On Samsung’s US site the RT18DG6500SR is the Bespoke AI Top Freezer All-Around Cooling Garage Ready | 18 cu.ft., a 18 cu. ft. top-freezer refrigerator. The RT18DG6500SR is a top-freezer cabinet with one evaporator behind the freezer wall, so a frost sheet on that wall and a warm lower section almost always mean the defrost circuit has stopped clearing the coil.
On the RT18DG6500SR, an OF OF or scrolling-bar display is checked first – it is Cooling Off mode, not a problem – and only then does the visit move to the fan, defrost and control tests with the refrigerator isolated at the breaker.
