Causes and solutions of refrigerator door not closing tightly

Have you ever had a situation where the refrigerator door doesn't close tightly? Some people find that the refrigerator door doesn't close tightly when using it. What should they do? The refrigerator door won't close because the sealing strip has lost its magnetism. We can replace the seal or use some physical methods to deal with it. The following small series will introduce you to the treatment method of the refrigerator door not being closed tightly. Let us know how to deal with it and see how the refrigerator works.

One. Methods/steps

Insert the hair dryer into the plug board, open the refrigerator door and clean the door seal from top to bottom. Turn on the blower switch and blow gently up and down against the refrigerator door seal. Then try to close the refrigerator door to see if the door seal is more magnetic than before.

If it is better, then continue to blow gently up and down, then close and try until you are satisfied. Another way is to tie the loosely controlled door with a rope and control yourself not to open the refrigerator door overnight.

Second, the working principle

According to the statistical analysis of the Analysis Report on Market Prospects and Investment Opportunities of Refrigerator Industry in China 20 13-20 17, refrigerators have the following nine working principles according to different classifications:

1) compression refrigerator: this refrigerator is provided with mechanical energy by a motor and works on the refrigeration system through a compressor. The refrigeration system is based on the principle that low-boiling refrigerant absorbs heat when it evaporates. Its advantages are long service life and convenient use. 9 1 ~ 95% refrigerators in the world belong to this category. Commonly used refrigerators use a refrigerant named R600 refrigerator A as a heat "porter" to "carry" the heat in the refrigerator to the outside of the refrigerator.

2) absorption refrigerator: this kind of refrigerator can use heat sources (such as gas, kerosene, electricity, etc.). ) as a driving force. The mixed solution of ammonia-water-hydrogen is used to realize refrigeration in the continuous absorption-diffusion process. Its disadvantages are low efficiency and slow cooling, which has been gradually eliminated.

3) Semiconductor refrigerator: It is a refrigerator that produces Peltier effect at the junction by applying direct current to PN semiconductor.

4) Chemical refrigerator: It is a refrigerator that uses some chemicals to absorb heat strongly when dissolved in water to obtain refrigeration effect.

5) Electromagnetic vibration refrigerator: It is a refrigerator with electromagnetic vibration machine as the main power to drive the compressor. Its principle and structure are basically the same as that of the compression refrigerator.

6) Solar refrigerator: It is a refrigerator that uses solar energy as refrigeration energy.

7) adiabatic demagnetization refrigeration refrigerator.

8) Radiant refrigeration refrigerator.

9) Solid refrigeration refrigerator.

Do you know why the refrigerator door doesn't close tightly now? The reason why the refrigerator door doesn't close tightly is that the seal has lost its magnetism. We can blow the seal with a hair dryer. The refrigerator door was not closed tightly, probably because it was not cleaned. We can remove the seal of the refrigerator door for cleaning, and it must be air-dried after cleaning. Before choosing a refrigerator, we should check whether the refrigerator door can be closed tightly. If the refrigerator door is not closed, we can also look for after-sales service.
