Evidence before links
How compatibility gets verified.
Every definitive fitment statement should trace to a reviewed relationship between one canonical appliance model, one canonical part, and at least one stored source.
1. Establish the model identity
We preserve the submitted model number and create a separate normalized comparison value. Formatting changes—such as spaces or ordinary hyphens—can help search, but they never merge two records automatically.
2. Establish the part identity
A canonical part record is based on its manufacturer identity and part number. Marketplace titles, photos, or seller claims do not define the part.
3. Attach evidence to the relationship
Sources are prioritized in this order:
- Manufacturer manuals and product pages.
- Manufacturer support documentation.
- Authorized parts distributors.
- Credible independent sources when primary evidence is unavailable.
Retail listings may identify a lead, but they are not treated as definitive compatibility evidence by themselves.
4. Publish conservatively
A model page needs a normalized identity, a known brand and category, at least one approved evidence-backed relationship, a review date, and no unresolved high-severity contradiction. Thin or unverified records stay out of the public index.
Confidence labels
- Manufacturer confirmed: a primary manufacturer source explicitly supports the relationship.
- Cross-confirmed: more than one credible source supports the relationship after review.
- Not yet verified: the relationship is a lead, not a public recommendation.
- Disputed: credible evidence conflicts and the record requires resolution.
Corrections and review dates
Review dates describe when the source relationship was checked. They do not imply hands-on product testing. If you find a conflict, send the exact model, part number, and source.
