Why does my LG ARUN Air Conditioner show a high pressure error at cooling?
If your LG Air Conditioner's outdoor fan shows a high-pressure error during cooling, it could be due to a motor failure or poor ventilation around the outdoor heat exchanger. First, turn off the outdoor units for a while and then check if the outdoor fan is working. Also, make sure there are no obstructions blocking airflow around the outdoor units.
What to do if the outdoor EEV in my LG ARUN has no operating sound at applying power?
If the outdoor EEV in your LG Air Conditioner isn't making any operating sounds when power is applied, the coil might have failed. Check the resistance between the terminals to diagnose this issue.
Why does the compressor stop during running in my LG ARUN Air Conditioner?
If your LG Air Conditioner's compressor stops while running, it might be due to motor insulation failure. Check the resistance between the terminals and the chassis.
What to do if my LG Air Conditioner's outdoor EEV heating fails and defrosts frequently?
If the outdoor EEV in your LG Air Conditioner is experiencing heating failure and causing frequent defrosting, it could be due to a bad connector contact. Inspect the connector to resolve this issue.
What to do if LG ARUN Air Conditioner's outdoor EEV heating fails and the outdoor heat exchanger part is frozen?
If your LG Air Conditioner's outdoor EEV is experiencing heating failure and the outdoor heat exchanger part is frozen, the EEV may be clogged. Service is necessary to resolve this issue.
What to do if my LG ARUN Air Conditioner's outdoor EEV has low pressure error or discharge temperature error?
If your LG Air Conditioner's outdoor EEV is showing a low-pressure error or discharge temperature error, it could be that the EEV is clogged. Service is necessary to resolve this issue.
How to troubleshoot a non-operating compressor in my LG Air Conditioner?
If the compressor in your LG Air Conditioner isn't operating, it could be due to broken motor insulation. Check the resistance between the terminals and the chassis.
