A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 Â°C (37 to 41 Â°F).emperature settings for refrigerator and freezer compartments are often given arbitrary numbers by manufacturers (for example, 1 through 9, warmest to coldest), but generally 3 to 5 Â°C (37 to 41 Â°F) is ideal for the refrigerator compartment and â18 Â°C (0 Â°F) for the freezer.
Recommended temperatures Answer: The temperature range in a Sub-Zero with an electronic control panel is 34Â° - 45Â°F (1Â° - 7Â°C) degrees in the refrigerator and -5Â° to 5Â°F (-20Â° to -15Â°C) degrees in the freezer. In units with an electronic control panel, the factory settings of 38Â°F (3Â°C) in a refrigerator and 00Â°F (-18Â°C) in a freezer are ideal food storage temperatures as they cover most foods. Setting the temperature higher or lower than factory settings will cause the unit to run more or less, according to set temperature.
