Yourlooks like a simple device . Connect it, let it cool down, adjust the temperature of the fridge and freezer and fill it with food. From then on, it should do its job, but things are not always that easy or simple.
Something as simple as how you organize your fridge can affect how long your food stays fresh. And to make sure your fridge and freezer are set to the right temperature is more important than you might think.
The ideal temperature for refrigerators and freezers
It's not just a cool or freezer that does not cool to the right temperature that spoiled food is a problem. Foodborne diseases are more of a threat.
To prevent food from being prematurely spoiled and safe for human consumption, the US Food and Drug Administration (FDA) recommends keeping the refrigerator at least 4 degrees Celsius. Your freezer should be set to 0 degrees Fahrenheit (-18 degrees Celsius). They want to avoid the "danger zone" between 40 degrees and 60 degrees Celsius, where bacteria can quickly grow on food and make you sick.
Some modern refrigerators have built-in digital thermometers in the fridge, freezer or both. With these you can set exact temperatures. Many refrigerators only have dials with a numeric scale or one that goes from "cold" to "coldest". No matter what type of controller you have, it's best to check the temperature regularly with a separate thermometer to cool the equipment as they should, but also check the accuracy of the built-in thermometer.
How to check the temperature of freezer and refrigerator
The thermometer used to control the temperature plays a role. For a refrigerator, you should use a pear or candy thermometer. You can also use an instant readable meat thermometer.
To check the temperature of a refrigerator, it is best to use food or liquids that have been in the compartment for at least 24 hours. The most common practice is to put a glass of water in the fridge (but not in the door) and leave it for a day. Then place the thermometer in the glass to get a reading. If you use a thermometer that is read immediately, you will have your reading immediately. For other types of thermometers, close the door and check it in a few hours, after the inside temperature of the refrigerator has stabilized and the thermometer has received a reliable measurement.
Since the inside temperature of a refrigerator does not work If you keep it consistent all the time, you can repeat the process and keep the glass of water in various places in the refrigerator.
For the freezer, a glass of water does not work. Instead, simply place the thermometer between two already frozen foods in the center of the freezer in the freezer. You can also put the thermometer in ice cream. Close the door and wait at least 12 hours for the thermometer to be read.
When adjusting the temperature of the refrigerator or freezer, you should give it at least 24 hours for the new setting to stabilize to another reading. Repeat the process until you reach the desired temperatures.
