Here's how to go about it:
- Start by turning off the circuit breaker to the fan.
- Next, remove the cover on the fan housing or the globe light so you can access the switch, and unscrew the nut on the outside of the switch that holds it on.
- Pull the switch out of the housing from the inside, leaving the wires attached.
Keeping this in view, why there are three blades in a fan?
When a ceiling fan is balanced properly it means that it takes much less power in order to rotate the blades. Thus, there are ceiling fans with 4 blades over there as they don't add excess cool air throughout the room, simply because it is needed.
How are fan blades measured?
Ceiling fans are measured by the full size of their blade span (also called blade sweep), which is the diameter of the circle that you see when the fan blades are in motion. Or, in other words, fan blade span reaches from the tip of one fan blade to the tip of the blade directly across.
What is a fan blade?
A fan consists of a rotating arrangement of vanes or blades which act on the air. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner.
