Ceiling fans are great feature in any home. It helps circulate cool air in the summer and disperse heat in the winter. But if you are current ceiling fans is not working properly or just looks old why not replace. It is easier than you think.
Before starting any electrical work, lift the circuit breaker at the electric box, I confirm that the power is off. With a screw driver remove the blades on the old ceiling fan and set them aside. Now remove any screws holding the canopy and pull it back to get at the wire. You may have a separate switch for the light and the fan or it maybe controlled from two different locations by a three way switch. It would be a good idea to make some notes before proceeding. Remove the wire knots and disconnect the wires. Unhook the down rod holding up the fan and remove the assembly. Now, unscrew any brackets used to connect the old fan through the ceiling. The moving weight of a typical ceiling fan is around 35 pounds so it needs to be properly supported.
If you are replacing an old fan, do not assume it was installed right the first time. Make sure your electrical box is securely mounted to a ceiling joist. If a ceiling joist is not easily accessible you need to use a brace box. This connects between two ceiling joists and will support the weight of most ceiling fans. Slip the brace through the ceiling hole and position it between the joists, the length you set on top of the dry wall at each end. Center the brace over the whole and rotate the shaft with an adjustable wrench until the teeth embed in the joist. Attach the new bolt assembly to the bracket. Center it over the hole with the bolts facing down. Punch out one of the openings in your electrical box and fit the wires from the ceiling through the hole. Push the box up unto the ceiling hole, slide in the U-bolts through the holes on the top. Screw knots unto the ends of each bolt and tighten it. Most ceiling fans keep in the option allowing them close to the ceiling. Unfortunately, this does a poor job at circulating air. As long as your ceilings are at least 8 feet high, use a down rod so that the fan blades are at least 10 inches from the ceiling.
Attach the mounting plate to the electric box. Flat side up with the spruce provided. A simple -- the down rod and canopy according to the manufacturer’s instructions. Run the wires through the down rod and tighten all the set screws. Now, carefully raise the entire assembly to the ceiling mounting plate and seethe the bulb into the socket. This will support the fan while you are making the wiring connections. Connect the copper wire to the green ground wires on the fan base and connect the white nitro wires.
For lighted ceiling fans, there will be a black wire for the fan motor and a blue one for the light. If you are using a single switch, connect them both to the black hot wire of the house, though use the chains to control the fan of the light separately. If you have more than one switch connect the black wire to one black lead and the blue to the other lead wire. Screw wire knots unto the ends of each connection and carefully push the wires up into the electrical box. Attach the canopy to the mounting plate and tighten the screws. Now attach the fan blades one by one to the assembly. Install the glass shades and the correct wattage bulbs for your particular unit. Now, turn the power back on and make sure your new ceiling fan is operating properly.
