Sometimes the flickering simply means you need to replace the bulb, but it could also be a sign that your light switches are a fire hazard. To help you watch for the warning signs of faulty electrical wiring, Johnny Sharif, electrical expert at Frontdoor, shares exactly what you should be on the lookout for. The electrical expert shares that any heat and sounds coming from a light switch should raise concern, as should any change in the switch’s normal operation. If you notice any of the main warning signs that Sharif mentions, have your light switches inspected by a professional as soon as possible so they can assess the severity or the issue and help prevent a potential fire hazard. Top 5 Warning Signs to Watch For These are the main warning signs that your light switches are a fire hazard, according to Sharif. If you notice any of these signs in your home, he says it’s best to have the light switch inspected as soon as possible to prevent a potential fire hazard. Discoloration of the light switch Heat coming from the light switch or the surrounding area Unusual sounds such as crackling or buzzing Flickering Any change in the normal operation of the light switch How to Know When There’s a Problem With Electrical Wiring A flickering light bulb may be a sign that your light switch is a fire hazard, but the flickering may also just be the result of a faulty bulb. So how do you know the difference, and how can you tell if there’s a real problem with electrical wiring that can potentially cause a house fire? Sharif says the first thing you should do when you have a flickering light bulb is to replace it in order to rule out a simple bulb issue. If the flickering continues even after you have replaced the light bulb, he says the issue could be a result of faulty wiring. “Signs of faulty wiring may include black marks or charring by the switch, any heat coming from the area, a burning smell or even hearing sizzling or popping sounds coming from the switch,” Sharif says. He explains these issues can suggest loose connections or issues with the wiring and should immediately be addressed and brought to the attention of a professional in order to prevent a fire. What to Do When You Notice These Warning Signs Knowing the warning signs to look for is the first step to preventing a potential fire hazard. However, what should you do if you hear a crackling noise coming from a light switch or suddenly feel heat coming from the switch and the surrounding area? “If you notice any of these warning signs or anything unusual with your electrical system, it’s best to turn off power to the circuit as soon as you can and consult a professional to assess the severity of the issue,” Sharif says. Keep an Eye on Light Switches Light switches may seem like a small and insignificant part of a room, however just like everything else, they do wear out over time. What’s more, many light switches are used multiple times throughout the day and are a high-touch item. Clean them regularly to prevent dirt buildup and discoloration, and keep an eye on them for both safety and aesthetic purposes. Call in an electrical professional if you notice any of the warning signs Sharif mentions, and replace any chipped, scratched, or dirty light switches to maintain a clean and polished space. When replacing a light switch, make sure it matches the color and style of the other light switches and outlet plates in the room to ensure a cohesive look and prevent it from looking distracting. Aesthetically speaking, replacing light switches and outlet plates is a simple and inexpensive way to update a space.

    6 Reasons Your Lights Are Flickering, Plus Easy Fixes

    ByStan S.

While flickering lights can stem from a major electrical problem, it is more likely that the issue is related to the bulb or switch. However, it is essential to identify the cause of the flickering lights so you can rule out any serious electrical issues. Learn the most common causes of flickering lights and how to fix them, as well as when it’s advisable to call an electrician. 6 Potential Causes of Flickering Lights Before calling an electrician, try troubleshooting these potential causes of flickering lights. 1. Bulb Issues One of the most common causes of flickering lights is an issue with the bulb. Fortunately, bulb issues are also the easiest fix. Solution: If you suspect the light bulb is burning out, you can easily test your theory by replacing the light bulb. If the new one doesn’t flicker, you’ve likely solved the problem. 2. Switch Issues Light switches see a lot of use. While premium switches may last a lifetime, budget light switches are likely to fail over time. In this case, you might notice the lights flicker when you touch the switch. Solution: If you suspect the light switch is causing the flickering lights, replacing the switch should solve the problem. To do so, turn off the electricity and the circuit breaker box, remove the switch plate, and uninstall the light switch. Wire and install the new light switch exactly like the old one, reinstall the switch plate, and restore the power. 3. Fixture Issues Less commonly, the light fixture itself may be to blame. If there are loose connections or corrosion in the fixture, the lights may flicker. Solution: You can attempt to repair the fixture by fixing the connections or removing corrosion, especially if it’s a premium fixture. However, it may be more beneficial to replace cheaper light fixtures. 4. Incompatible Bulb or Dimmer Switch If you’ve ever shopped for light bulbs, you may have noticed language on the box referring to dimmer compatibility. This is because some types of bulbs and dimmer switches don’t play well together. If you install a light bulb that’s incompatible with the light switch, it will likely flicker as a result. Solution: To ensure your light bulb is compatible with your switch, check the bulb’s specifications before purchasing a replacement. If you’re having trouble finding a light bulb that won’t flicker due to dimmer incompatibility, your best bet is to try a traditional incandescent light bulb. However, they may be difficult to find in some areas due to government restrictions on energy usage. Even LED light bulbs that specify dimmer compatibility can sometimes flicker when tied to a dimmer switch. 5. Wiring Issues Sometimes, the fixture, the bulb, and the switch may all be in good, working condition, but the wiring is to blame for the flickering lights. The wires could be worn or damaged, but it’s more likely that they are loose, causing an intermittent connection, which results in a flicker. Solution: With the power turned off, inspect the wiring and all relevant connections, including those at the switch, circuit breaker, and light fixture. 6. Electrical Load Issues If you notice the lights flickering whenever other appliances turn on, such as a vacuum, dishwasher, blow dryer, or other power-hungry products, it’s likely because you’re running them on the same circuit as the lights, causing an excessive electrical load on the circuit. Whenever these devices turn on, they draw a large amount of power, which causes the current running to the lights to fade, resulting in flickering. Solution: If the circuit is overloaded, move the high-power appliance to a different circuit. For something like a blow dryer or vacuum, unplug it and plug it into a different outlet. Install a dedicated circuit for large, permanently installed appliances, such as dishwashers. When It’s Time to Call a Professional Electrician If none of these solutions resolve your flickering lights or if the lights are accompanied by buzzing sounds, burning smells, heat around the fixture or outlets, or frequently tripping breakers, contact a professional electrician immediately. You should also consider professional help if multiple lights in your house are flickering and the issue isn’t isolated to a single fixture or circuit. If you haven’t already, a professional will likely instruct you to cut the power at the breaker until the problem can be remedied.
