Error Code In Haier AC

An error code in Haier AC is a number or message that shows up when something goes wrong with your AC. It helps you figure out what the problem is so you can fix it. 
There are two major Haier AC series we are going to discuss about them:

Haier AC E Series
Haier AC F Series

E Series Code PDF In Haier AC

An E series code is a way to show a specific problem or error with a system. It helps identify issues and figure out what needs fixing.
Here are the series of E series error code in Haier AC:

Series Description 
E7

The indoor and outdoor units are having trouble communicating with each other.

E1 

The indoor temperature sensor isn't working.

E2  The pipe temperature sensor isn't working. 
E4 The indoor EEPROM has malfunctioned. 
E5  The indoor unit's anti-frost protection is activated. 
E9  The indoor unit is overloaded when in heating mode. 
E14 The indoor fan motor is not working properly.
 

F Series Code PDF In Haier AC

An F series error code in a Haier AC shows a specific problem, like sensor issues, communication errors, or motor faults. These codes help pinpoint the problem so it can be fixed quickly.
These are the series F error code in Haier Ac:

Series Description 
F1  IPM protection safeguards the system's power module from potential damage or issues. 
F2  Instantaneous over-current protection of the compressor ensures the compressor is shielded from sudden electrical surges or spikes. 
F3  There's a communication error between the power module and the main PCB board. 
F4  The compressor's protection against high discharge temperatures. 
F6 

The outdoor ambient sensor is not functioning correctly.     

F7

The suction temperature sensor is not working properly.

F8 

The DC fan motor is not working correctly.
