The refrigerator freezer is not cooling

After using your home refrigerator for a few years, you will find that its cooling effect is not so good. In the past, if I put some food in there, it would still be good after a week, very fresh and without any taste changes. But now, it seems that things put in there in the morning will have a fishy smell in the afternoon, and even get moldy after a while. So what is the reason for this?

Everything has a service life. If you use it for too long, its performance will definitely not be as good as before. But if this happens with a newly bought refrigerator, what is the reason? However, what should we do when we encounter these situations?

Open the refrigerator door and check whether the light inside the refrigerator is on to determine whether the refrigerator is powered on. If the light is off, use a tester or multimeter to check whether there is power in the power socket and whether the refrigerator's power plug is properly connected.

Use a multimeter to check whether the power supply voltage is lower than 187 volts, because the normal operating voltage of refrigerators according to national standards is 187V-242V (unless otherwise specified by the manufacturer). If the voltage is lower than 187 volts, the compressor of the refrigerator 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. The temperature controller can be forced to start only when the low temperature switch is turned on. The reason why the refrigerator does not refrigerate is that the refrigerator thermostat is installed in the refrigerator compartment. The temperature in the refrigerator compartment does not reach the temperature required by the thermostat, so it does not shut down.

If the compressor does not stop day and night, the freezer may reach the extreme refrigeration temperature of the refrigerant. This phenomenon mostly occurs in air-cooled refrigerators. The reason is that the defrost detector of the refrigerator compartment evaporator is broken, causing ice blockage. We cannot rule out the possibility that the air-cooling fan is broken, or that there are too many items in the refrigerator that block the air outlet, causing poor cooling effect.

The temperature of the refrigerator compartment of a direct cooling refrigerator is automatically adjusted along with the temperature of the freezer compartment. You can simply lower the temperature of the freezer compartment. Generally, the normal temperature in the refrigerator is 4-10 degrees. Note that the larger the number on the temperature controller, the lower the temperature. The number should be larger in summer and smaller in winter. In addition, the refrigerator door is often opened and there are many items in the refrigerator, which causes the refrigerator to not cool or the cooling effect is unsatisfactory.

After reading the above content, you should have a clearer understanding of why the refrigerator's freezer does not refrigerate. So if a similar situation occurs in 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 how to use the refrigerator so that we can use it for a longer time.
