8 common problems when using electric fans and remedies

Fans when used for a long time may have some minor incidents that suddenly affect your life. We would like to share with you some common problems when using them and how to fix them quickly.

1. The fan does not run when the power button is turned on

One day you press the power button on but do not see the fan working. The cause of this problem may be due to a malfunctioning power supply, an overloaded motor or a control valve. To fix this problem, you should first check the power supply, fuse, and control valve if it is properly opened or closed. Also, can check the voltage to see if it is suitable. After determining the exact cause can be overcome on the spot or taken to repair outside.

2. The speed switch or button switches

Inactive buttons may be due to poor electrical reception.

Long-lived buttons or switches are bottled and may be damaged so they cannot be clicked or rotated. The reason is that much friction in the process of use makes the metal part of the electrical relay worn, or long time rusted and dirty so it is difficult to power.

To fix the problem, use the WD40 lubricating oil bottle to spray into the grooves of the keys, buttons to clean copper rust and remove dirt, then push the buttons repeatedly until it is okay. If it is due to the metal where the relay is worn, only the new button can be replaced.

3. The navigation function is broken

Fan function is easy to break.

The functions are mainly used in plastic so when used for a long time and using too much force, it is easy to slip or break. For this case, the only way is to check the greases on the inner gears and then buy the newly installed plastic case. If not, you can always replace the utility kit. Contact the store for genuine purchases.

4. The propeller falls

The worn shaft causes the propeller to fall.

The impeller enters the fan motor with a spiral spindle. If used for a long time, friction on the rotating rotor can cause the shaft to be worn so that the rotor cannot be held when the rotation force is too large causing the wing to fall off the shaft.

This problem can only be solved completely by replacing the reel. However, this job requires skill, you should bring out to a professional shop outside to repair.

5. Loud noise

If the fan is too loud, the cause may be due to friction between the rotating shaft and the brass of the machine causing the noise. To fix the problem, remove the motor and check the lubricating oil and then try again.

6. The fan is hot

The fan motor is hot if the maximum capacity is used regularly.

This is a fairly common case, probably due to the use of a fan at maximum speed for a long time or because the fan motor is dry causing friction when turning too large, causing a thermal effect. .

To make the fan less hot, it should be noted that fans should not be used at full speed for a long time. Remove the fan motor and use lubricating oil for the engine.

7. The fan is shaking

The fan is too high to be easily shaken.

Standing fans that are too high suspended fans can be shaken after a period of use. The main reason is due to screw fasteners, loose joints or fans adjusted at a height not suitable.

This error is easily solved by checking and screwing the screws or joints tightly, should not adjust the fan too high or run at maximum speed.

8. Slow rotation fan

Regularly lubricate the fan motor regularly.

Slow fans may be caused by dust, oil drying, damage to bearings or changing resistors, causing the capacitor to fail. First try to use the hand to rotate the propeller to see if it is stuck, if it is trapped, clean the screw again, check the bearings to check the oil or replace the new ball if it is damaged. If it is still slow, try using a resistive measuring device to test the resistance of the ear plug and motor, if the difference is too large, replace the new capacitor.
