Climate class
The ambient temperature range a refrigerator is designed and rated to operate in.
Climate class (SN, N, ST, T, or the combined SN-T) tells you the room-temperature range a fridge or freezer is engineered to perform correctly within. SN covers 10 to 32°C, N covers 16 to 32°C, ST covers 16 to 38°C, and T covers 16 to 43°C; SN-T spans the full 10 to 43°C range, which suits most homes including unheated garages or hot climates. Running a fridge outside its rated climate class, for example in an unheated garage in winter, can mean it fails to reach or hold its target temperature.
