What should we do if the air suspension blower blades don't move? Today, Shengyuan Technology will give you a brief analysis: this fault is common in capacitor start air suspension blowers. The main reasons for this malfunction are: the capacitor has no capacity or severe leakage, or the starting winding is damaged. Remove the original capacitor and try connecting it with a good one. If the blower operates normally after replacing with a new capacitor, it indicates that the fault is indeed caused by capacitor damage. If the air suspension blower still does not function properly after replacing the capacitor, it is mostly caused by damage to the internal starting coil of the air suspension blower. Only by replacing the coil can the fault be eliminated.
When the air suspension blower does not rotate and makes a buzzing sound, the main reason for this fault is that the fan has been used for a long time, and too much dust has accumulated, resulting in a high friction coefficient between the rotor and the bearing. The rotor is blocked or even stuck, causing the coil to overheat and be damaged. The above phenomenon can be identified using the following methods: turn on the power, press the blower housing with your hand, and if there is a slight vibration sensation, it indicates that the coil should not be faulty, because the rotor is stuck. After the power is cut off, open the back cover of the fan and add a few drops of lubricating oil to the shaft sleeves at both ends of the rotor. While dripping, move the blades until they are flexible, and the blower fault can be eliminated. If there is no message when pressing the fan by hand, it may be due to a lack of 220V AC input or a damaged coil. In this case, the power supply should be cut off, and the two leads of the fan should be disconnected from the two contact points of the power line, allowing it to hang in the air. Connect the power supply and carefully measure the two ends of the power cord with an electric pen. If one end lights up and the other end does not, it indicates that the power supply incoming line is normal, which may be due to damage to the fan coil. If the electric pen measures that both ends light up or do not light up, it indicates that there is a problem with the power supply incoming line and replacement is needed.
