Cold storage temperature SMS alarm

The alarm of this refrigerator keeps ringing, and the temperature in the freezer shows-18℃. The reasons are too much food stored in the freezer, the refrigerator door is not closed tightly, the refrigerator refrigerant leaks, the thermostat is faulty, the motor is overheated or the compressor is faulty.

1. Too much food is stored in the refrigerator. When designing the freezer, an object placement value will be designed, and if the volume and weight exceed the set value, an alarm will be given.

The refrigerator door is not closed. If the refrigerator door is not closed correctly or the freezer door is opened for a long time, there will be an alarm sound prompt. It is recommended to close the door again and be careful not to open the freezer door for a long time.

3. Refrigerator refrigerant leaks. If the refrigerant in the refrigerator leaks, the temperature in the refrigerator cannot be effectively controlled, and an alarm state will also occur. The temperature of the freezer will rise slowly, which will affect the refrigeration effect.

4. The thermostat fails, and the frost water in the refrigerator flows into the thermostat, which may short-circuit the thermostat contact and the box, causing electric leakage. It is recommended to defrost regularly and wipe off the accumulated water in the box frequently to prevent frost water from flowing into the thermostat.

5, motor overheating or compressor failure will cause the alarm to ring all the time.
