What are the reasons for the radiator fan of the Sylphy not spinning?

[DiStella]

The reasons for the radiator fan of the Sylphy not spinning include poor motor lubrication, a small starting capacitor capacity, and prolonged motor usage. Below are the detailed explanations: 1. Poor motor lubrication: Poor motor lubrication can cause the fan not to spin because the motor lacks sufficient lubrication, preventing it from driving the fan after installation. Adding lubricating oil can resolve this issue. 2. Reduced starting capacitor capacity: If the starting capacitor's capacity decreases, the motor's starting torque will also decrease, making it unable to handle the load. Replacing the starting capacitor can fix this problem. 3. Prolonged fan usage: Extended use of the fan can lead to motor wear, especially if the motor's bushings wear out, which may cause the motor to burn out. This also increases the motor's internal resistance, reducing its load-bearing capacity and preventing it from driving the fan blades. Replacing the motor is the solution in this case.
