Use the manufacturer-linked catalog with the full label

Midea US Support links Parts & Accessories to its selected Encompass provider. Choose Washer/Dryer or enter the full model. A description search finds candidates; confirm the actual returned model before using its parts list.

Keep the model, suffix, production date and private serial record with the enquiry. Record the required assembly and orderable identifier separately from its diagram location. An owner manual and an exploded parts drawing serve different purposes.

A parts listing does not diagnose a fault or authorize internal work. Stop for unsafe movement, leaks or electrical signs. Do not bypass locks, reach inside an operating washer or remove covers for an undocumented test. Obtain qualified service when diagnosis or access is unsafe.

Why the same model can show two drive versions

The checked MLV45N1BWW model record labels these entries with old/new and bulletin qualifications:

Belt

12638000001161: old ribbed-belt entry. 12638000003042: new V-belt entry.

Clutch

12938000001941: old entry. 12938000000354: new entry.

These are catalog identities for this example, not a diagnosis or a blanket replacement recommendation. Don’t choose “new” merely because it sounds preferable, and don’t treat an old/new row as permission to combine components.

Resolve the production boundary before selecting parts

Bulletin PB-LAD10002, Revision 1, November 24, 2021 covers MLV45N1BWW, MLV45N3BWW and MLV45N1BWWC. It describes a V-ribbed-to-V-belt drive change, with other components updated, and a November 13, 2021 production change.

Have the provider compare the complete model, production date and private serial with the bulletin’s model-specific table and current catalog. Don’t extend that scope to another model.

If the record or fitted arrangement cannot be reconciled, leave the order unresolved. This is not a conversion guide; no internal disassembly or adjustment sequence is supplied.

Choose the next step from the evidence you have

The symptom hasn’t been diagnosed: start with the observed washer problem. A named belt, clutch or controller is not automatically the cause.

The catalog has a clear match with no unresolved qualifier: confirm the current part identifier, required kit contents and applicable repair instructions with the provider. Verify current terms and availability separately.

Old/new entries, a changed number or missing model remain: send the exact label record and proposed assembly to the provider. Ask which bulletin, production boundary or documented replacement establishes the match before committing.

The drive-belt reference explains the broader component role. The Midea hub retains model documents and service routes. Neither a similar photograph nor the Midea name establishes individual compatibility.
