Common troubleshooting and maintenance of household refrigerators

Unlike typical household appliances, refrigerator maintenance is highly specialized. However, in daily life, we can also learn how to troubleshoot problems with refrigerators, which is very helpful for everyone.

Firstly, regarding the issue of the refrigerator not cooling, it involves multiple reasons. Firstly, we need to determine whether we have closed the temperature zone ourselves. If not, we need to investigate whether it is a partial failure to cool or if the refrigerator as a whole is not cooling. If it is a partial failure to cool, it is necessary to check the sensors, such as checking the refrigeration compartment, and it may also be a problem with the solenoid valve. The main focus should be on checking the direction change.

If there are no issues with the above aspects, it is generally required to open the refrigerator system for inspection, mainly due to two reasons: refrigerant leakage and capillary blockage. If there is a leak, it needs to be repaired in a timely manner. If it is blocked, the capillary tube should be unblocked in a timely manner. Some repair sites will have professional tools to carry out the work.

Secondly, regarding the issue of poor refrigeration performance of the refrigerator, the simplest way is to first check if the food we store exceeds the food line of the refrigerator, and if so, reduce storage. Then there is the issue of refrigerator cleaning. If the refrigerator is not cleaned for a long time, it will accumulate too much frost inside, which will also affect the cooling effect. Therefore, everyone must pay attention to the cleaning work of the refrigerator in their daily lives.

Of course, if all the above requirements are done well, it is necessary to conduct a systematic inspection of the refrigerator, such as whether the temperature limiter is damaged, whether there is a problem with the compressor's exhaust, and whether the sensor parameters are correct. These all require planned inspection work. There are also many videos online about refrigerator maintenance now, everyone can take a look.
