LG Heat Pump Error Code E160

E160 on an LG heat pump indicates a software setup error in a peripheral control device that uses an option configuration. The error means that one of the accessory or expansion control devices connected to the system has not been correctly programmed or is missing required software option settings. This is a configuration-level fault, not a mechanical failure. A technician will need to review and correct the peripheral device's software settings to resolve it.

The E160 error is a software configuration fault and does not indicate a refrigerant leak, electrical hazard, or fire risk. However, the heat pump may not operate correctly or at full capacity while this error is active. It is reasonable to leave the system off until the error is resolved, especially if the unit is not heating or cooling properly, to avoid stressing other components.

If the fix involves only reprogramming the peripheral device's software settings, labor costs are typically in the range of $75 to $200 depending on your region and the time required. If the peripheral control board itself is faulty and needs replacement, parts and labor combined could range from $200 to $600 or more. Getting a diagnostic visit from a qualified technician is the best way to determine the actual repair scope and cost for your specific system.

Resolving E160 typically requires access to the system's service configuration menus and knowledge of the correct option codes for your specific setup. Most homeowners will not have access to these menus or the documentation needed to enter the correct values. It is strongly recommended to have a qualified HVAC technician handle this repair to avoid making configuration errors that could affect system performance or cause additional faults.

A simple power reset is unlikely to permanently clear E160 because the underlying cause is a software configuration issue that persists in the peripheral device's memory. The error may temporarily disappear after a reset but will return once the system checks the option settings again. A proper resolution requires correcting the software configuration in the affected peripheral device.
