1. Observe whether the circulating fan in the room is working normally. If the burnout does not work, the evaporation cannot evaporate normally, so that it cannot be cooled.
2. Determine if there is voltage supply to the compressor. For example, is the AC contactor connected to the compressor unit sucked? Is the wire connecting the compressor not broken or not connected properly? And determine whether the voltage meets the rated voltage requirements of the compressor.
3. Determine the current of the compressor unit. The current must reach the rated current of the compressor. If the voltage is normal, the current does not meet the requirements, indicating the lack of refrigerant refrigerant.
4. If the high temperature box is a cascade unit, observe whether both units are running. If one unit is not working, it should be stopped immediately. Find out the cause of the compressor that is not working and analyze it.
5. Observe whether the cooling fan of the condenser is working at work, and the steering of the cooling fan is normal? When working normally, the wind should blow outwards.
6. Determine whether the high temperature tank compressor lacks refrigerant. Use a pressure gauge to observe whether the pressure after the compressor is started. Or feel the temperature of the compressor high pressure exhaust pipe by hand. When normal, the temperature should be very high and hot. In the case of dual-unit refrigeration, it is necessary to judge that the compressor lacks refrigerant. 
Regarding the reason why the high temperature box does not cool down, make the following judgment to find out the cause:
