The Compressor Can Not Start Running Normally Cause

There are many reasons why the compressor cannot start running normally, which may be caused by the power supply, motor, etc.

1. Power failure: power failure, low voltage, phase loss

2. Electrical circuit failure: fuse, contactor wiring loose

3. Motor failure

4. High crankcase pressure

5. Energy at high load level

6. Refrigerant water temperature reaches the temperature controller set value or temperature controller failure

7. Pressure relay: set value too low, alarm not reset, malfunction.

8. Heat relay is not reset after action

9. Oil pressure is low and normal oil pressure cannot be established

10. Cold, salt water unit cooling water, refrigerant water break water flow relay alarm or water flow relay failure
