Deciphering the error codes of air conditioners General climate makes it possible, without calling the wizard from the service, to troubleshoot.
Air Conditioner Error Codes General climate, displayed on the remote control:
- E2 - no contact with the temperature sensor;
- E3 - there is no contact with the temperature sensor of the evaporator;
- E4 - there is no contact with the temperature sensor of the condenser;
- E5 - increased temperature of the drainage pump motor;
- E6 - the protection mode of the outdoor unit (open circuit, overheating protection) is on;
- E7 - no contact with EEPROM;
- E8 - the drain pan is filled to the top.
Error codes on displays
Some errors can be fixed by yourself. To eliminate others, you will have to contact a specialist:
- operation + timer + def / fan - too much voltage is applied to the compressor more than once every 15 minutes. Disconnect the air conditioner from the power outlet;
- water alarm LED (blinks) - there is too much water in the condensate tank for more than 3 minutes. You must manually start the drain pump;
- water alarm LED (steady light) - the tank is full for more than 3 minutes. The device is in emergency mode. In order to eliminate this error code, disconnect it from electricity;
- def / fan (pre / def) - there is no contact with the temperature sensor on the condenser. The device will start working as soon as the temperature sensor turns on;
- All lights blink - violation of the function of the outdoor unit (overheating or hypothermia, power failure);
- Timer - short circuit or no contact with the internal temperature sensor;
- Operation - there is no contact with the temperature sensor on the evaporator or a short circuit in it;
- operation + timer - violation of contact with EEPROM. This error cannot be fixed on its own, since it is necessary to install a new control board.
Error codes for split systems like S-HR
Even with one equipment manufacturer, the designations always differ, so you should carefully study the instructions and know the exact model of your air conditioner and its units (internal and external). Only after these steps, you can pick up the exact decryption of such codes on the air conditioner as pre / def. The table below is just for this case.
Be careful, these codes are valid for the following models: S12HR, S09HR, S18HR, S07HR.
| operation | timer | defrosting | What is the problem |
| blinks | does not burn | blinks | Too high voltage applied to compressor four times in a row |
| Does not burn | blinks | blinks | Fan lasts longer than a minute |
| blinks | blinks | blinks | Worth compressor |
| does not burn | does not burn | blinks | No contact with temperature sensor on indoor unit pipes |
| does not burn | blinks | does not burn | There is no contact with the temperature sensor of the indoor unit measuring the room temperature |
| on | blinks | does not burn | EEPROM violation |
General Climate Air Conditioner Error for S24HR Model
| operation | timer | defrosting | auto | What is the problem |
| blinks | blinks | blinks | blinks | Compressor overvoltage four times |
| Does not burn | blinks | Does not burn | Does not burn | The temperature sensor of the indoor unit does not function |
| blinks | Does not burn | Does not burn | Does not burn | The temperature sensor does not function on the pipes of the indoor unit |
| Does not burn | Does not burn | blinks | Does not burn | The outdoor unit temperature sensor does not function |
| Does not burn | Does not burn | blinks | blinks | Overvoltage on the external module or the thermistor function is broken |
| Does not burn | Does not burn | Does not burn | blinks | EEPROM violation |
Errors of air conditioning General climate most often occur due to untimely service or violation of the rules for using the air conditioner.
