What temperature should be in the refrigerator

The higher the temperature in the refrigerator, the greater the risk breeding bacteria that can cause food poisoning.

To avoid food spoilage, the US Food and Drug Administration (FDA) recommends make sure that the air in the refrigerator compartment is not warmer than 4 °C.

At the same time, values ​​below 2°C may increase the load on the compressor and waste electricity, but will not provide additional benefits for the shelf life of products.

Thus, the ideal temperature for the refrigerator chamber is from +2 to +4 °C.

How to measure the temperature in the refrigerator

To do this, you can buy an ordinary inexpensive thermometer and leave it on the middle shelf.

When you open the door, the temperature in the chamber changes, especially if the room is hot. Therefore, in order to obtain accurate data, it is better to leave the device inside all night and check the readings in the morning.

As for the thermometer itself, there are several suitable options for the refrigerator.

1. Mechanical

How to adjust the temperature in the refrigerator

All modern refrigerators allow temperature control, but how exactly it is arranged depends on the model.

1. Mechanical adjustment

It is a wheel or adjustment knob located near the light bulb – either on the top panel or on the wall on the right.

The numbers on such regulators do not show the temperature, but the intensity of the cold. The most commonly used values ​​are from one to five or seven. The higher the number, the colder inside.

If the thermometer reads more than 4 °C, move the dial one digit forward (for example, from two to three) and leave it overnight again.

2. Electronic adjustment

Such regulators allow you to set the desired temperature by switching buttons or setting degrees on the touch screen.

Depending on the model, the temperature setting method may differ. For example, some refrigerators require a long press on the touch panel to activate the switch, while others simply touch the desired button. Read the instructions for your model.
