Refrigerator is a household appliance that almost every family has nowadays. However, not everyone knows how to use the refrigerator correctly. The phenomenon of frost in the freezer is the appearance of white layers of snow or soft ice, which accumulate thickly on the walls of the fridge. Moreover, more seriously, this frost layer can directly attach to the food stored in the fridge.
The causes of this phenomenon are the temperature of the fridge being too low, the storage of the fridge being overloaded, and the temperature sensor of the fridge being broken. In addition, there may be some less common causes such as a faulty thermostat, a blown fuse, a burned motor coil, a broken heating resistor, a dry oil-free gear clamp, dirt or corrosion after long periods of use, or a refrigerator that is not properly ventilated.

Is frost in the refrigerator a problem?
Due to the refrigerator’s temperature being much lower than the outside temperature, many people assume that this is a normal occurrence. However, in reality, according to evaluations from long-standing electronic device manufacturers, distributors, and repair services, if this phenomenon continues for a long time, it will affect the operational efficiency of the refrigerator.
When the refrigerator has a thick layer of frost, the cooling capacity of the appliance is reduced because the areas that propel cold air are blocked, leading to low performance and inadequate food preservation. Especially for refrigerators storing many fresh foods, the risk of food spoilage is significant. Additionally, the thick layer of ice and frost also narrows the interior space of the refrigerator, causing a loss of storage capacity.

How to deal with the ice and frost in the refrigerator
To proceed with the treatment, first unplug the refrigerator for safety.
Remove all the food from inside the refrigerator.
After unplugging, which means that the refrigerator has stopped receiving power, after a few hours, the frost layer will melt and turn into water. Then, use a soft, dry, clean cloth with good water absorption to start wiping away the water from the ice and melting frost. To facilitate the process and ensure hygiene for the floor area, especially wooden floors, you can place newspapers around the refrigerator area. Once the cleaning is relatively completed, leave the refrigerator open for a few more hours.
If the thick frost shows no signs of melting, users can apply some additional methods:
– Use a hairdryer to blow into the refrigerator and affect the frost layer inside the fridge. When performing this method, it is important to keep the hairdryer away from the refrigerator walls and parts to prevent water damage. A hairdryer can be combined with a scraping tool or a kitchen knife. During the process, wear gloves for safety.
– Use a fan to blow continuously into the refrigerator; place a hot bowl or several bowls of hot water inside the refrigerator and then close it to let the hot air melt the ice and frost…
– Use a hot cloth and alcohol: The alcohol here that you can use is ethanol, combined with a little salt. In this case, the salt replaces the water molecules, making it impossible for water and ice to coexist at the freezing point. Meanwhile, the ethanol significantly reduces the freezing point of water, to the point where it is not cold enough to freeze.
You can also mix hot water and a large amount of salt, then soak a piece of fabric in the solution, then immerse it further into the alcohol. Next, use that fabric to wipe the ice blocks inside the freezer compartment. At this time, the ice blocks will gradually melt away from their positions.
When encountering severe cases that cannot be self-remedied at home, it is best to contact professional repair technicians and warranty centers for refrigerators.
