Why is the fan blade not spinning?

The reasons why the fan blades do not rotate are:

1. Poor maintenance and long-term lack of lubricating oil. Make sure there is lubricating oil on the fan shaft, otherwise the motor with the blades on it will not be able to move it. If you are at home, you can choose to turn off the power and then spin the fan blades. If the rotation is stiff, there is almost no lubricant.

2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will wear out, and the motor bushing will burn easily after wear.

3. Fan does not spin due to overheating. There is a motor in the fan and there will be an overheat breaker in the motor. If a short circuit occurs in the coil winding, the heat will increase in a short time and the motor will stop in this case.

4. The capacity of the starting capacitor becomes smaller. When the fan is used for a long time, the capacitive capacity decreases, resulting in a decrease in the motor starting torque and the inability to drive the load.

5. Electrical outage issues, such as line damage, etc.

Interview methods:

1. Just add a little oil to the engine (if you really can't find lubricating oil, using vegetable oil at home can also be used).

2. Replace the capacitor in the fan. We can see the capacitor after removing the motor housing behind the fan. We can replace the capacitor with the same specification, or the capacitor can be larger than the original one (no more than 20% of the original capacity).

3. If the fan blades do not rotate due to wear, replace ifjust the ring.

The electric fan may not rotate at low speed for the following reasons:

1.

Power supply problem: First check if the electric fan works properly. connected to the power supply and the plug is not loose. If the power cord is securely connected, you can try plugging the electric fan's plug into another outlet to test if it is caused by a power outage.

2. Fan Switch Problem: Failure to spin at low speed can also be caused by a malfunctioning fan switch. You can try moving the switch to other speeds. If the fan operates normally on other speeds, the low level switch may be damaged. At this point, you can replace the fan switch portion or the entire switch to resolve the issue.

3. ProblemMotor Me: The fan motor may also malfunction, preventing the fan from spinning at low speed. A damaged motor often results in erratic current flow or an inability to deliver sufficient power. In this case, you will need to replace the fan motor component.

4. Fan blade problem: Check if the fan blades are blocked or covered in dust. Dust or blockage can affect the rotation of the fan and prevent it from working properly. You can use a soft brush or vacuum cleaner to clean the fan blades and the area around the fan to make sure they are not clogged.

5.

Other faults: If the fan still cannot operate normally after eliminating the above possible causes, there may be other faults, such as circuit board damage, poor line contact, etc. . In CIn this case, it is recommended to send the fan for repair or have a professional inspect it.

In summary, the reason why the fan is not spinning at low speed could be due to power supply issues, fan switch issues, motor issues, fan blade issues, fan or other faults. Depending on the situation, you can eliminate these possibilities one by one to find and resolve the problem.
