In order to replace a ceiling fan capacitor, you will need to follow a few basic steps. First, make sure you have the correct type of replacement capacitor and know its exact location. Next, make certain that you have the power supply completely disconnected. Then disassemble the fan until you gain access to the ceiling fan capacitor. Finally, replace the faulty part, reassemble the fan, and turn on the power supply.
Before you can replace a ceiling fan capacitor, you must know what replacement part to use. It may be necessary to consult the fan manufacturer to obtain this information. Once you have the correct part, determine its exact location in the unit. In most cases, the capacitor is in a metal housing located between the light fixture and the fan motor. This housing typically contains the fan’s speed control mechanism as well.
It is important to disconnect the electrical current going to the fan before you begin working. The current should be turned off at the electrical circuit panel to be completely safe. If you do not know which circuit breaker or fuse is connected to the ceiling fan, turn the unit on and disconnect each circuit until the fan loses power. After disconnecting the electricity, wait several minutes for the ceiling fan capacitor to discharge any stored electricity before proceeding with the work.
Disassemble the light fixture and remove it from the fan. It is important to mark each wire that you disconnect in order to correctly reassemble the fan. Keep all screws and wiring hardware in a safe location for reassembly. Remove the screws securing the bottom plate of the metal housing. Locate the ceiling fan capacitor and cut the wires as close to the component as possible.
Use a wire stripping tool to remove a small amount of insulation from the wires. Attach the wires from the new ceiling fan capacitor to the old wires using a screw-on or crimp-type wire nut. It may be necessary to rearrange some of the wiring to make room for the new capacitor. Make sure that none of the wiring is caught between the bottom plate and the housing. Reattach the bottom plate of the metal housing.
Reconnect the wiring from the light fixture to the fan in the correct order. Reattach the light fixture to the fan and check that it is securely screwed in to the metal housing. Turn on the power supply to the unit. Check the ceiling fan and light fixture for proper function.
