How to Repair USB Fans?
A USB fan will offer you better convenience by allowing you to power it with any USB device. It comes in a portable design and offers you maximum comfort. Many a time, your USB fan may not function appropriately. When you repair the USB fan, it can restore the original power. This will make sure there will be quiet operation, and you don’t have to get new parts. However, you will require some tools including a socket or wrench of 8 mm, medium to low viscosity lubricant, and a head screwdriver.
Understanding The Parts of USB Fan
You should know the different parts of a USB fan before you start the repair. On the side, it comes with a micro USB port that allows you to charge it. If you turn on the back, there is a battery compartment that has a plastic cover. There are also four screws that can hold the structure together securely. At the same time, the front has some buttons for turning on the fan and adjusting speed.
Removing The Fan Blade
The first thing you will have to do is to remove the fan blade. Loosen the screws with a screwdriver and pull it up. You don’t have to remove the screws fully as the blade will slide free. On the back of the mounting plate, you will find two more screws. Do not do anything with the screws for now.
Removing The Battery Compartment
The next step you will have to do will be to remove the four screws. However, make sure that you have not plugged it in. You can do it with the help of a screwdriver. Once you are done with it, you will have to unsecure the plastic fan cage. If it has a battery, you need to remove it from the battery compartment. Follow it by removing the wiring cover which is above the fan motor.
Checking The Inside
When you check the inside, you will be finding a DC motor that is glued to the fan’s wings. However, you can disconnect the PCB from the rest of the front structure. Keep in mind that the PCB is soldered with two metal latches.
Removing the Final Two Screws
Now carefully remove the final two screws that hold the mounting plate to the cage. Gently pass the motor at the back of the cage to the opening. Using a screwdriver and a wrench of 8mm, you need to remove the magnet mount from the motor’s body.
Inspecting the Motor
Once you are done sliding out the magnet, you need to inspect the motor as well as the magnet. It is one of the reasons that can cause hang-up.
The Reassembling Part
The final step will be to reassemble the magnet mount. Make sure that you don’t over-tighten it as it may lead the motor to bind. Clean the magnet shaft as well as the brackets before you intend to do it. Now you can use a low or medium viscosity lubricant and lubricate the mounting bracket and magnet shaft.
