Since the layer of ice inside the freezer prevents proper heat exchange with the outside environment, the motor can overheat. If the motor overheats, its efficiency decreases and energy consumption increases. In addition, overheating can damage the motor and shorten the life of the appliance. Therefore, by defrosting the freezer, you prevent the motor from overheating and protect the appliance from damage that can occur due to excessive heat.
The layer of ice inside the freezer can hinder the circulation of cold air, reducing the absorption capacity of food. If the cold air does not circulate properly, some areas of the freezer can become warmer than others, creating ideal conditions for bacteria to grow and food to spoil. Removing the accumulated ice ensures better circulation of cold air and therefore better preservation of food, thus avoiding waste.
How often should you defrost the freezer?
The ideal time to defrost the freezer depends on the layer of ice that has formed inside the appliance. In general, it is recommended to carry out this process when the layer of ice has reached a thickness of about 3-4 millimeters, as energy consumption can increase by up to 30% at this point. If the appliance is used frequently and a layer of ice forms quickly, it will need to be defrosted more often. On the contrary, with less frequent use, the layer of ice forms more slowly and the frequency of defrosting can be reduced.
How to quickly defrost the freezer without unplugging it?
Of course, the easiest way to defrost a freezer is to unplug it, but how can you do it even when it is plugged in? If you unplug the appliance, there is a risk that the shelf life of the food stored in the freezer and refrigerator will be compromised. Here are the steps to follow to defrost the appliance, even if it is plugged in:
Remove all food from the freezer and store in a cool place
Place a pan of boiling water in it to raise the temperature and collect the water produced during defrosting
Close the freezer and wait for the ice to melt. This way, the heat from the boiling water will help melt the ice faster.
Open the freezer from time to time to let warm air in, which will also help the ice melt faster
Remove any remaining ice with a cloth, towel or sharp object. Avoid using sharp or pointed objects, as they could damage the surface of the freezer and injure you.
Dry the freezer thoroughly.
Close the freezer and wait for the temperature inside the appliance to return to normal before putting the food back in.
