Replacing a ceiling fan is easy when a fan was previously used in the spot. The installation kit included with the new fan usually features mounting brackets. If these are not provided, they can be bought separately at the store where the fan was purchased. With existing electrical wiring, only a basic knowledge of wiring and some basic skills are needed to replace the fan with a new one.
You will need:
Step 1: Turn off the circuit breaker to the room where the new fan will be installed. Verify that the circuit is off by flipping the wall switch on and then off.
Step 2: Remove the mounting bolts from the existing fan, holding the unit securely in the process. Disconnect all electrical wires, retaining the wire nuts for reuse. There are usually only one black and one white wire. A third bare copper or green wire may serve as the ground wire.
Step 3: Verify that the electrical box within the ceiling is secure. It should be mounted to a ceiling rafter or beam and should not move when grasped. A secure box provides a strong mounting surface for the new ceiling fan.
Step 4: Attach the new mounting bracket to the exterior of the existing electric box. Follow the manufacturer specification for installation and use the screwdriver to install the screws. Some manufacturers recommended that the screws be left loose, so verify this before screwing them into the box.
Step 5: Place the fan on the mounting hook located on the bracket. This will keep the fan steady during the wiring process. Wind the ground wire around the ground wire screw and attach the wires by color, following the manufacturer instructions. Use the wire nuts from Step 2 to cover the wire connections. Push all the wiring into the electrical box.
Step 6: Use the screws included with the fan to attach the fan motor to the mounting bracket. Flip the circuit breaker on and turn the power on to the fan to ensure the wiring was done properly.
