Haier Aircon 115 Error Code
Use this Haier 115 error code guide to confirm the source table meaning, capture the reporting equipment and model, and match the service manual before diagnosis. Match the model first; same-looking codes can point to different rows.
What does Haier 115 mean?
Haier 115 is listed as inverter DC-bus voltage too high and module DC-bus overvoltage in MRV-S MVHP outdoor unit and MRV5 AV08-AV26IMVEVA - outdoor failure table source rows. The loaded row is source-backed by official diagnostic material. Do not collapse this code across model families; use the model, series, or system type to choose the right row. Confirm the exact model, series, or signal row before accepting a parts quote.
Choose the matching source row
The same visible code has more than one source-backed meaning. Match the model family, system type, or reporting unit before approving parts.
| Code | What it means | What to check first |
|---|---|---|
| MRV-S MVHP outdoor unit | Inverter DC-bus voltage too high | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| 115-1 - compressor module 1 | Module DC-bus overvoltage (compressor module 1) | Use suffix -1 on the outdoor display to identify compressor module 1. |
| 115-2 - compressor module 2 | Module DC-bus overvoltage (compressor module 2) | Use suffix -2 on the outdoor display to identify compressor module 2. |
| 115-4 - fan module 1 | Module DC-bus overvoltage (fan module 1) | Use suffix -4 on the outdoor display to identify fan module 1. |
| 115-5 - fan module 2 | Module DC-bus overvoltage (fan module 2) | Use suffix -5 on the outdoor display to identify fan module 2. |

What to do now
Use these steps to record evidence and match the installed model to its service manual before diagnosis or a repair quote.
