What is the reason why the freezer compartment of the refrigerator is not refrigerated? List them one by one
Yesterday, Xiaobian’s refrigerator at home suddenly stopped cooling. When he got up in the morning, he was woken up early and said that everything in the refrigerator was broken. He asked me to go and see what was going on. Xiaobian opened the refrigerator and found that almost everything in the freezer layer has become soft. Isn’t the refrigerator refrigerated anymore? What happened?
Is that wrong? Why can’t the refrigerator be refrigerated suddenly? Is the refrigerator aging? Or other reasons? Later, I thought about it carefully, was it caused by adjusting the refrigerator thermostat last night? Xiaobian carefully checked the temperature controller in the refrigerator storage room.
1. Temperature controller problem
I found that the thermostat can still be rotated and adjusted normally. Is it because the temperature of the refrigerator thermostat is too high, causing the refrigerator to be poorly cooled and the things in the freezer layer will become soft?
So Xiaobian readjusted the thermostat and adjusted it to the highest gear. At this time, the cooling effect was the best. In theory, normal cooling should return to! After waiting for about an hour, I found that the refrigerator was still not refrigerated, and there was no sound of the compressor starting. Is the refrigerator really broken?
2. Compressor thermal protection
When the refrigerator compressor is running at high speed, the refrigerator compressor will not stop running, especially if it is running at high speed for a long time. You will find that both sides of the refrigerator at home will be very hot, which is hotter than during normal refrigeration. At this time, the refrigerator compressor will start working when it is hot and the refrigerator compressor will stop running. At this time, you will not hear the sound of the compressor working normally, because the compressor is in a thermal protection state and the compressor will not run.
This was the reason why the refrigerator in Xiaobian’s home was not cooled this time. A professional air conditioner maintenance technician came to help check. In the end, the reason was that the refrigerator was not cooled due to the thermal protection of the refrigerator compressor. Later, after the refrigerator was cut off to dissipate heat, the temperature controller was restarted and the refrigerator returned to normal cooling.
3. The compressor is damaged
If the refrigerator is not refrigerated, you carefully check whether the light in the refrigerator compartment is still on. If the light in the refrigerator compartment is on normally, it means that the power is normal. If the refrigerator is not refrigerated and the compressor is not working, if it is not thermal protection, it is very likely that there is a problem with the compressor. If there is a problem with the compressor, you can only find a professional refrigerator repairman to repair it.
4. Insufficient refrigerant
Generally, insufficient refrigerant will only occur when the refrigerator has been used for a long time. If there is insufficient refrigerant, problems will occur with the refrigeration effect of the refrigerator. You can open the outer board of the refrigerator compressor and observe whether there is frost on the copper pipe connected to the compressor. If there is too much frost, it means that the refrigerant is insufficient and the refrigerant needs to be added in time.
At present, the refrigerator suddenly no longer cools, and the cooling effect has become very bad. You may wish to carefully check whether these are the above four reasons. Only by understanding the real reason why the refrigerator is not refrigerated can we better repair the refrigerator. The above is a compilation of four common reasons why refrigerators are not cooled. I hope it will be helpful to everyone.
