1. thermostat failure: the thermostat is an electronic component that controls the temperature of the refrigerator. If the thermostat fails, it will cause the refrigerator to start again and again.

2. Overload protection: The refrigerator may be overloaded, triggering overload protection, leading to repeated startup.

3. Condenser failure: The condenser is a cooling component in the refrigerator. If the condenser fails, it will cause the refrigerator to start continuously.

4. Power failure: The refrigerator depends on power supply. If the power supply fails, it may cause the refrigerator to start abnormally or repeatedly.

5. Door sealing problem: the door is not tightly sealed or the sealing strip is aging, the internal temperature of the refrigerator is unstable, and the refrigerator is frequently started.

If you encounter the problem of repeated startup of the refrigerator, you should find the problem in time and solve it as soon as possible. You can try to clean the condenser, replace the thermostat or the door sealing strip, or contact the maintenance personnel for inspection and maintenance.
