I think you meant the evaporator; ice on the condenser would mean it's running backwards! Was it advertised as having automatic defrost/"frost-free"? Not all are. If you live in a humid climate, even the auto defrost may not be sufficient to remove all the frost.
I'll certainly not correct you! I'm not a pro by any means on HVAC and chiller technology. I just came up with a solution, albeit not a "good" one. I do know one thing; I'll never buy Samsung again.
I know, whatever it's called, has copper pipes hooked up to a heatsink, with a blower fan that spreads the chilled air. It's in the bottom of the fridge side, inside the refrigerator chamber.
The failure mode, which is evidently widespread online, is that condensation seizes up the fan blower, stops the fan, and temps rise gradually.
