When Does the Car Air Conditioning Fan Turn On?
1 Answers
Whether the car's cooling fan starts to rotate depends on the coolant temperature and is not related to time. Below is relevant information about the air conditioning fan: 1. Generally, the fan automatically turns on at medium speed at 95°C and at high speed at 105°C. 2. When the coolant temperature reaches 95°C, the fan starts operating at approximately 1600 RPM. At 105°C, the fan speed increases to about 2400 RPM to enhance cooling efficiency. Below are precautions regarding the car air conditioning cooling fan: 1. The cooling fan is controlled by the engine coolant temperature. Sometimes, the cooling fan may still operate while the engine is running. 2. As the engine coolant temperature decreases, the fan automatically stops operating, which is a normal phenomenon. 3. When the air conditioning is turned on for cooling in summer, the fan will start. When the cabin temperature meets the required level, the air conditioning compressor stops working, and the fan also stops. Therefore, when the car is idling with the air conditioning on, the fan may turn on and off intermittently, which is normal. 4. Since the cooling fan is controlled by conditions such as the vehicle's coolant temperature, there is a possibility of sudden activation. Therefore, when opening the engine compartment to inspect the vehicle, ensure safety by not placing hands on the fan to avoid injury from the fan blades. Generally, there will be a warning label on or near the fan in most vehicles.
