According to some reports, about a third of the Russian air conditioning market is represented by the products of this company. Founded in the early 80s of the last century, products Haer quickly gained popularity due to the high quality of technology and the use of the latest technological developments. Now Haier is one of the hundred most famous equipment manufacturers in the world, one of the first among Chinese firms to officially enter the US market.
Common mistakes
Most often, the errors of the Haer air conditioners are caused by improper operation and illiterate attempts to repair the devices themselves.
Having studied the error codes for haier air conditioners, it will be much easier to figure out.
| Haier air conditioning error code | Breakage |
| E0 | Impaired condensate drain |
| E1 | Compressor increased pressure |
| E2 | Indoor unit heat exchanger covered with ice |
| E3 | Not enough compressor pressure |
| E4 Air Conditioner Error Haier | Compressor overheating |
| E5 | Compressor shut off due to increased load |
| E6 | No communication between blocks |
| E7 | The internal module does not respond to commands from the remote |
| E8 | Overload of the indoor motor |
| F0 | Room temperature sensor disconnected |
| F1 | The temperature sensor of the heat exchanger of the indoor module has turned off |
| F2 | The temperature sensor of the heat exchanger of the external module has turned off |
| F3 | The street temperature sensor has disconnected |
| F4 | The temperature sensor has turned off on the air supply |
| Ff | Disrupted power |
