I searched the internet on ref noises, nothing mentioned about barking noise but read that such noise could be icy build up in Evaporator fan. Work around is to defrost. Followed that, I turned it off overnight. The next day, turned it on and the noise is gone. Just to reach out to BITOGers don;t buy a new fridge yet, or call the service technician$, it's a simple fix
