Why the Final Characters Matter in a W11284458 Model Check
A refrigerator family name is useful for browsing, but a complete model is needed to select an ice-maker assembly. W11284458 appears in specific Whirlpool model diagrams; that does not make every refrigerator beginning with the same few letters a match.
Copy the entire label
Use a clear photograph rather than memory or an abbreviated retailer description. Preserve zeros, letters and the revision characters at the end. If a character is ambiguous, enlarge the original image and compare it with the appliance documentation before searching.
Do not substitute a purchase receipt's shortened model name for the appliance label. A marketing family or finish description may omit the revision needed by the parts catalog.
Check the relevant diagram position
Open the complete-model diagram and locate the ice-maker assembly. Record the listed service number and any supersession information. Then compare the original assembly number, connector, mounting arrangement and water entry with the offered replacement.
If the catalog does not recognize the full model, ask the appliance manufacturer or a parts specialist to resolve it. Removing the final characters to force a search result may return a neighboring revision with a different application.
Keep a concise fit record
Save the model photograph, diagram reference, original label and supplier's answer. This record is useful if the received assembly differs from the order or a later service number appears.
A successful model check is an explanation of why this assembly belongs in this appliance. A search result containing both strings, or a button that announces compatibility without consulting a real database, does not provide that evidence.
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.
