Causes and inspection methods for cooling fan not rotating
2025-05-12 16:34:25

Any electrical equipment will have a heat source during use. As large as new energy, charging piles, energy storage, wind energy, cabinets and other equipment that have developed rapidly in recent years, as well as small as desktop computers, printers, robots, servers, security monitoring, etc., the heat generation during work is large and small. This requires the installation of a Cooling Fan to dissipate heat to ensure that the equipment can work normally. However, as the use time is extended, some failures such as cooling fans not rotating are inevitably caused. At this time, the faults and solutions are needed to ensure that the equipment does not rotate. The faults of the cooling fan not rotating can be checked according to the troubleshooting method.


1. Check the fault point of the cooling fan not rotating


1. Check the blockage: Use your hand to rotate the fan blade to see if the resistance increases due to the accumulation of dust. The fan cannot rotate.


2. Check the bearing: gently shake the fan blade with your hand to check if there are signs of loosening to determine whether the Fan bearing is damaged.


3. Check the line: Is the connection point or plug loose or fall off in the cooling fan line?


4. Test fan: If possible, use an external power supply with the same voltage as the fan to power the cooling fan separately to see if it can solve the fault (low current such as charger)


5. Equipment power supply: Check whether the equipment power supply is normal, whether the power supply voltage is within the rated voltage range of the cooling fan, and determine whether the voltage is too low to make the fan unable to rotate.


6. Equipment line: The cooling fan with speed regulation function needs to check whether the transmission of the speed regulation line model is normal.


7. Replace a new cooling fan for testing and observe whether the fan is operating normally


2. What will happen if the cooling fan does not transfer?

If the heat dissipation fan does not rotate, it means that the heat generated by the equipment cannot be discharged in time, which will affect the normal operation of the equipment. If there is no temperature alarm speed feedback to ordinary equipment, there is a risk of burning the equipment at any time. In addition, the increase in equipment temperature will affect the equipment's working efficiency and may cause irreversible components to damage.


Summary: The role of the cooling fan on the equipment is very important. The cooling fan does not rotate is nothing more than a device problem. External factors and the fault of the fan itself can be investigated based on these three aspects. With the trend of intelligence of more equipment, you can purchase cooling fan with speed feedback or speed feedback alarm function to effectively and promptly know the fan fault and deal with it.
