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.
Average temperature of a refrigerator is 35 - 38 degrees and -18 Â°C (0 Â°F) for the freezer. A household refrigerator should be maintained between 34 and 40 degrees Fahrenheit - just above freezing to maintain food quality but low enough to inhibit bacterial growth.
