What should I do if the hot and cold box does not work?

First check whether the status indicates whether it is normal (models with refrigeration and heating indicator Lights); if the indicator light is not bright, or the indicator light is sometimes light and sometimes not bright, mostly the problem of power connection.Can be solved by the following methods:

1. The main power switch on the car is not turned on, because on most vehicles, the key switch is turned on before the smoke socket will be powered on.

2. For the situation where it is too loose, you should be inserted slightly;

3. Smoke sockets or warm and warm box electrical line plugs are dirty, and the refrigerator must be connected after cleaning. Otherwise, it will cause overheating due to poor contact.

4. The fuse in the cigarette socket or the warm and warm box electric source line is burned, and the same model of the specifications should be replaced.

5. The cooling and cold box refrigeration heat conversion switch caused poor contact due to dirt.You can remove the power first and quickly mobilize the switch back and forth several times. You can also clean or send it by yourself.

6. View whether the cooling and warm box heat dissipation fan is Running normally. The fan does not turn or the speed is too slow. The heating box will not be able to refrigerate, but the heating function is normal.

7. When the power supply and switch are no problem and the fan is normal, it may be that the refrigerator is damaged and the maintenance point must be replaced.

The cooling effect of semiconductor refrigerators is not good, how to solve it?

If the extension line is too long, the input voltage will be too low, which will affect the cooling effect.

Poor ventilation can also affect the refrigeration effect, you can adjust the positioning position;

Too much dust affects heat dissipation: leading to poor refrigeration.You can guide the dust on the radiator and the fan on the instructions.

For products with fans inside the warm and warm box, keep the air offer open.

Slow refrigeration: You can put drinks or foods in the home refrigerator and refrigerate before putting it in the warm and warm box. The temperature in the box can maintain it at 15 C-20 C than the ambient temperature after plug-in.

precautions for the use of semiconductor refrigeration products:

Semiconductor electronic boxes can only cool or heat, cannot make ice, cannot be used to store frozen foods such as ice cream, and do not have a refrigerator -like refrigerator like a compressor refrigerator.

The semiconductor electronic box can only be reduced to a temperature lower than the ambient temperature of 20 C-25 C, and the minimum energy refrigeration to 5 C, but it does not mean that when the ambient temperature is 10 C, the box can be reduced to -10 C.(When some models are lower than 15 degrees, there may be frosty)

Please keep the ventilated port and heat dissipation holes in the Car refrigerator, and pay attention to cleaning the dust on the fan or dust cover in time;

Do not stuff the items into the Car refrigerator's heat sink and air inlet pores, and the Car refrigerator should be away from the heat source.

When the heating function and the refrigeration function are converted, the power must be turned off, and the refrigerator is started after 5 minutes.

When cleaning the Car refrigerator, turn off all the power supply, do not use hard objects and powerful cleaners to clean the refrigerator.

When the semiconductor refrigeration products are large or storage of moisture -containing items, condensate water can also be produced, and you can wipe it.

How long is the service life of the semiconductor refrigerator?

The service life of the semiconductor refrigerator is generally about 3 years (note: the normal service life of semiconductor refrigeration tablets is more than 100,000 hours, and the life of components such as fans is generally 1 to 3 years), which are different due to different use environment.
