Where our information comes from
Manufacturer material is primary. Community discussions can suggest additional checks, but a single report is not proof.
We distinguish manufacturer explanations, editorial safety advice and user experiences. We do not claim success rates unless the source provides evidence. If a code is not confirmed for a specific model, the page says so.
Risky electrical, refrigerant, battery and data-destructive procedures are not presented as routine DIY fixes.
2026 source verification review
Not all codes are verified for every model. Each page indicates whether its code family was matched in manufacturer material, whether sources conflict, or whether an exact match remains pending. A code alone does not prove a part failure.
Primary sources are manufacturer support pages and model manuals. An accessible link does not establish applicability across all models.
How we label error-code evidence
Matched model manual: Code meaning is associated with a documented model/model family, not every product from that brand.
Manufacturer code/support list: A manufacturer source states the basic code meaning, but exact model compatibility may still need checking.
Code listing only: The code is listed but its technical meaning is unverified; these pages are temporarily excluded from search indexing.
Conflicting sources or models: Different official references may describe the same code differently. Differences are disclosed and no part failure is assumed without diagnosis.
Audit labels reflect recorded editorial checks; they do not mean every URL was revalidated today or every supported model was independently tested.
v29 model evidence and action-safety review
Exact models are marked confirmed only where the error code is printed in a manufacturer manual covering those model identifiers. Generic support lists are not proof of exact compatibility. Where sources differ, distinct meanings and manufacturer references are displayed.
Step badges identify observation, manual-guided user care, or professional support; they do not guarantee a repair is safe. Electrical internals, gas and refrigerant circuits remain for professionals.
Model matching and evidence status
A listed error code is not proof it has the same meaning on every model. At the time of this release, 32 records have an archived manufacturer-PDF mapping, 12 have a secondary comparison, and 1,139 records do not have an independently documented model-code mapping. The 801 historical model candidates and 338 originally empty model fields are not marketed as verified matches. Existing PDF references were not all re-opened during this review.
