After a few years of using your refrigerator at home, you will find that its cooling effect is not so good. In the past, some food was still good after a week. It was fresh and did not change at all. But now it seems that the things put in in the morning will have a fishy smell in the afternoon, and even moldy after a longer time. So what is the reason for this?
Everything has a service life. If it has been used for too long, its performance is certainly not as good as before. But if it's a new refrigerator you just bought, what's the reason? However, when we encounter these situations, what should we do?
Open the door of the refrigerator and check whether the light in the box is on to determine whether the power of the refrigerator is connected. If the light is not on, use a pen or multimeter to check whether there is electricity in the power socket and whether the power plug of the refrigerator is well connected.
Use a multimeter to check whether the power supply voltage is lower than 187 V, because the normal operating voltage of the refrigerator is 187v-242v according to the national standard (unless otherwise specified by the manufacturer), the compressor of the refrigerator below 187 V cannot be effectively started normally.
When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is turned on. Only when the low temperature switch is turned on can the temperature controller be forced on. First of all, the refrigerator thermostat is installed in the freezer. The temperature of the refrigerator does not reach the temperature required by the thermostat, so it does not stop.
If the refrigeration compressor is shut down day and night, it is impossible to cause the refrigerant temperature limit. Most of this phenomenon occurs in air-cooled refrigerators. The reason is that the flower frost device of evaporator in refrigeration room is broken, resulting in ice blockage. Also can not rule out the air cooling fan broken, and the refrigerator too many items will plug the air outlet, causing poor cooling effect.
The temperature of the freezer of the direct cooling refrigerator is automatically adjusted with the temperature adjustment of the freezer. You can lower the temperature of the freezer. Generally, the temperature of cold room is 4-10 ℃. Note that the larger the number of the temperature controller, the lower the temperature, the larger the number in summer and smaller in winter. In addition, often open the door of the refrigerator, there are many items in the refrigerator, resulting in the refrigerator does not refrigerate or the refrigeration effect is not ideal.
After reading the above content, you should have a clearer understanding of why the refrigerator's freezer doesn't refrigerate. If similar situations happen to the refrigerator in the future, I believe that with your own efforts, you should be able to find out the reason. But at the same time, we should also pay attention to the use of refrigerators, so that they can be used for a longer time.
