Use the full model number for non-filter parts
Whirlpool lists EDR4RXD1 as the water filter for WRX735SDHZ. That verifies this filter need; it does not mean every internal or service part is shared across every production revision. For anything other than the verified water filter, copy the entire model number from the refrigerator data tag before ordering.
