How to set your refrigerator temperature using a manual and electrical control selector
The refrigerator temperature can be adjusted by a control selector which can be manual or electronic. Once you have set the temperature, it will be down to the thermostat to maintain this designated temperature by stimulating the motor and activating the cooling system.
In the following article, we analyse the different structures of the two selectors and the different ways in which they operate, and thus show you how to set the fridge temperature to best meet your needs.
The manual control setting selector is a wheel on which there are (arbitrary) numbers ranging from 1 to 5 (and sometimes 6). The temperature is adjusted logically following the idea that when the wheel is at the lowest position (1) the temperature is less cold, while when at the highest position (5) the temperature is cooler. Therefore according to your needs, by moving the dial between the numbers, you will be able to achieve a more or less cool temperature inside the refrigerator. The temperature range between the lowest and highest numbers is that of 1° C and 7/8 ° C. You are advised to set the temperature to the medium figures in order to avoid malfunctions throughout the year.
Indeed, it may be that during the summer the refrigerator motor has to work continuously whether because you want the food to be cooler, or because the fridge is particularly full or simply due to the fact that the external temperature is higher. This continuous operation causes a layer of ice to form on the bottom wall of the refrigerator. This condition results in high fuel consumption and, with the increase of the thickness of the layer of ice, the desired cannot be achieved. The average position on the dial instead ensures that a constant defrosting take place and that the temperature is maintained regularly.
Depending on the structure of the refrigerator you can find a single switch for both the refrigerator and the freezer or two separate ones. In the first case, the temperature of the refrigerator and freezer are both regulated, although in different ways so that much lower temperatures are achieved in the freezer compartment. In the case of two independent switches, the same operating concept is applied.
In more advanced refrigerators there are two electronically powered buttons that control the temperature of the refrigerator and freezer independently. By pressing the button for the refrigerator displayed on the controller you will see a range of numbers going from 1 to 7, while the freezer control selector displays the numbers from 14 to 21/25 (depending on the model).
In this case, the concept used to set the temperature is completely different to that of the manual controller, in other words the numbers that appear on the selector are exactly equivalent to the temperature that you set within the fridge and freezer. To be more clear, when you set the refrigerator temperature to number 3 on the dial it means that you will have a temperature of 3 ° C inside the appliance, rather than set 7 ° C and so on. The same thing applies for the freezer where 25 is equivalent to -25 ° C. On the display is the icon ° C is usually shown to indicate the refrigerator compartment and - ° C for the freezer compartment.
The ideal temperature for the freezer is between -21 ° C and -25 ° C, while for the refrigerator it all depends on the user’s needs, that is whether they want the food to be more or less cold. It is generally said that that setting your fridge at temperatures as low as 1 ° C tends to make food extremely cold, if not frozen.
To sum up, when using the manual selector you need to turn the dial closer to the number five to have a colder temperature, whilst the opposite applies when using the electronic selector. When setting the temperature electronically you need to decrease the number (to a lower degree such as one) in order to achieve a cooler temperature.
