Samsung Air Conditioner Error Code E163

E163 indicates a remote controller option error for the indoor unit, meaning the configuration settings that define how the remote controller interacts with the indoor unit are either missing or contain incorrect values. This is a commissioning or setup fault rather than a mechanical failure. The unit will not operate normally until the correct option codes for the specific model are entered through the service menu or remote controller.

A simple power reset will not clear E163 because the error is caused by a configuration problem, not a temporary fault. The missing or incorrect remote controller option settings will still be absent or wrong after a reset, so the error will return. The only way to resolve it is to enter the correct option codes for the indoor unit model.

If the fix is simply re-entering the correct option codes, the cost is primarily a service call and labor fee, which typically ranges from $75 to $200 depending on your location and the technician's rates. If the error was caused by a failed control board that also needs replacement, parts and labor combined could range from $250 to $600 or more. Getting a diagnostic estimate before authorizing any parts replacement is recommended.

Clearing E163 requires entering the correct remote controller option codes for your specific indoor unit model through a service-level menu. Accessing these menus and knowing which codes to enter requires model-specific technical knowledge. Most homeowners will need a qualified Samsung HVAC technician to complete this correctly, as entering wrong values can cause further errors or improper unit operation.

E163 is a configuration fault that typically prevents the indoor unit from operating normally, so the system may not run at all while this error is active. There is no immediate safety risk from the error code itself, but you should not attempt to bypass the fault. Contact a qualified technician to correct the option settings before using the unit.
