Electrical questions, answered by experts

A faulty light switch can be a serious fire hazard. Light switches with exposed wiring, loose connections, or other electrical problems can cause overheating or sparking in or behind the switch, igniting nearby flammable material. If you suspect your light switch is faulty, turn off power at the breaker and contact an electrician.

You should aim to replace your electrical outlets every 15 years, although some GFCI outlets can last as long as 25 years. On the other hand, outlets can go bad much earlier if:

  • The wiring is in poor condition.

  • Your circuit is overloaded.

  • There are loose plugs in the outlet. 

  • If the outlet wasn’t installed properly. 

  • If the outlet wasn’t grounded. 

If a light switch is off, it’s very unlikely to cause a fire. For a fire to start, the switch has to be on, activating an electrical current, and the wiring must be faulty. However, the malfunctioning light switch could cause an intermittent current to move across the electrical wire. This issue could become a fire hazard with another device connected to the wire. You should replace the bad light switch as soon as you notice it or call an electrician.

An electrician can handle wiring issues with the garage door opener, like faulty connections, circuit problems, or sensor malfunctions, but they’re not the right person to hire for mechanical repairs. Garage door specialists handle things like broken springs, tracks, and panels, while electricians step in if there’s an issue with power supply, motor function, or safety sensors that aren’t responding correctly.

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.
