartridge variants
- These sources do not extend compatibility to unlisted model variants or revisions.
- US source coverage does not establish compatibility for another regional model.
