Why is one car fan spinning while the other is not?

[DeCaleb]

Here are the specific reasons why one car fan is spinning while the other is not: 1. The water temperature has not reached the required level: The car radiator fan operates with electronic temperature control, so it generally only starts spinning normally when the internal water temperature reaches the specified level. If the temperature is too low, the radiator fan will not spin. 2. Long-term wear: Prolonged use of the fan can cause severe wear, as the motor will degrade. If the motor's bushing wears out, it can easily burn out. 3. Motor overheating: The fan assembly includes a motor, which has an overheating circuit breaker. If a short circuit occurs in the coil winding, the heat generation can increase rapidly in a short time, causing the motor to stop spinning.
