A 3-speed fan/blower motor switch is a device that allows you to control the speed of a fan or blower motor. It is typically a rotary switch with three positions: low, medium, and high. The switch works by connecting the motor to different power sources, depending on the selected speed.
They are used in a variety of applications, including:
- Ceiling fans
- Attic fans
- Range hoods
- Air conditioners
- Heat pumps
To replace a 3-speed fan/blower motor switch, you will need to disconnect the power to the fan or blower motor. Then, remove the old switch and connect the new switch to the same wires. Be sure to follow the instructions that come with the new switch.
