1. Compressor cannot start

① Confirm if the freezer has power supply and close the door of the freezer. If the internal light is bright, the freezer will have power. If the light is not on, you can check if the main power supply has power and if the fuse is present (not all refrigerators have fuses). Finally, check if there are any issues with the thermostat contacts.

② You can check if the compressor is burning out, if the motor coil is burning out, and finally check if there is a starter. Sometimes the overheat shield is activated, so it takes about a minute for the compressor to cool down before it can be fully started.

③ The thermostat cannot be reset, and the contacts are sintered together, creating a problem of not falling off.

2. Temperature control too low

When handling equipment temperature refrigerators, the temperature is not fixed, so even if it is moved to a certain position, it cannot be adjusted as usual. However, the internal temperature change is due to the low temperature adjustment program of the thermostat in summer, which continuously forms the refrigerator. If the temperature of the freezer is too low, the thermostat can be rotated counterclockwise or the number can be turned down. Handling computer freezers has great advantages in this regard.

3. Cold storage room wall frost

The temperature controlled freezer of the processing machine, especially at high temperatures, causes frost on the walls of the refrigeration room, resulting in a thick frost layer that does not shut down the freezer. The biggest reason for this situation is that the temperature adjustment of the thermostat is too low, the food in the cabinet is not well stored, opened too much, and the insulation of the cabinet door is not good. First, turn off the freezer, lower the frost on the freezer wall, adjust the position of the thermostat, check the door lever, etc., and then restart from scratch. This is the key. If the refrigerator is functioning properly, it is necessary to handle the punishment properly. If there are problems with the refrigerator itself, it is necessary to find the manufacturer for disposal

4. The thermostat in the freezer is malfunctioning

Due to the lack of flexibility of the refrigerator temperature controller itself, it can also form a refrigerator malfunction. However, this malfunction does not only occur in high temperature situations, but also in various temperature situations. However, the situation is more important in high temperature situations. The main reason is that the machine's temperature controller leaks fluorine, or the temperature sensing head cannot sense the temperature, and there is a problem with the control circuit board of the computer freezer.

5. Refrigerant leakage from the freezer

In this situation, the initial indication of not cooling the refrigerator is that after a long period of time, the temperature of the refrigerator will rise, gradually starting to not cool, but the compressor of the refrigerator is still working. A good way to distinguish the advantages and disadvantages of the refrigerator is that if the compressor is working, but the two sides of the refrigerator do not have a fever. At this moment, the refrigerator is mostly like this, which can begin to be affirmed.
