As a homeowner, I often overlook electrical issues until they become serious problems. However, being proactive and addressing minor electrical repairs can prevent larger headaches down the road. Here are 7 underrated electrical repairs that every homeowner should learn how to do.
1. Replace Light Switches
Over time, light switches can become loose, corroded, or completely stop working. Replacing a faulty light switch is an easy DIY repair that takes just a few minutes.
To replace a light switch:
- Turn off the power at the circuit breaker and use a voltage tester to confirm it's off.
- Unscrew and remove the faceplate covering the switch.
- Unscrew the mounting screws holding the switch in place and remove it.
- Disconnect the wires from the old switch and connect them to the new one in the same configuration. Make sure the connections are tight.
- Screw the new light switch into the electrical box and replace the faceplate.
- Turn the power back on and test that the new switch works.
Having a variety of replacement light switches on hand means you can swap them out whenever one goes bad. It's a quick fix that keeps your lights working properly.
2. Replace Outlets
Faulty electrical outlets should be replaced right away. Loose, damaged, or nonfunctioning outlets can present a serious shock or fire hazard.
Replacing an outlet is very similar to swapping out a light switch:
- Turn off the circuit at the breaker box and verify it's dead.
- Unscrew the faceplate and remove it.
- Disconnect the wires from the old outlet and detach it from the box.
- Connect the wires to the new outlet matching the old setup.
- Secure the new outlet in the electrical box and screw the faceplate back on.
- Turn the circuit back on and test the outlet.
Having spare outlets on hand lets you quickly replace damaged ones. I recommend upgrading to tamper-resistant outlets for safety.
3. Fix Loose Electrical Connections
Vibrations from slamming doors or heavy appliances can cause electrical connections to become loose over time. Loose connections generate heat that could start a fire, so it's important to periodically check for any loose wiring.
To inspect connections:
- Turn off the power at the breaker box.
- Remove the cover plate and unscrew any outlets/switches.
- Look for any charred or warm wires, which may indicate loose connections.
- Check that all wire connections are tight and secure. Tighten any loose screws or push-in connectors.
- Replace any damaged electrical wiring you find.
- Screw all the outlets and switches back in place and turn the power back on.
Doing periodic inspections for loose connections can prevent more serious electrical hazards from developing.
4. Install GFCI Outlets
GFCI (ground fault circuit interrupter) outlets are essential in bathrooms, kitchens, garages, and other areas where water exposure is likely. If a GFCI outlet detects any abnormal current flow, it will instantly shut off power to prevent shocks.
Installing a GFCI outlet is straightforward:
- Turn off power to the outlet at the breaker box.
- Disconnect and remove the old, non-GFCI outlet.
- Connect the wires to the LINE terminals on the GFCI outlet.
- Attach the outlet to the electrical box and screw it into place.
- Flip the reset button on the GFCI and turn the power back on to test it.
Having GFCI protection greatly reduces the risk of electrocution around water. I recommend upgrading all outlets located near plumbing fixtures.
5. Replace Extension Cords
Extension cords take a lot of abuse and can become damaged over time. Fraying, cracked insulation and loose plug connections are warning signs that an extension cord is unsafe.
Rather than continuing to use damaged extension cords, it's best to replace them. When shopping for new extension cords, look for:
- Heavy duty and outdoor-rated cords for durability.
- GFCI protection for added safety.
- Proper wire gauge for the amperage rating.
- ETL/UL listing to verify safety testing.
Replacing worn out extension cords prevents electrocution and fire hazards. I make it a habit to inspect and replace damaged cords.
6. Install Electrical Labels
Having a properly labeled electrical panel makes it much easier to shut off the right circuit in an emergency. But many homes lack a clear labeling system.
It's simple and inexpensive to install circuit labels:
- Shut off a circuit breaker and see which outlets/lights it controls.
- Write the details on a label, like "Kitchen outlets".
- Turn the breaker back on and repeat for each circuit.
- Place the completed labels on your electrical panel.
Taking the time to properly label each circuit lets you quickly locate the right one. I recommend using durable self-adhesive labels.
7. Clean Electrical Panels
Electrical panels inevitably collect dust, cobwebs, and other debris. Excess dirt buildup can lead to overheating and safety issues.
Here are some tips for properly cleaning an electrical panel:
- Turn off the main breaker and all circuits.
- Remove the panel door and outer cover.
- Carefully vacuum out any dirt or dust.
- Clean the interior with a brush and compressed air.
- Wipe down surfaces with a dry cloth. Avoid harsh cleaners.
- Inspect wires and components for damage. Replace anything that looks worn.
- Confirm all connections are tight. Tighten any loose screws.
- Replace the cover and door when finished.
Keeping your electrical panel clean improves ventilation and helps prevent problems. I like to clean mine annually.
Conclusion
While less glamorous than larger upgrades, addressing minor electrical issues promptly guarantees your safety. Learning basic electrical repairs will make you a more self-reliant homeowner. Implement these tips to keep your electrical system running smoothly for years to come. Let me know if you have any other underrated electrical fixes I should add!
