What is the ideal refrigerator thermometer reading during a 12-24 hour run test?

The ideal refrigerator thermometer reading during a 12-24 hour run test should ideally be between 35 to 40°F. This range ensures that the refrigerator is maintaining optimal temperatures for food safety and preservation.

A temperature that is too high increases the risk of spoilage and foodborne illnesses, while a temperature that is too low may lead to freezing and negatively affect the texture and quality of certain foods. The 35 to 40°F range strikes a balance that is widely recommended by food safety guidelines, allowing for freshness while preventing the growth of harmful bacteria.

Temperature readings below or above this optimum range could indicate issues with the refrigeration system or improper loading of the unit, both of which compromise the efficiency and safety of food storage.
