Outdoor Unit Control Board
Fault Code 179 is a specific diagnostic for a total communication failure at the outdoor unit. In central split systems, the outdoor control board's communication transceiver is exposed to higher thermal variance and electrical noise than the indoor components, leading to premature failure of the RS-485 serial interface logic. Replacing the main control board restores the integrity of the ABCD bus physical layer.
