Every answer has boundaries.
Our first version publishes a source-linked code index for one manual and only two narrow context pages. It does not turn a code into a repair instruction.
What counts as evidence
Each index label is pinned to a manufacturer document, its revision, market and printed page. Context pages require an additional exact excerpt. We link to the document so you can check it directly.
How model scope works
Manufacturer codes may differ by model family, series or control. Our pages state the exact documented scope. If we cannot establish that scope, no code page is generated.
What the automatic gate excludes
The current generator blocks fault diagnosis, installation instructions, component replacements and compatibility recommendations. A fault label may appear in the index, but it never becomes a repair explanation page. Missing or conflicting evidence also blocks publication. Source presence alone is not proof that a generated explanation is safe or correct, so our public wording stays close to the manufacturer's status label.
What this site cannot replace
It cannot inspect your equipment or determine why a system behaves a certain way. Never use a status reference as permission to open a service panel, bypass a safety device or work on gas, wiring or refrigerant. Follow the manufacturer's safety instructions and contact a qualified professional when service is needed.
