The power cord is one of the most abused parts of a vacuum cleaner. With it being regularly wrapped around, swung around or even run over, it is not surprising if the power cord gets damaged very easily.
Movements done in the actual use of a vacuum cleaner tend to put strain on these cords which lead to its failure eventually. If vacuum power cords are left in their damaged condition, they become very dangerous and are just waiting to cause a fire hazard. So, commonly, a vacuum owner needs to know how to replace a vacuum power cord.
You can easily replace a damaged or broken vacuum power cord without the help of a professional. Repairing vacuums or any other tools, for that matter, at home can help you save a lot of money.
Although it mostly depends on the model of the vacuum cleaner, repairing broken or damaged vacuum power cords might take about 10 to 30 minutes to complete. While each vacuum brand has a slightly different power cord, all cords are wired into the motor in the same basic method. So to replace the old power cord with the new one, you first need to remove it.
Removing the Old Power Cord
- Unplug the vacuum from the electric source if it is connected. You can place the vacuum on a work table to make working on it easier. Place an old towel on the table so you can put the vacuum’s parts as you remove them. Keep all the removed parts in order so you can find them easily during reassembling.
- Uncover the brush roller on the bottom of the vacuum. Find the screws that are holding the housing that holds the roller in position and remove them. Detach the belt of the brush and pull the brush out. Unbolt the screws that hold the filter in position behind the brush assembly.
- Remove the screws that are holding the motor housing. On some models, you may have to release the handles for the housing to come off the vacuum. Take note of the wiring’s orientation on the motor. A white wire from the power cord should be attached with a white wire on the motor. A couple of colored wires should connect on the other wire.
- (Before you remove any cords or wires, be sure to carefully note how they are attached to the motor. This would help you draw a simple diagram of the wire arrangement, which would help you make sure the replaced wires are installed properly. Wires also come in different styles so it is very important to pay attention and check that they are the same with the new wires.)
- You will find wire nuts holding the wires of the motor and cord jointly. Twist the wire nuts counterclockwise to release the nuts. Take the wires apart. If the white wire has a terminal connection that fits into the motor, pinch the fastener jointly with a couple of needle nose pliers and pull out the terminal connection straight of the motor of the vacuum. To pull the wire free, separate the prongs of the terminal using a knife.
- Measure the space between the strain release and the end of the cord. Release the screws holding the strain relief of the cord and cord retainer to the body of the vacuum. These two function jointly to keep you from accidentally pulling out the cord of the motor as you operate the vacuum. Pull off the old cord of the vacuum and pull the strain relief as well as the cord retainer from the cord as well.
Attaching the New Cord
- Slide the strain relief and cord retainer onto the end of the new power cord. Put them in the same position as the old power cord. Measure to make sure you have the same extent of cord between the strain relief and the motor. At this time, do not fasten them in place.
- Strip 1/2 inch of wire casing and insulation from both the white and black wire on the new power cord with a sharp knife. Do not accidentally cut the wires.
- Slide back the white wires on the cord into the terminal. Crimp the terminal closed with a couple of needle-nose pliers. Push back the terminal into the motor. Alternatively, if the motor connects the white wires with wire nuts, join them.
- Twist the ends of the colored wires from the cord and motor together. Twist a wire nut that you detached earlier clockwise over their ends to secure them together.
- Attach the cord retainer and strain relief device to the body of the vacuum with screws. Make sure to keep the new cord in the same position as the old cord.
- Put back the handles into the vacuum. Fasten the motor housing. Slide back the filter into position and reattach it. Slide back the belt into the position and reattach it to the brush. Put back the housing over the brush and lock its screw into place.
If your vacuum’s cord wiring has soldering to hold the wires together, it would be best to hire a professional to replace the cord. But if you have good knowledge of how to solder, you can make the repairs yourself.
Take photos of “what is where” with your cell phone or digital camera as you disassemble the vacuum and expose the wiring. These photos will be helpful to reassemble the vacuum properly.
Get a replacement cord that is long enough for your vacuum to reach an entire room without switching outlets.When you separate the brush assembly, it is a good time to replace the belt if it shows signs of wear, such as evidence of stretching or cracks.
