LG Air Conditioner Error Code 62

Error code 62 on an LG air conditioner means the inverter heatsink in the outdoor unit has reached a temperature above 100°C, which is beyond the safe operating limit. The system shuts down automatically to protect the inverter power module from permanent damage. Common triggers include blocked airflow, low refrigerant, a disconnected EEV connector, or poor power wire connections at the outdoor unit.

No, you should not attempt to keep operating the unit when error code 62 is active. The system has shut down because the inverter heatsink exceeded 100°C, and continued operation could permanently damage the inverter power module, which is one of the most expensive components in the outdoor unit. Leave the system off until the underlying cause is identified and corrected.

Repair costs vary widely depending on the cause. If the fix is as simple as clearing an obstruction or re-seating an EEV connector, costs may be limited to a service call fee, typically in the range of $75 to $150. If a refrigerant recharge is needed, expect to add $150 to $400 depending on refrigerant type and quantity. Inverter power module replacement, if the component was damaged by overheating, can range from $300 to $800 or more including labor.

Some causes of error code 62 can be addressed without professional help, such as clearing debris or obstructions from around the outdoor unit and checking that nothing is covering it. However, diagnosing refrigerant pressure, inspecting the Electronic Expansion Valve, and testing electrical connections typically require specialized tools and training. If clearing obstructions does not resolve the error, it is best to contact a certified HVAC technician.

A power reset may temporarily clear the error and allow the unit to restart, but the code will return if the root cause has not been addressed. Simply resetting the unit without fixing the underlying issue, such as restricted airflow or low refrigerant, risks repeated overheating and potential damage to the inverter electronics. Always diagnose and resolve the cause before attempting a reset.
