When the refrigerator is used for a long time, there will always be a thick frost on the frozen layer. Frost not only makes the refrigerator consume a lot of electricity, but also is not conducive to food preservation, and sometimes even the refrigerator door can't be opened.

Frosting in the refrigerator not only wastes space, but also hinders the heat exchange on the evaporator surface, resulting in poor refrigeration effect and more and more electricity consumption.

Therefore, when the frost layer on the surface of the freezer reaches about 5mm, it is necessary to defrost.

To be on the safe side, before defrosting, be sure to unplug the power and take out all the food in the refrigerator.

Refrigerator defrosting

1, hot water defrosting

The stainless steel basin is filled with hot water and then put into the refrigerator. The temperature of water is about 70 degrees Celsius.

Because stainless steel conducts heat quickly, the ice layer melts more easily. After a period of time, the ice in the refrigerator will melt.

Although the speed is not very fast, the effect is very good. Finally, we can dry the refrigerator with a towel.

2, plastic wrap layer

We can put a plastic wrap on the refrigerator. In this way, if there is ice in the refrigerator, just take away the food in the refrigerator and gently pull the plastic wrap, and the ice will easily fall off.

The refrigerator will become very clean immediately, isn't it convenient?

Step 3: hair dryer

Empty the refrigerator first, and then unplug it. Then, blow the air outlet of the hair dryer onto the ice, and wipe off the melted water with a towel while using the hair dryer.

Through this simple operation, you can quickly clean the ice in the refrigerator, which is very convenient.

Having said so many ways to de-ice, the most important thing is prevention, so we should also understand the reasons for freezing all the time.

Causes of freezing in refrigerator

U 1, refrigerator temperature is too low.

Usually the correct way is to adjust the temperature of the refrigerator to 4-8 degrees.

If the temperature of the refrigerator is set too low, if there are drinks or cans in the refrigerator, once the liquid flows into the packaging box, it is easy to cause icing problems.

2. Temperature controller failure

The temperature in the refrigerator is kept constant by the thermostat. If the temperature controller fails, the compressor will stop working for a long time.

In this way, if the temperature in the refrigerator continues to drop, it will cause the refrigerator to freeze.

3. The refrigerator door is not closed.

It freezes easily in the refrigerator. Severe freezing sometimes makes it impossible to open the refrigerator door

At this time, many people will think that there may be something wrong with the refrigeration system of the refrigerator. In fact, under normal circumstances, it is very likely that there is a problem with the refrigerator sealing strip.

If the sealing strip on the refrigerator door at home is not tight, it will also cause the air outside the refrigerator to flow into the refrigerator. Because it will condense into ice when it meets low temperature.

Moreover, the sealing strip of the refrigerator is prone to aging problems because it has not been replaced for a long time, which leads to poor sealing performance of the refrigerator and icing.

How to tell if there is a problem with the refrigerator sealing strip?

It's simple. A piece of A4 paper can be used to test whether the sealing ring is tight.

A4 paper test sealing strip.

Clip a piece of A4 paper on the refrigerator door and pull it out. If it is easy to pull out, it proves that the sealing ring of the refrigerator is loose.

If you can't even hold a piece of paper, the cold air in the refrigerator will easily escape.

Because the sealing ring of the refrigerator door is aging, it will lead to the refrigerator door not being closed tightly, and it will consume a lot of electricity and cannot be cooled.

This problem can also be solved with a hair dryer.

Use a hair dryer

Practice: Clean up the aging parts of the sealing strip with a wet rag first, because there are likely to be some dust and impurities attached to the sealing strip in these places.

Make the rubber strip not smooth and uneven, thus affecting the sealing performance, so wipe off these impurities with a rag first.

After the impurities are wiped off, blow on the aging part of the rubber strip for about 1~2 minutes with the hot gear of the blower;

Then you will find that the sealing strip has softened. When the sealing strip becomes soft, immediately adjust the sealing strip by hand to make it smoother and more suitable for refrigerator use.
