The electric fan has not been used for a long time, and it will not move when it comes back for the New Year, what is the general reason? Which big brother knows?

If you don't rotate, it may be a problem with the circuit, and if you have no experience in circuit operation, it is recommended not to move it to prevent electric shock.

There are the following reasons:

1.If the starting capacitor is broken, if there is no other problem, the blade will turn when it is dialed, and the capacitor can be replaced if it is broken.

2.If the bearing is stuck, the bearing should be cleaned and lubricated.

3.The motor coil is broken in one phase, and there is also one phase energized, so there is the sound of electric current and cannot be rotated, so the motor must be repaired or replaced with a new motor.

Most of the electric fan motors use bearings.

motors, while bearing motors need to be oiled regularly to keep the linoleum inside.

The pads are always filled with oil to lubricate the shingle. If it is used for a long time without oil, the shaft and the pad will be held due to lack of oil, which will increase the starting resistance and cause the motor to fail.

Electric fan motors require capacitors to start, and capacitors may decrease or fail during long-term operation, resulting in difficulty in starting and inoperating.

First, it is not properly preserved, resulting in more dust between the motor and the shaft, the shaft is hugged, or the line is damp, and there is a poor contact with the line corrosion. First, the starting capacitor of the motor is damaged, you can first turn the fan blades clockwise, and then turn on the power switch immediately, and if it can turn, the capacitor is damaged.

The main problem may be that you accidentally bumped the wire pack when you pulled out the rotor - the wire was broken.

It's normal for the pen to shine, no problem.

Carefully check whether the wire is broken, if so, carefully pick the two ends of the broken end, scrape off the enamel, connect it with copper wire of the same specification, and use it after lacquering and insulation.

If multiple strands are broken, I'm afraid it's not easy to do, and it will cost more than 20 yuan to replace a motor.

The bearings are flexible. If you break the secondary winding resistance of the fan, you will know it by measuring it with a multimeter. Only a new one.

Whether your fan has been disassembled, if so, when reinstalling, the mallet should be struck back and forth on the side of the shaft to tighten the fixing screws diagonally to ensure that the shaft and the bearing are concentric and rotate flexibly. If you rotate the shaft by hand and rotate flexibly, it is estimated that the motor coil has a fault of inter-turn short circuit, and you must rewind the coil or replace the new motor to accompany the bridge family.

There is a slight short circuit inside the motor, and you can only rewind one, or buy a new one.

There is a suspicion that the starting coil is broken.

Open the back cover, look carefully, there must be a wire that is disconnected, find a soldering iron and solder it, it's OK.

There are the following possibilities: 1. Power supply problems, bad contact or disconnection somewhere; 2. The starting capacitance is bad (or the capacitance becomes smaller, and it is difficult to start); 3. The coil of the fan motor is burned; 4. The fan is stuck.

The starting capacitor is broken, let's replace it, a few dollars.

If the household electric fan does not turn, first check whether the power supply is normal, the power supply is normal, you can dial a fan blade is relatively easy, if it is very tight, you should continue to change the oil to clean it first, if it is very easy, you can turn on, turn on the fan, dial the fan blades (pay attention to safety), if you can turn, it is the fan starting capacitor is damaged or not connected well, and it can be a motor problem if it does not turn.

Fan selection. Commonly used electric fans include ceiling fans, floor fans, wall fans, Taimin stupid fans, and page fans, among which ceiling fans and wall fans are fixed installation, and floor fans, table fans, and page fans are easy to move and have a wide range of air supply. The output air volume of the electric fan is basically proportional to the diameter of the sash page, and different specifications of the fan can be selected according to the size of the room area.

What is your 100-square-meter room used for, and there are different options according to different uses.

I feel like you'd better install a few more ceiling fans, wall fans, or a few floor fans and page fans.

Recommend Huaben and Meiling fans.

After starting, use a wooden stick to dial the fan blades, if it can turn and the speed is normal, which should be the capacitor used to start inside is broken, remove it and buy a new installation according to the original capacity for a few dollars.

What should I do if the electric fan that has been used for a long time does not rotate? One trick to solve, using the right method is actually very simple.

It's just that the quality of the current fan is too poor, and we have a fan from the 90s, which turns on as soon as it is turned on, and it is okay to put it for a long time, and the wind is still very strong.
