Looking Up W11088559? How W11284458 Enters the Search
W11088559 is an earlier ice-maker reference associated with W11284458 in appliance-parts catalogs. That is useful when the label on an existing assembly differs from the number a store currently sells. It is the beginning of a lookup, not a substitute for checking the refrigerator model.
Preserve the old number
Photograph the original label before removing the assembly. Copy the complete refrigerator model separately, including the final revision characters. Do not discard the old number because the search engine prefers a newer one; it helps support explain the replacement history.
Verify the service application
Find the ice-maker position in the diagram for the complete model. Record the current service number and any application notes. Then compare the supplied assembly's plug, mounting arrangement and water entry with the original.
Different sellers may display manufacturer numbers, their own inventory codes and catalog identifiers such as AP or PS references together. Those identifiers can aid searching, but they are not independent confirmations of fit. One correct model-specific lookup is stronger evidence than several copied cross-reference lists.
Ask a precise question
Provide the model, original W11088559 label and the diagram result. Ask whether the actual W11284458-reference assembly being supplied matches that application and whether any existing covers or brackets must be transferred under the service instructions.
If the answer depends only on the Whirlpool brand, request the missing model check before ordering. Disconnect power and shut off water before replacement. This process also applies when a package label differs from the invoice: establish the documented relationship before connecting the part.
Product reference

Compare the W11284458 listing and product photographs with the complete appliance model before ordering. A symptom or similar appearance alone does not establish compatibility.
