Mitsubishi Electric equipment reports two-character codes such as P8 or U2 on the controller, and flashes an operation lamp pattern when no controller is fitted.

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 ductless mini-splits, 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.
