SAEDNEWS: The refrigerator and freezer are among the most important and widely used household appliances, so we should follow the necessary tips and recommendations to properly maintain and take better care of this electrical appliance.
According to SAEDNEWS, Refrigerators and freezers are considered essential appliances in every household as they help prevent the early spoilage of food items. Domestic refrigerators, freezers, display refrigerators, and other cooling devices all operate on the same system and have similar structures, and they all require certain maintenance tips, which we have mentioned in this section, so please stay with us.
Do not place hot food inside the refrigerator because it will warm up the interior space and reduce the cooling efficiency. As a result, frost and ice may melt and drip along with contaminants onto the food, leading to food contamination.
In refrigerators that do not have a freezer on top, the lower shelves are colder than the upper shelves because cold air is heavier than warm air and therefore moves downward, while warm air rises. For this reason, the upper shelves have less cooling. Also, items placed in the refrigerator door are exposed to outside air every time the door is opened and closed, so they receive less cooling compared to other parts of the refrigerator.

Usually, three indicator lights—green, red, and yellow—are used in freezers. The green light shows that electrical power is being supplied to the freezer. The red light, which should normally be off, indicates that the cooling process is not working properly, possibly due to a thermostat malfunction.
For the yellow light, there is a switch that connects the system directly to ensure sufficient cooling so that the red light turns off. When this switch is turned off, the yellow light also turns off.
Do not place your refrigerator or freezer near heat-emitting appliances such as stoves, water heaters, or radiators, and avoid direct sunlight. There should be at least 20 centimeters of space between the refrigerator or freezer and the wall. Also, make sure the appliance is placed on a level surface; otherwise, the door may not close properly.
When buying a refrigerator, pay attention to the energy label and choose models that have lower energy consumption and higher efficiency.
The temperature inside the refrigerator should be about 3°C above zero, and the freezer temperature should be 3 to 4°C below zero. Incorrect thermostat settings can cause food spoilage or freezing and also increase energy consumption.
After moving a refrigerator, wait two to three hours before connecting it to electricity.
If the cooling performance is good but the freezer’s red light turns on, the indicator wiring may be faulty or short-circuited.
In all seasons, especially in summer, never leave the refrigerator or freezer door open for a long time and avoid opening it too frequently.
