What are the reasons for the Sagitar fan not working?
3 Answers
The reasons for the Sagitar fan not working are as follows: 1. Poor motor lubrication: The fan not working could be due to insufficient lubrication of the motor, preventing it from driving the fan blades after installation. 2. Motor overheating: Overheating of the motor can also reduce its load-bearing capacity and effective power, making it unable to drive the load. 3. Reduced starting capacitor capacity: The capacitor's capacity may decrease, leading to a smaller starting torque of the motor, which cannot drive the load. 4. Prolonged motor usage: If the fan has been used for a long time, the motor may wear out, and the worn shaft sleeve can easily cause the motor to burn out.
As a Sagitar owner, I once experienced the fan stopping during traffic congestion, causing a frightening surge in water temperature. After stopping the car, I first opened the engine hood to check the fan fuse. I located the corresponding labeled fuse in the fuse box and found it had blown, so I replaced it with a new one to test. If the fuse is fine, the next step is to test the relay. A temporary method can be used: swap relays of the same model to see if they work. If that doesn’t solve the issue, the fan motor might be damaged. If you touch the wires and feel no vibration or heat, it’s basically confirmed. From my daily driving experience, fan failures are often due to motor aging or wire corrosion, especially in humid areas where rust is common. If you notice any abnormalities, it’s best to pull over immediately and call for repairs to avoid engine overheating damage. Towing the car to a shop for inspection is also a hassle-free option. Regularly washing the car and cleaning the radiator fins can prevent dust buildup and extend the lifespan.
I believe the main reasons for the fan not moving include motor burnout, control module failure, or temperature sensor malfunction. First, confirm whether the fan should be running when the car is hot but isn't. If the coolant temperature gauge is normal but the fan remains still, it might be a motor issue; visually inspect the fan in the engine bay to see if it's stuck. Checking for a blown fuse is also straightforward—refer to the fuse box manual for the location diagram and replace it if necessary. If the relay shows no response, test the input voltage; if there's no power, replace it. Sensor errors can be diagnosed using an OBD scanner to read fault codes. It's recommended to have a multimeter on hand to measure the motor's resistance—an infinite reading indicates burnout. By systematically eliminating possibilities like this, you can pinpoint the root cause and save time. If unsure, consult a professional shop.
