Senville AURA / LETO Error Codes
Senville units are built on a Midea platform, so many codes match other Midea-based brands, but use the manual for your exact model.
| Code | Meaning | What to check |
|---|---|---|
| EH 00 | Indoor EEPROM malfunction. | Replace the indoor main PCB. |
| EH 0A | Indoor EEPROM parameter error. | Reprogram or replace the indoor PCB. |
| EL 01 | Indoor/outdoor communication error. | Interconnect wiring and connectors; replace a PCB if needed. How to fix → |
| EH 02 | Zero-crossing signal detection error. | Indoor main board. |
| EH 03 | Indoor fan speed out of control. | Indoor fan motor and control board. |
| EH 0b | Display board and control board communication error. | Display cable; one or both boards. |
| EH 60 | Room temperature sensor (T1) error. | Measure the sensor; check connector. How to fix → |
| EH 61 | Pipe temperature sensor (T2) error. | Measure the sensor; check connector. How to fix → |
| FH CC | Refrigerant sensor error. | Replace the refrigerant sensor module. |
| EH C1 | Refrigerant leak detected. | Leak search; inspect the sensor. How to fix → |
| EH C2 | Refrigerant sensor out of range and leak detected. | Replace the sensor and inspect the refrigerant lines. How to fix → |
| EH C3 | Refrigerant sensor out of range. | Replace the refrigerant sensor. |
| EC C1 | Leak detected at another indoor unit (multi-zone). | Leak search at the other heads. How to fix → |
| EC 51 | Outdoor EEPROM parameter error. | Reprogram or replace the outdoor board. |
| EC 52 | Outdoor coil temperature sensor (T3) error. | Measure the sensor; check connector. How to fix → |
| EC 53 | Outdoor ambient temperature sensor (T4) error. | Measure the sensor; check connector. How to fix → |
| EC 54 | Compressor discharge sensor (TP) error. | Measure the sensor; check connector. How to fix → |
| EC 56 | Indoor coil outlet sensor (T2B) error (multi-zone). | Measure the sensor; check connector. How to fix → |
| EC 07 | Outdoor fan speed out of control. | Outdoor fan motor and drive circuit. How to fix → |
| EL 0C | Low refrigerant. | Find and repair the leak, then charge by weight. How to fix → |
| PC 00 | IPM module protection. | Outdoor airflow and the IPM/inverter board. How to fix → |
| PC 01 | Voltage protection. | Supply voltage under load. How to fix → |
| PC 02 | Compressor or IPM over-temperature. | Outdoor airflow, refrigerant charge and flow. How to fix → |
| PC 03 | Pressure protection (low or high). | Pressure sensors/switches and refrigerant charge. How to fix → |
| PC 04 | Inverter compressor drive error. | Compressor wiring; test or replace the drive module. How to fix → |
| PC 0L | Low ambient temperature protection. | Normal in very cold weather; no action unless it persists. |
How to read the codes
- EH codes are indoor, EC outdoor, EL communication or refrigerant, PC protection (compressor and inverter), and FH/EH C codes are the refrigerant leak sensor on R-454B models.
- dF, CL, F, FP, FC, AP and CP are normal status messages (defrost, clean, etc.), not errors.
- On multi-zone systems, an indoor unit that won't run with no code may be a mode conflict: set all heads to the same mode.
Codes point to a circuit, not a part. Test before replacing boards or sensors. Inverter boards hold a dangerous charge after power-off; wait and verify DC bus voltage is gone before touching them. Refrigerant work requires EPA 608 certification.
