This hub is open, but it stays out of search results until it carries verified content, because an empty page helps nobody. In the meantime, the cross-brand symptom guides cover behaviour that applies to most heat pumps, and the error-code index may already document a code that matches yours.
Before you use a code table
- Record the full indoor and outdoor model numbers from the data plate, not just the brand name.
- Photograph the display while the code is showing. Some systems clear the code on power interruption and it can be difficult to reproduce.
- Note what the system was doing when the code appeared: starting, running, defrosting, or idle. That context narrows the cause faster than the code alone.
