Midea air conditioner is divided into several models, and the machine error codes of different models are slightly different. For example, X appears on T3-type hang-up of Health Cool Star, indicating that the fan speed is out of control; O stands for open circuit or short circuit of indoor temperature and evaporator temperature sensor; A double star appears, indicating that there is an error in reading EEPROM parameters when power is on.
Midea's total health Q 1 cabinet, P3 stands for high and low voltage protection, and T 1 stands for sensor failure; P4 represents the phenomenon that the indoor evaporator protects the compressor from high temperature or low temperature; E2 indicates T2 sensor failure; P5 indicates that the outdoor condenser protects the compressor from high temperature; E3 indicates T3 sensor failure; P7 means to turn off the compressor when the outdoor exhaust temperature is too high; E5 stands for network communication failure; P9 is an air conditioner defrosting device to protect or prevent cold air from turning off the fan.
Through these different error reporting systems, we can quickly identify the problems of the machine and then find professional after-sales personnel for maintenance.
