This is a "what to look for" type thread more so than anything else.
The Samsung RS fridge/freezer units seem to been prone to condensor fan motor failure, which causes a number of issues after the fact.
The fan is all plastic, and the top of the shroud warps over time causing the fan blades to hit the shroud and stall the fan.
The fridge will continue to function correctly, however the stalled fan will cause the fan controller to fail, there is a 1000uF 35v electrolytic capacitor on the main board that fails, meaning just replacing the condensor fan motor will not always fix the problem.
The condensor fan motor is a 12v DC brushless motor. I replaced this with a 230v AC ball bearing fan with an aluminium housing to avoid future failures.
I wired this fan into the compressor relay back at the main controller board.
It moves more air and is quieter.
The heat generated by the lack of a cooling fan and the compressor running most of the time has caused the compressor split-phase capacitor to run hot and fail. In my unit, it is a 5uF 400v aluminium motor run capacitor, and mine was very swollen, and reading 0.01nF, meaning its basically completely rooted.
This will likely affect any model of Samsung fridge/freezer, certainly the RS Series, and can generally be repaired easily.
If the door seal surfaces are very warm, this should be checked by a qualified person.
