Modern living room life is indispensable for the home to add one or two, or even more than 10 types of household appliances, frequency conversion air conditioning is one of them. Today we are going to bring you the relevant analysis of the fault code of Gree inverter air conditioning, and I hope you can solve the urgent need for you when you encounter a fault.

Gree frequency conversion air conditioning common fault code detail
E1: High pressure protection for the compressor
1. There are obstacles in front of the condenser
2, the outdoor ambient temperature is higher than 43 degrees to start cooling
3. Abnormal control loop
4, the high pressure pipe pressure is too high pressure switch action
E2: compressor low pressure protection
1. Insufficient refrigerant
2. The expansion valve is half blocked and the solenoid valve is faulty
3. The filter is half blocked
E3: evaporator anti-freezing protection
1. The indoor fan does not rotate or the tuyere is blocked
2. The indoor ambient temperature is below 18 degrees
3, the air conditioning temperature tube plug is broken
4. The air conditioning control loop is abnormal
5, the plug of the temperature sensor is not inserted
E4: compressor exhaust pipe overtemperature protection.
1, compressor aging.
2. The system is blocked.
3, the external heat dissipation is not good.
E5: overcurrent protection.
The above is about the Gree inverter air conditioning fault code analysis of the relevant introduction, although it seems that the code is very much, it seems to be dazzling, but you may wish to collect, if encountered, you can refer to the solution.
