On Samsung’s US site the RT70F18LRSR is the Bespoke AI Top Freezer All-Around Cooling Garage Ready | 18 cu.ft., a 18 cu. ft. top-freezer refrigerator. The RT70F18LRSR 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.
With the RT70F18LRSR switched off at the breaker, the rear evaporator cover comes off and the fan, the defrost heater and its sensor are measured before any part is ordered; a sealed-system problem is confirmed by pressure and temperature readings, never assumed from a warm cabinet.
