Sanyo error code & blinking light lookup

Which models and codes are covered?

Search model-scoped Sanyo SAP-KRV wall-mounted inverter split and XHS ceiling-recessed diagnostic rows. These manufacturer-authored service-manual copies are hosted by third-party manual libraries, so match the exact model family before diagnosis.

Choose SAP-KRV or XHS before following a meaning because shared codes can identify different faults. For SAP-KRV, match the exact ION, TIMER, and OPERATION lamp pattern to the manual reference. For XHS, search the code shown on the wired controller.
