To check the temperature of a refrigerator, it’s best to use food or liquid that has been in the compartment for at least 24 hours. The most common practice is to place a glass of water in the refrigerator (but not in the door) and let it sit for a day. Then place the thermometer in the glass to get a reading.

The United States Food and Drug Administration (FDA) mandates that refrigerated products must be kept at 41 Degrees Fahrenheit or lower.

Freezer temperature ranges are generally much colder.How often should a walk in refrigerator be cleaned?1.
