The ceiling fan motor has only two interfaces at one end. I connected two wires and they came out; Connect these two wires directly to the socket to see if the ceiling fan rotates? If you don't want to switch, go to the merchant to replace it. Only when you can switch it normally can you connect the speed controller. Connect the red and black wires of the speed controller to 220V mains power, and don't forget to lap the two capacitor wires separately on the green and black wires! If you want to

Install a speed controller, just connect it in series with the electric fan in the mains, and the wiring method of the electric fan remains the same. Use a multimeter to measure the resistance between two wires. If the resistance of two wires is measured to be high, then the third wire is the common wire end. When wiring, the common wire is directly connected to a live wire. Based on the common line, measure the other two wires separately. The one with high resistance is the main winding coil, and the one with low resistance is the auxiliary winding coil. When wiring, the neutral wire of the power supply is connected to the terminal of the main winding and one end of the capacitor, while the other end of the capacitor is connected to the terminal of the attached winding. If the fan has a reverse situation, you can swap the two ends of the attached winding coil. After swapping, the fan forward speed controller will not turn on. Use an electric pen to measure that both wires on the motor terminal are live wires, which are controlled by your fan switch.
