What happened when the refrigerator didn't cool for a day after I bought it? Hangzhou refrigerator maintenance

In this case, first check whether the power supply is normal. If there is no normal power supply or abnormal power supply, it will lead to the situation that the refrigerator will not be cooled after being bought. After eliminating the power supply problem, it may be because the compressor is not working properly, which may easily lead to the refrigerator not cooling. In addition, because the refrigerant in the refrigeration system can not reach the scope of use, it will lead to the problem of no refrigeration in the refrigerator. Suggested solution: 1. If the power supply has poor contact or abnormal power supply, it needs to be unplugged and plugged in again, or contact professional maintenance personnel to adjust the power supply to solve the problem of power supply in disguise. For this newly bought refrigerator, the problem of not cooling may be due to the quality problem of the compressor inside. If it can't work normally, the refrigeration system can't work normally, so it is necessary to contact the after-sales personnel of the manufacturer in time and replace it in time. 3. If the refrigerant is insufficient, it needs professional testing to know whether it belongs to the normal use range. If it is not enough, just replenish it in time and restore normal refrigeration.
