Some Problems And Solutions Of Car Electronic Refrigerator

　　1. The refrigerator is noisy

　　The problem of large noise in semiconductor refrigerators is generally in the fan, which directly affects the cooling effect of the semiconductor refrigerator. If the fan speed positioning and detail processing are not done well, the problem of loud noise will occur. The sound of compressor refrigerators is relatively loud, but there are also compressor refrigerators that have done a good job in compressor noise reduction technology. The first feature of compressor refrigerators is low noise. If the noise is found, first check the fan. The aging noise of the fan is naturally loud; secondly, check the compressor (if there is a compressor). If the compressor sounds abnormal, you have to find the manufacturer to repair it. Choosing a low-noise car electronic refrigerator can not only improve the quality of life of the car traveler but also embellish the taste of the home bedroom because the car electronic refrigerator can be used as a supplement to the household refrigerator in addition to the car and used in the bedroom and living room.

　　2. No cooling

　　For semiconductor refrigerators, first, check whether the fan is running; secondly, check the product currently. If it is close to 5 amps, you can safely say that the Peltier component, PCB, or safety switch is OK; if there is no current, check the voltage at the connection of the Peltier component on the PCB. Then, if it shows 12V or higher, the PCB and thermal fuse are good, and it is recommended to replace the Peltier components. If there is no voltage, check the fuse to determine whether the PCB or the fuse is broken. If there is no problem in these aspects, you have to find the manufacturer to repair it. Of course, to check these items, you must have tools. Without tools, you can only do it in a hurry. Compressor refrigerators are not recommended for in-depth inspection, because the compressor technology is more complicated.

　　3. The machine keeps cooling

　　The non-stop situation mainly occurs to customers who shop online, because the courier company is not responsible for the online shopping and mailing, and the item is dropped badly, causing the cabinet to break, that is to say, the air-conditioning keeps leaking, and the refrigerator has not reached the reservation. The temperature can only be refrigerated all the time. If the crack is not big, you can seal it with glue and other things yourself. If the crack is too large, you may have to find the manufacturer to repair it without scrapping it. So remind friends who shop online, you must check carefully when receiving the goods, and don’t think that checking in front of the delivery person is distrustful of him. This is completely protecting your rights and interests.

　　4. High power consumption

　　Unless it is a cheap or imitation product, the power consumption of regular brand products is always considered when designing and producing, and it is generally not too high. Another reason is that the refrigerator does not have a low-voltage protection device. After the car is turned off, the refrigerator is forgotten to turn off the power supply. The refrigerator keeps working and consumes the battery of the car. This directly causes the car to fail to light up when the car is started again. It is recommended to buy a car electronic refrigerator with a low-voltage protection device, or buy a voltage protection device, or remember to directly power off the refrigerator after parking.

　　5. The actual temperature does not match the displayed temperature

　　For users who use the car electronic refrigerator to transport pharmaceutical preparations, because of the high-temperature requirements, it is best to measure the temperature in the box before the car electronic refrigerator is officially used. But pay attention when measuring, the temperature displayed on the refrigerator display is not necessarily the same as the temperature measured when the thermometer is hung, because the location of the measuring point is different. Just like a household refrigerator, the temperature on the side of the door is different from the temperature on the inner wall of the refrigerator.
