Some problems and solutions of car refrigerators
1. The refrigerator is noisy
The problem of high noise in semiconductor refrigerators is generally on the fan, which directly affects the cooling effect of the semiconductor refrigerator. The sound of compressor refrigerators must be 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 noise of the fan is naturally loud; the second is to 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 refrigerator can not only improve the quality of life in the car travel, but also embellish the taste of the home bedroom, because the car refrigerator can be used as a supplement to the home refrigerator in addition to the car, and can be used in the bedroom and living room.
2. No refrigeration
For semiconductor refrigerators, firstly check whether the fan is running; secondly, check the product current. If it's close to 5 amps, it's safe to say the PCB or cutout is fine; if there's no current, check the voltage at the Peltier connection on the PCB. If it shows 12V or higher, then the PCB and thermal fuse are good, and it is recommended to replace the Peltier element. If there is no voltage, check the fuse to determine whether it is the PCB or the fuse is broken. If these aspects are checked and there is no problem, you have to find the manufacturer for repair. Of course, to check these items, you must have tools. If you don't have tools, you can only be in a hurry. Compressor refrigerators are not recommended for in-depth inspections, because the technology of the compressor is more complicated.
3, the machine has been cooling
This situation of non-stop mainly occurs in customers who shop online, because the courier company is not responsible for the delivery of online shopping. The temperature can only be kept cool. If the crack is not big, you can seal it with glue or something by yourself. If the crack is too large, it is probably not scrapped and has to be repaired by the manufacturer. Therefore, I remind online shopping friends that you must check carefully when you receive the goods. Don't feel that checking in front of the delivery person is distrusting him. In fact, this is completely to protect your own rights and interests.
4. High power consumption
Unless you buy cheap or imitation products, regular brand products focus on power consumption when they are designed and produced, and they are generally not that high. Another reason is that the refrigerator does not have a low-voltage protection device. After the car is turned off, you forget to turn off the power of the refrigerator. The refrigerator has been working all the time, and it has been consuming the power on the car battery, which directly causes the car to fail to ignite when it is started again. It is recommended to buy a car 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 refrigerator to transport pharmaceutical preparations, because of the high temperature requirements, it is best to measure the temperature in the box before the car refrigerator is officially used. However, when measuring, it should be noted that 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 home refrigerator, the temperature on the side of the door is not the same as the temperature on the inside of the refrigerator.
