COMPLETE ERROR CODES LG AIR CONDITIONER

Here is a complete list of LG Multi Split Units Air Conditioner Error Codes and Inverter Fault Codes. When an error code appears on the LG Air Conditioner remote control or on the LG Air Conditioner LED panel wall unit. This error code pops up basically telling the user that something is wrong with the LG Air Conditioner unit. The error code displayed will inform you of a problem with the Air Conditioner

The following is a list of error codes on LG air conditioners:

Error Code CH05 - CH10 (Blinking Light)

Solution & Cause:

• Turn off the current in your AC unit and then turn it back on.
• If there are no loose connections, your air conditioner will start operating normally.
• Check the cable connections for loose connections on the unit.
• Charging less refrigerant (Freon) can trigger this error.
