CHECK THE TEMPERATURE
It pays off to check the temperature in your refrigerator now and again. Place a thermometer in a glass of water and place it in the refrigerator. Your refrigerator should be between 2ºC to 6ºC. Due to the circulation of air inside your refrigerator, the temperature can vary according to the exact location inside. Generally, it is colder at the bottom and warmer at the top. Therefore, it makes sense to store more sensitive products, such as meat and milk, at the bottom, where it is coolest, and vegetables higher up, where it is warmer. If your refrigerator is very full, for example if you have stocked up for a party, then it is good to set the thermostat to a slightly colder setting.
