Vacuum cleaner power cords experience plenty of misuse from being continually swung during the vacuuming process to being folded around the vacuum once the cleaning process is complete. These movements subject the power cord to a lot of stress, which ultimately leads to breakdown. Areas prone to damage include the switch, plug and the cord's centre section. These three sections can be fixed with the help of a professional electrician.

To repair the switch:

1. First, the contractor unplugs the vacuum from its wall socket.
2. Using a screwdriver, the contractor loosens the bolts on the switch plate that typically secure the switch in place. Usually, the cord is held firmly in place using wire nuts fastened to the individual wires. These wire nuts are unscrewed and the cord is detached from the switch.
3. Upon the removal of the cord, a wire cutter is used to cut the cord where the damaged wires are. The damaged wires are discarded.
4. The wire is installed back via the access hole. Using a wire stripper, the contractor strips insulation of the respective wires. About of ½ inch of exposed wire is left showing.
5. Thereafter, the exposed wires are connected together with the switch wires while ensuring similar colour wires are joined together.
6. The cord is pushed into the switch plate and the switch is re-installed with the screws tightly screwed in.

To repair the plug:

1. First, the contractor unplugs the vacuum cleaner machine from its wall socket.
2. Using a wire cutter, the cord is cut just above the damaged plug. The old plug is detached and discarded.
3. A new plug is attached to replace the damaged one. After loosening its housing, the new plug is inserted onto the cord. The wires are stripped with ½ inch of exposed wire showing. The exposed wires are fastened to the plug's electrical terminals in the plug cover. Note that the white wires, black wires and grounding wires are attached to the silver terminal, gold terminal and the green terminal respectively.
4. Finally, the plug body is re-installed into its housing.

To repair damage in the cord's centre:

1. First, the electrical contractor removes the vacuum from its outlet.
2. Using a wire cutter, the cord is cut on either side of the centre damage
3. Next, the male and female plugs are detached.
4. Each section of the cord, in this case the male and female plug is isolated in different sides.
5. On each side, the wires are stripped to expose at least ½ inch of naked wire.
6. The stripped wires of both the male and female plug are attached to the electrical terminals in the plug housing. The black wires are attached to the gold terminal; the white wires are fastened to the silver terminal and the green, grounding wire is attached to the green terminal.
7. Both the male and female plug bodies are re-installed into their corresponding housings. Finally, the male plug section is plugged into the female plug section.
