It will be easy to adjust the temperature to the recommended 5 ° C or lower when your fridge has a digital temperature monitor. However, many fridge models don't have a digital temperature display for temperature regulation. So, you will have to guess the fridge temperature in such a situation.
Use a fridge-thermometer to monitor the actual temperature inside your refrigerator once you have set the controls to the proper temperature. The temperature on the various shelves within your refrigerator will vary so that your refrigerating thermometer reads slightly different across various areas. It is recommended that the coldest place in the fridge must be below 5 ° C. In other words, it would also help to make sure by little organization that food doesn't spoil in your fridge. Surprisingly, it is not always the safest way to store milk near to the fridge door, as this is the warmest spot. Instead, store canned beverages and glass jars such as mustard or jam using the shelves inside the door.
Most of us are well aware not to put hot food in the fridge directly, but you might have forgotten to remember how warm your chilled food has become when you get it from the supermarket. As per reports, it is found that during the journey from the shop to the refrigerator the temperature of certain items can be increased by up to 11°C and can take 15 hours to re-attain a healthy temperature. You can do a favor to your fridge by using a plastic shopping bag for chilled food when you go to the weekly store.
To maintain a safe temperature your fridge needs air circulation within it. Too tightly pack food together does not allow the air to pass freely inside the refrigerator. If your refrigerator has been packed for a party and is looking too full, take the products out that don't have to chill constantly (such as wine, beer or fruits, and vegetables) until there is more space.
Keep door opening to a minimum
Opening of the fridge door frequently and for a longer time will increase the temperature in the fridge by a few degrees. The longer the door is open, the more energy your refrigerator uses to lower the temperature to below 5°C. Maintain a minimum of the door opening to protect your food within the refrigerator and retain your energy bills.
