Choose between three distinct references

279640 is the pulley-wheel reference. WP691366 is another idler assembly, and W10837240 is an idler pulley with bracket. They remain separate part numbers. For example, 3CE2110XMW0 is documented for WP691366 and GEW9200LL1 for W10837240. Those examples identify specific applications; they do not prove that either assembly replaces the 279640 wheel.

A retailer may list a reference for appliances carrying other brand names. That is a catalog relationship to investigate model by model, not a reason to treat a brand family as interchangeable. Keep the actual brand and full model from your label when reviewing the model list and contacting a retailer.

A wheel and a repair kit solve different ordering questions

Some listings supply a pulley separately; others bundle multiple belt-system components. Read the quantity and contents, then compare them with the diagram and the actual repair assessment. A kit number should not be substituted into a wheel lookup simply because its photograph includes a pulley. Each component may require separate fit evidence.

Before ordering, record any readable number on the old part. A different number might be an older service reference, a production mark or an unrelated component identifier. Search it and inspect the relationship label. If the catalog has no supported connection, ask the retailer to identify it using the complete model and diagram.

Inspect safely before choosing a part

Noise or a drum that does not turn can justify investigation, but neither symptom proves the idler is responsible. The belt and drum supports can require separate assessment. Disconnect power before inspection, follow the manufacturer instructions and use a qualified technician for uncertain internal access. Do not use this category page as a belt-routing diagram or move gas connections during a part check.

Understand the evidence label

The 279640 record combines catalog information with a compatible-product seller model list. Some W10837240 rows also use a seller model guide. Other rows are backed by catalog compatibility tables or model-specific part lists. The source type and literal model are recorded individually, so corroboration should not be read as a physical installation test. Read the confidence for your exact model, confirm whether hardware is included and check installed-part returns. Single-source rows remain single-source even when other models qualify the same reference for publication.

Before you choose

Does appearing in this category confirm my model?

No. Check the complete model on the individual part page. A shared family, brand or part type does not establish fit.

What if my model is missing?

Our catalog is a reviewed subset. Keep the full suffix and ask the retailer to confirm the exact diagram item. An unlisted model is unknown, not a confirmed mismatch.
