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.
While we're talking about food safety and temps let's talk about the ideal refrigerator temperature, 35-40 F (1.8-4 C). This range slows the growth of bacteria without risk of freezing foods. Regardless of what anyone says in terms of saving electricity do not turn your fridge thermostast any higher than 40 F (4 C).
