What's the matter with the low sound and no refrigeration in the freezer?

If the refrigerator is quiet but does not cool, it may be caused by the following problems:

1. thermostat failure: the thermostat of the freezer is an important part to control the temperature. If the thermostat fails, it will lead to the failure of normal temperature control, so that the freezer can not be cooled. At this time, it is necessary to replace or repair the thermostat.

2. Compressor failure: The compressor of the freezer is the most critical component in the refrigeration process. If it fails, it will lead to compressor failure, which will lead to refrigeration failure. At this point, the compressor needs to be replaced or repaired.

3. Refrigerant leakage: The principle of refrigerator refrigeration is to use the circulation of refrigerant to continuously circulate heat conduction between evaporator and condenser to realize refrigeration. If the refrigerant leaks, the refrigeration effect will be affected, and the freezer will not be able to cool normally. At this time, it is necessary to detect the location of refrigerant leakage and repair and fill it in time.

4. Internal maintenance problem: If the drain hole of the freezer is blocked or accumulated water, it will affect the refrigeration effect and cause the freezer to fail to cool normally. At this time, it is necessary to clean up the drainage holes and accumulated water to ensure that the inside of the freezer is dry.

In a word, if the refrigerator is quiet but does not cool, it may be caused by many reasons, so it needs careful inspection and maintenance to ensure the normal operation of the refrigerator.
