The cold dryer tripped. What's the reason?

1. Unstable power supply or poor contact

2. The working environment of the air compressor is not well ventilated, resulting in the failure to discharge the heat in time

3. It does not match the exhaust volume of the air compressor and is overloaded

4. The environment of the machine room is poor, and the radiator is blocked by dust

5. The temperature of the operating environment is high, and relevant cooling measures are not taken

6.Maybe the instrument of the controller is out of order
