⚡ Microcontroller Error Codes
Midea Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| E1 | Indoor-outdoor communication error | Inspect wiring terminals 1-2-S, test DC communication voltage fluctuation, check optocouplers. |
| E2 | Zero-crossing signal detection failure | Check indoor PCB power supply circuit, replace main indoor control board if IC damaged. |
| E3 | Indoor fan speed out of control (BLDC feedback lost) | Clean blower wheel, inspect Hall sensor wiring, replace fan motor. |
| E4 | Indoor room temperature sensor open/short | Measure resistance 10k ohm at 25°C, replace room thermistor probe. |
| E5 | Indoor evaporator coil temperature sensor fault | Check coil sensor socket on PCB, replace pipe thermistor. |
| EC | Refrigerant leakage detection algorithm activated | Pressurize system with 400 PSI dry nitrogen, seal flare leak, vacuum, and recharge virgin R32. |
| P4 | Inverter compressor drive error / IPM module overtemperature | Inspect IPM heatsink thermal paste, check outdoor fan motor speed. |
