Common Faults and Solutions of Automobile Blower

Automobile blowers play a core role in maintaining a comfortable environment in the car, however, they may encounter a variety of faults during use. The following is an introduction to these faults and their corresponding solutions:

1. Blades do not rotate:

Cause: Dust accumulated over a long period of use causes increased friction between the rotor and the bearing, the rotor may get stuck, and then the coil is damaged due to overheating.

Solution: Turn on the power and gently press the automobile blower housing. If there is a slight movement, the coil may be intact, and the problem may be that the rotor is stuck. You can try to clean the internal dust or replace the bearing.

2. It does not work but makes a "buzzing" sound:

Cause: Common in capacitor-start blowers, which may be caused by capacitor loss of capacity, severe leakage or damage to the starting group.

Solution: Replace the capacitor. If the problem persists after replacing the capacitor, it may be that the starting coil is damaged and the entire coil needs to be replaced.

3. Abnormal noise:

Cause: It may be caused by automobile blower blades beating debris, fan bearing wear, debris entering the air duct, etc.

Solution: Remove foreign matter in the blower, replace the fan bearing or fan, and remove debris in the air duct.

4. Slow fan speed:

Reason: Long-term use without cleaning dust, resulting in obstruction of fan rotation.

Solution: Clean the dust and keep the automobile blower clean.

5. Foreign matter inside:

Solution: Remove the dust filter, find the automobile blower blades, turn on the blower switch, find the cause of the abnormal sound, and remove the debris.

6. Insurance damage: Check the automobile blower insurance and replace it in time if it is damaged.

By checking and handling these faults in time, the normal operation of the automobile blower can be effectively guaranteed, thereby maintaining a comfortable environment in the car.
