CH32High temperature in Discharge pipe of the inverter compressor

Name in the manufacturer's documentation (service manual): High temperature in Discharge pipe of the inverter compressor[1]

In plain words (editorial)

The discharge pipe of the inverter compressor is too hot. The service manual names overload operation (outdoor fan obstructed, screened or blocked), refrigerant leakage (shortage), a poor discharge sensor or a displaced EEV connector.

When to call a service technician: Make sure nothing blocks or covers the outdoor unit; if the code repeats, contact an LG-authorised service technician or your installer.
