: Indoor Temperature Sensor Error . This usually indicates an open or closed circuit in the indoor air thermistor.
: Discharge Temperature Error . The discharge temperature has exceeded 130°C, likely due to a faulty discharge thermistor or low refrigerant.
: Indoor Fan Motor Error . The indoor fan is not rotating correctly. Lg Inverter Ac Error Codes
: DC Link Low Voltage . The DC voltage has dropped below 140V.
: Compressor Overheating . The discharge pipe temperature is too high. : Indoor Temperature Sensor Error
: Inverter/Compressor Error . Points to a problem with the compressor power supply or phase.
: Outdoor Fan Motor Error . The outdoor fan motor has failed or is blocked. The discharge temperature has exceeded 130°C, likely due
