Aeronik air conditioner's error (fault) codes

Aeronik air conditioners are manufactured at Gree industrial facilities. The assortment includes a line of household, semi-industrial and industrial air conditioners.

Household air conditioners belong to the budget class, therefore, they do not have an advanced function of self-diagnosis and troubleshooting. In case of problems with the operation and maintenance of these systems, you need to call the service center masters for diagnostics and troubleshooting.

In air conditioners of a higher level, the diagnostic function is present, so you can use the following list of fault codes:

Error codes for semi-industrial air conditioners

• E1 High compressor discharge pressure
• E2 Freezing of the indoor unit heat exchanger
• E3 Low compressor discharge pressure
• E4 High temperature of the discharge pipe
• E5 Compressor current relay tripped
• F0 Indoor air temperature sensor malfunction
• Malfunction of the temperature sensor of the heat transfer of the indoor unit
• Malfunction of the ambient temperature sensor in the outdoor unit
• E6 Switching fault
• E8 Motor overload protection tripped int. block
• F1 Malfunction of the temperature sensor on the heat exchanger F2 of the outdoor unit
• F3
• F4 Malfunction of the room temperature sensor

Aeronik air conditioner error codes

E1 - the pressure in the compressor discharge has increased;

E2 - the heat exchanger of the indoor unit froze;

E3 - the pressure in the compressor discharge has decreased;

E4 - the temperature of the discharge pipeline has increased;

E5 - actuation of the compressor current relay;

F0 - there are malfunctions in the temperature sensor of the air inside

premises, in a heat exchanger in an indoor unit or ambient air in an outdoor unit;

F0 - There may also be a freon leak in the indoor unit.

E6 - faults occurred in the commutation;

E8 - the internal block motor is overloaded;

F1 - there are malfunctions in the temperature sensor in the heat exchanger;

F4 - there are malfunctions in the temperature sensor of the discharged in

room air.

H1- is not an error. the air conditioner has switched to auto defrosting mode.
