I have three units and one has a clicking sound when it’s off. The other two make zero noise. This has nothing to do with defrost because it’s 85 degrees outside. Today I did the self cleaning and also cleaned the filter. The unit cycled through the cleaning and turned itself off. Still hearing CLICK CLICK CLICK. I also checked outside where the fans are and everything was off there too.
This forum was set up several years ago so customers could help other customers with the smartthings home automation platform, so I’m not sure people here can help you much. That sounds like just an air conditioner issue.
You might get a more helpful response if you try the official Samsung appliances forum. That one is staffed by Samsung employees.
