LG Air Conditioner Error Code E162

E162 indicates an EEPROM error related to the MICOM control system. It means either there is a physical problem with the EEPROM chip or its solder connections, or communication between the EEPROM and the MICOM microcomputer has failed. The EEPROM holds model-specific configuration data that the unit needs to operate, so this fault prevents normal function.

A power reset alone may clear the code if the fault was caused by corrupted EEPROM data rather than a physical hardware problem. If the underlying solder joint or chip failure is not corrected, the E162 error will return after power is restored. Re-entering the model configuration options before the reset improves the chance of a successful recovery.

Repair costs vary depending on the root cause. If the fix involves only re-soldering EEPROM pins and re-entering model data, labor costs are typically modest, generally in the range of $75 to $150. If the main control board requires replacement, parts plus labor can range from $200 to $500 or more depending on the unit model and local service rates.

Basic steps such as performing a full power reset by shutting off the unit at the breaker for several minutes are safe for a homeowner to attempt. However, diagnosing and repairing solder joint failures, re-entering model options through the service menu, or replacing the control board requires technical knowledge and is best handled by a qualified technician.

No. When the E162 fault is active, the MICOM cannot access its stored configuration data, and the unit is not operating normally. Continuing to run the system in this condition is not recommended as it could lead to uncontrolled or incorrect operation. The unit should remain off until the fault is diagnosed and resolved.
