When your LG air conditioner starts acting up, the first thing you should do is check if it’s displaying any error codes on its screen. These codes are a way for the device to communicate specifically what’s going wrong with its system. Understanding these codes can be the difference between a quick fix and waiting days for a specialized technician.
At codigodeerror.com, we understand how important it is for you to solve these issues quickly and efficiently. That’s why we’ve prepared a detailed table with the most common error codes for LG air conditioners, their description, cause, and most importantly, the recommended solution for each one.
Before diving into the table, it’s important to understand some concepts that might seem technical but are quite simple:
- PCB EEPROM: Refers to a non-volatile memory used on the air conditioner’s printed circuit board (PCB) to store configurations.
- Internal pipe sensor: It’s a component that measures the temperature of the refrigerant in the air conditioner’s internal pipes.
- Evaporator: Part of the air conditioner where the refrigerant absorbs heat from the environment, cooling the air.
With these concepts clear, it will be easier to understand the error code table we present below:
| Error | Description | Cause | Solution |
|---|---|---|---|
| 1|0 | Fan motor malfunction. | Disconnect the fan motor connector / Interior fan failure motor lock | |
| 6|0|1 | Inverter PCB EEPROM error | Check the EEPROM checksum error by resetting the power | |
| CH34 | Safety relay | Detects abnormal pressure due to lack of sealing. Protects the unit from overheating | |
| E1/CH02 | Automatic short protection | Short or open in internal pipe sensor. | Call technical service |
| E2/CH01 | Automatic short protection | Short or open in internal pipe sensor. | Call technical service |
| E3/CH03 | Detects lack of refrigerant in the unit | Disconnect the device call sat | |
| E4 | Not a fault, the system is in defrosting. | • The system detects ice on the evaporator. Once defrosted, it restarts its operation. | |
| E5 | Water container full | • Check the cap and drain all the water you can, then re-cover the container. | |
| P2/FL | Depending on the model indicates full drain tray | To reset the unit unplug it from the network for 10 seconds then turn the power back on |
Our advice
Before attempting any repairs on your own, make sure to disconnect the air conditioner from the electrical supply to avoid accidents. If the problem persists after following the recommended solutions, it’s better to contact a specialized technician. Remember, prevention and regular maintenance are key to the proper functioning of your LG air conditioner.
