The reasons for the condenser fan not working include insufficient power supply voltage that does not meet the air conditioning startup voltage requirements, burnt-out fan capacitor, or open circuit in the fan coil. The condenser is a component of the air conditioning system that quickly transfers heat from the tubes to the surrounding air. In most cars, it is located in front of the radiator. It is a device that converts gas or vapor into liquid. Below are common faults causing the car condenser fan to stop working: 1. The system lacks refrigerant or the pressure is too high, preventing the compressor from starting. 2. Faulty defrost switch, causing the air conditioning to stop blowing air after a while and then resume after a pause. 3. Moisture in the refrigerant, leading to alternating cold and hot air without changes in airflow volume. 4. Poor condenser ventilation, preventing the compressor from operating normally, while the fan runs at high speed. 5. The air conditioning system has been inactive for a long time, causing the refrigeration oil to settle and gaseous refrigerant to corrode the pipelines, resulting in system leaks.
