Senville AURA / LETO Error Codes

Applies to: Senville AURA / LETO. Code shown on the indoor unit display.

Senville units are built on a Midea platform, so many codes match other Midea-based brands, but use the manual for your exact model.

CodeMeaningWhat to check
EH 00Indoor EEPROM malfunction.Replace the indoor main PCB.
EH 0AIndoor EEPROM parameter error.Reprogram or replace the indoor PCB.
EL 01Indoor/outdoor communication error.Interconnect wiring and connectors; replace a PCB if needed. How to fix →
EH 02Zero-crossing signal detection error.Indoor main board.
EH 03Indoor fan speed out of control.Indoor fan motor and control board.
EH 0bDisplay board and control board communication error.Display cable; one or both boards.
EH 60Room temperature sensor (T1) error.Measure the sensor; check connector. How to fix →
EH 61Pipe temperature sensor (T2) error.Measure the sensor; check connector. How to fix →
FH CCRefrigerant sensor error.Replace the refrigerant sensor module.
EH C1Refrigerant leak detected.Leak search; inspect the sensor. How to fix →
EH C2Refrigerant sensor out of range and leak detected.Replace the sensor and inspect the refrigerant lines. How to fix →
EH C3Refrigerant sensor out of range.Replace the refrigerant sensor.
EC C1Leak detected at another indoor unit (multi-zone).Leak search at the other heads. How to fix →
EC 51Outdoor EEPROM parameter error.Reprogram or replace the outdoor board.
EC 52Outdoor coil temperature sensor (T3) error.Measure the sensor; check connector. How to fix →
EC 53Outdoor ambient temperature sensor (T4) error.Measure the sensor; check connector. How to fix →
EC 54Compressor discharge sensor (TP) error.Measure the sensor; check connector. How to fix →
EC 56Indoor coil outlet sensor (T2B) error (multi-zone).Measure the sensor; check connector. How to fix →
EC 07Outdoor fan speed out of control.Outdoor fan motor and drive circuit. How to fix →
EL 0CLow refrigerant.Find and repair the leak, then charge by weight. How to fix →
PC 00IPM module protection.Outdoor airflow and the IPM/inverter board. How to fix →
PC 01Voltage protection.Supply voltage under load. How to fix →
PC 02Compressor or IPM over-temperature.Outdoor airflow, refrigerant charge and flow. How to fix →
PC 03Pressure protection (low or high).Pressure sensors/switches and refrigerant charge. How to fix →
PC 04Inverter compressor drive error.Compressor wiring; test or replace the drive module. How to fix →
PC 0LLow ambient temperature protection.Normal in very cold weather; no action unless it persists.

How to read the codes

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.
