Every useful answer starts with a source.

One identity, several kinds of evidence.

An efficiency certification can establish a reported energy measurement. An installation guide establishes required clearances. A parts catalog establishes fitment only within its stated model and revision scope. These are separate claims.

What we keep with a fact

The exact source model, market, original value, units, measurement context, record or document locator, observation time, and source identity. Source observations stay separate from editorial selections. Equally ranked conflicting observations are displayed as needing resolution.

What we do with unknowns

An empty field is unknown, not zero or false. We do not generate retail model numbers from certification wildcards. We do not infer common firmware, button sequences, or part compatibility from similar model codes.

Documents and images

Manuals open at their official source or its linked document host. We do not publicly host PDFs or create a download proxy. Model photos must be explicitly paired with the full model code by their source, or tied to a documented finish or regional SKU variant. Regional SKU references show the full photographed retail code and explain inferred relationships in the credits. Manufacturer and retailer thumbnails retain their copyright and source attribution; no license or permission is asserted. Creative Commons photos retain their recorded licenses. General category photos are kept in category navigation. A missing model photo is shown as unavailable, rather than replaced with another appliance’s photograph. See the photograph credits and license links. Original category drawings remain as fallback illustrations.

Topic coverage and generated guidance

The plan’s 50 topic families have a finite model-topic inventory. Category eligibility and recorded features determine each model’s URLs. GPT-6 Luna drafted 50 core modules, 68 category modules, and 23 symptom modules. Shared text is explicitly labeled; no production-year grouping or common repair platform is inferred. Schema validation, source references, and applicability checks are automated. They do not constitute technician review. No undocumented code meaning, button sequence, or part fitment is generated as an exact-model fact.

Generic guidance pages are available to owners but kept out of search indexing. Indexable pages require a stronger model evidence threshold. The topic directory exposes coverage and an example for every topic family.

Brand and product-family guidance

The brand/family library adds 71 researched profiles and 771 topic notes. Manufacturer-documented families match only explicit full model codes. Brand/configuration groups match recorded design descriptions; a bottom-freezer record does not establish French doors, and a shared prefix does not prove a shared control platform. Broader brand notes identify feature variations and the source’s applicability.

Model-specific prose interprets recorded capacity, electrical, cooling, spin, drying, display, connection and energy facts for the selected topic. Source links accompany those checks. Comparison groups use the recorded brand, design and source class, with factual ranges; they do not establish parts interchange or current stock. General category guidance appears below these more specific sections.

Publication and review

Catalog imports validate identity and field structure automatically. Manufacturer links are associated with their exact source pages. A catalog record is not a technician-approved repair procedure. Deep service guidance remains unpublished until source applicability and appropriate technical review are established.

ENERGY STAR data is credited to the US Environmental Protection Agency. Historical appliance facts are credited to the California Energy Commission. Certification status reflects the imported snapshot. Specs & Parts has no manufacturer or agency affiliation.

Corrections and privacy

Corrections are stored for review and never automatically change published facts. Do not submit serial numbers or other personal information. Comparison selections remain in your browser. Tool and document actions may be counted anonymously in the application database. The public website also records sanitized document requests and first-party browser page timing, with restricted access and rolling 60-day retention.
