What to match before buying
- The linked manufacturer sources explicitly list these 2 model codes for EDR4RXD1.
- Several sales model codes changed from Filter 4 to Filter A in November 2023. The complete 12-character revision code is required for the affected models.
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 EDR4RXD1 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.
