Analysis of the reasons why the range hood motor does not rotate

I have organized an online analysis of the reasons why the range hood motor (range hood motor) does not rotate, hoping to be helpful to you

       1. The thermal protection device or fuse device is burned out. If the thermal protection device or fuse device is burned out and has already been burned out, it is necessary to replace the thermal protection device or fuse device again
        2. The problem of poor contact or disconnected wiring between the power plug and socket is easy to solve. We can check the power indicator light to see if it lights up stably. If it turns off later and turns on later, it indicates that the circuit is connected
        3. Poor contact. Loose screws in the motor connector, poor wire contact, or loose motor terminals can be inspected by disassembling the machine
        4. The deformation of the moving contact of the keyboard switch causes the moving and stationary contacts to be indistinguishable. Wash the dynamic contact pad with a cleaning agent, and then use pointed pliers to clamp the root of the dynamic contact pad for correction, restoring elasticity and ensuring normal contact between the dynamic and static contacts
        5. If the fan blade is malfunctioning, please check the blade. If the blade is deformed and adheres to the bow plate, the gap between the blade and the bow plate should be adjusted, or the blade should be replaced
        6. Due to the wear and tear of the motor bearings, the stator and rotor of the motor collide, resulting in jamming. At this time, it is necessary to replace the bearings
        7. The motor starting capacitor is damaged. Please check if the motor starting capacitor is damaged. If it is damaged, it is necessary to replace the motor starting capacitor
        8. Manually rotate it a few times, and if the fan of the motor will turn on its own or lacks power, it means that the motor is lacking lubricating oil after prolonged use
