The role of refrigerators in our lives is self-evident, but many friends who are under budget or living in rental housing will choose second-hand refrigerators at very low prices. There are a lot of posts on the Internet that sell or transfer used refrigerators. Some say they want to move, so they sell at low prices, while others are eager to pursue new trends. Old refrigerators are cheaper and cheaper to sell. However, if you accidentally encounter some refurbished second-hand refrigerators, it is difficult to guarantee the quality and safety of use. Therefore, if you really need to buy a second-hand refrigerator, you need to pay attention to the following points.
First, let's take a look at the purchase time record of the refrigerator. The service life of the refrigerator is usually 10 years to 15 years. It is not recommended to look at it beyond this period.
Secondly, check the inside and outside of the refrigerator for any traces that have been repaired. Pay special attention to whether the compressor has been opened. If the compressor can be seen to open, such second-hand refrigerators are best not to buy. Because of the repaired refrigerator, the possibility of being bad again is relatively high, so check it carefully.
How the cooling effect is also necessary to check, can not just look at the appearance of a good deal to buy directly. The simple method is to energize the refrigerator for more than half an hour. See how the refrigeration and freezer cooling effect of the refrigerator is. If the cooling effect is good, the refrigerator is not bad.
The details are also indispensable, such as the tightness of the refrigerator door. The airtightness of the refrigerator is not enough, the air-conditioning is easy to run off, and the cooling effect is not good. Excessive hot air enters the refrigerator and can easily cause water to accumulate in the refrigerator. If you find that the refrigerator door is not strict, try not to buy it. When testing, you can use a piece of paper on the door seal and close the door without falling.
In addition, we also need to pay attention to the noise of the refrigerator compressor. If the noise is relatively large and the refrigerator is oscillating as a whole during operation, this means that the compressor is aging, and it is best not to buy it. In addition, put your ear on the wall of the freezer. If you hear a smooth sound like running water, the sound is stable. If the sound is short, it means there is little or leaking. The general refrigerator compressor will start every 5-10 minutes. If you look at the refrigerator too often, it means that the compressor of this refrigerator is faulty. It is best not to buy it.
There is demand, there is a market, and with the low price, the consumer market of second-hand refrigerators is very huge. If you really want to buy a second-hand refrigerator, you should give priority to the big brand, not repaired, use a refrigerator with a short period of time, of course, try to buy a second-class refrigerator with energy efficiency. Under normal circumstances, as long as the first user is used reasonably, second-hand refrigerators generally do not have large quality problems.
