The cooling fan needs to be turned by hand every time it is started. Why is it necessary to replace the cooling fan? Suzhou Santian Precision Mould Co., Ltd. will answer your question!
If your cooling fan needs to fiddle with the fan blades every time it starts, it can start, then it may be because your cooling fan has been used for too long, the internal parts are aging, or the engine oil is rusted and stuck. May wish to find problems from the following aspects:
1. Capacitance
There is a starting capacitor inside the fan. After energizing, a momentary voltage is applied to the coil to start the fan. If the capacitor is damaged, it is easy to cause the fan to start slowly. Only one capacitor needs to be replaced.
2. The fan shaft is stuck
Open the back cover of the fan and check whether the fan shaft is stuck. If it is stuck, just apply oil to the shaft to solve the problem.
3. Long-term unused causes rust
Only need to disassemble the fan shell, then derust the internal parts of the fan, and finally lubricate it with engine oil.
4. The coil is damaged
If the above three conditions are not met, it may be that the coil is damaged, it is recommended to replace a cooling fan, because the price of the coil replacement is the same as the price of the fan.
