| If the fan has 3 speeds, it should have a white, black, and red or other color of wire running to the switch. The switch should have 4 positions, connecting the black wire from the house to none, the black, the red, and both wires to the black wire from the house. Even if the switch isn't correct, you should be able to change connections with the power off, and try the other speeds. It is possible one of the windings in the motor is open and only one speed will work. If the fan only has 2 wires, it only has one speed. |
