1. The first step is to go to the hardware store to buy butter and other lubricants. But a $5 packet of butter is really only a small amount of money. If you know someone who owns or has a car repaired, this is a good idea.
2. First remove the fan cover and set it aside, push the fan blade to the right to loosen it, then remove the fan blade, then remove it.
3. After removing the fan blade, remove the white tool in the photo, turn it to the left by hand to loosen it, then remove it and store it with the back cover down.
4. Use a Phillips screwdriver to remove the transmission knob, then turn it counterclockwise to loosen it. Remember to press lightly to avoid damaging it. Then remove the screws and remove the engine cover as shown in Figure 3. The rear can be removed, but if you have difficulty, use pliers to remove it and then remove the front and back covers.
5. Turn back and unscrew the rotating cover. Make sure to remove the center rotary knob. Once the screws are removed, replace the cover and remove it, then remove the screws from the rotating cover.
6. Finally, remove the four motor screws, remove the motor cover, grab the front cover, then move the rear cover to remove it. Be careful not to damage the center spool and remove it slowly.
7. Grab the middle one and move it back and forth. Start by backing out the butter as shown in photo 2. You can add more butter to several spots, put it in place, put the spool back in, grease the back cover, then put the back cover back in and screw it back on. Don't forget to tighten it.
8. After installing the motor screws, open the fan andubrify it. Lubricate first from low speed to high speed. If not moved, the condenser will burn. Check the path by removing the button cover. You can remove and replace the condenser.
9. Install the rotary knob cover, put it back as shown in the picture, then tighten the three screws to fix it, then install the top screw.
10. Install the shield, push it in by hand, then install the four screws.
11. Then install and tighten the rear cover, install the fan blades, then turn to the left to tighten.
12. Install the front guard and tighten it, leaving a few screws. Be careful not to twist it too much. It doesn't turn because it doesn't turn. Before installing the back cover, make sure it is installed in the same location. Install the rear cover in the same location. On the slot, push it into place with your hands and tighten the screws to finish.
Reasons forthe reverse rotation of the electric fan 1. The electric fan has two windings: the main winding and the auxiliary winding. The main winding is used for running and the auxiliary winding is used for starting. When these two wires are connected backwards, the fan turns upside down. 2. The capacitor changes the size of the magnetic field, so that the difference between the main winding and the auxiliary winding is 180 degrees. Assume the main winding is 180 degrees ahead of the auxiliary winding and the fan is rotating forward. If the primary winding lags behind the auxiliary winding by 180 degrees, the fan starts rotating in reverse. 3. In addition to the reverse connection of the electric fan, the reverse connection of the electric fan may also be caused by improper installation of the blades or damage to the motor.de.Therefore, the reversing of the electric fan is not only caused by a single reason, but also by several reasons. How to turn the electric fan forward in reverse? 1. The electric fan is spinning backwards because the wires are not properly connected. When the power supply is connected to the common and run terminals, the fan rotates in the forward direction, and when the power supply is connected to the common and start terminals, the fan rotates in the reverse direction. If it is a three-phase fan, it can be restored to normal by changing the phase order of the power supply. 2. Reverse rotation of the electric fan may be caused by motor damage. In this case, the motor needs to be replaced and it is best to ask a professional to do it. If someone who does not know how to replace a motor rushes to replace the motor, the electric fan may be damaged.be damaged. 3. Reverse rotation of the electric fan may be caused by improper installation of the blades. At this time, you can check the instruction manual and reinstall the electric fan blades correctly according to the correct installation method, and the electric fan can rotate normally.
