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.
Hereâs the short answer: The ideal refrigerator temperature, measured in the middle of the middle shelf, is between 35 and 38 degrees. Your fridge needs to be warm enough so your food doesnât freeze (32 degrees) but not so warm that it crosses into the bacterial danger zone (above 40 degrees). So a number somewhere around the middle of those two bookends makes sense. You probably know that some places in the refrigerator are warmer than others.
