The metal connections on the light switch may wear over time, or the one installed might be a defect and never had a properly made connection at all. Ask This Old House Master Electrician Heath Eastman demonstrates a variety of ways to troubleshoot and repair flickering lights. Excess voltage can be a safety hazard in your home and lead to an electrical emergency. That’s why it’s imperative to call an electrician to diagnose the problem immediately. Rather than try to inspect the circuit yourself, it’s always best to hire a professional electrician to do the job.

Loose, Outdated Wiring Connections

You now have a better understanding of some potential causes of the flickering in your LED lighting. Compared to older lamp types, LED bulbs typically operate much cooler, but if they do overheat, this could make them flicker. In many cases, turning the switch in the right direction will stop the flickering. A flicker typically starts when the brightness is reduced below 50%. To make sure it’s not just a loose bulb causing all of this trouble, give the LED bulb a little twist before continuing. Please note that even LED downlights (or “recessed lights”) can also loosen over time.

Top Tips for Adding Under-Cabinet Lighting in Your Kitchen

Needless to say, a flickering light bulb is not something that should be taken, well, lightly. Loose or outdated wiring is one of the leading causes of house fires. In any event, whether it’s a system-wide issue or confined to one location, these problems can quickly turn into a fire hazard. If your lights are flickering throughout your whole house, it can be due to the current weather conditions, such as high winds and storms that can impact power lines. Other reasons include loose service conductors in your central electrical panel, faulty connectors, worn down wiring, or improperly connected wiring.

If improperly installed or protected, some older types of light fixtures, especially recessed lighting, are more prone to overheating.

It’s also possible that the bulb is reaching the end of its natural lifespan and will need to be replaced anyway. Power surges commonly happen when lightning strikes near your home. Lighting can cause thousands of volts of electricity to surge through the grid that your home is on. Contact an electrician right away if you have a power surge so they can make sure that your home didn’t suffer serious damage. Electric wiring lasts for an average of 60 years, but it can go bad in years or sooner. You can find out whether or not you should replace your electrical wiring if you hire an electrician to inspect your home.

How To: Replace a Light Switch

Save yourself the additional hassle by checking the information with your light fixture to see which gauge wire you need. Some types of bulbs aren’t meant to work with all kinds of switches which can cause your lights to flicker. For example, a dimmer switch won’t work as intended if you have a bulb that isn’t meant to be dimmed. Lights can flicker due to everything from old wiring and strong winds to faulty switches. That’s not always the case, however, because flickering lights can sometimes indicate a larger electrical problem.

Downlight & Dimmer Compatibility

It could also be an issue with the electrical service, not necessarily your house wiring. For example, the power from the grid could be fluctuating, or a neighbor on the same transformer could be drawing a large amount of power. If someone down the street is engaging in heavy electrical use, it can cause your lights to flicker. If this isn’t the case or if the lights are also flickering at their house, the issue might lie with your utility service. An electrician can determine if it’s time to call them for a repair.

If multiple lights are flickering in only one area of your home, you're likely experiencing a circuit issue. It could be a loose connection in just that circuit, or the circuit might be overloaded. While LED bulbs will get dimmer as they burn out, lights flickering typically doesn’t indicate that they need to be replaced.

If you're trying to pinpoint which appliance is causing flickering, start by powering each load on at the circuit breaker. Buzzing could also occur in this instance, so listen to each circuit as it is powered on. Turn off the power to any switch or fixture at the circuit breaker before beginning any electrical work.

Avoiding attending to wiring and connection issues can also lead to electrical shock and negatively impact certain safety features like breakers. A professional electrician can look at your wiring and let you know if there are any issues. They can also let you know if there are things you can do to reduce the likelihood of dealing with flickering lights in the future. If you’ve tried troubleshooting the problem and you’re still dealing with a light that flickers, you may want to have a professional electrician take a look at your home’s wiring. The licensed electricians at Dean’s Home Services are experienced with troubleshooting electrical issues in the Twin Cities. Your light fixtures may be causing your lights to flicker, especially if you have an older home.

You may not need to look further than your neighbor’s house if you notice your lights flickering for no apparent reason. This is often the case if your lights flicker during the day when there is no inclement weather or power surge. If all the lights in your house are flickering, it could be due to a variety of reasons. The most likely causes are either a poor electrical main connection, old wires, a utility issue, or voltage fluctuations.

The answer is one, but that one person needs to screw it in correctly to keep it from flickering. The solution could be as simple as twisting the bulb so it sits tightly enough in the socket to make a connection. They won’t interfere with other devices’ ability to receive electricity, such as your LED bulbs, if they do it in this way. Specific high wattage load incandescent bulbs are supported by dimmers for conventional lighting. They function by uniformly varying the amount of current flowing into the bulbs.

You should never deal with electrical wires without the proper training. Instead, we recommend contacting an electrician who can perform an electrical inspection to check for areas of concern and address them. With this contact surface, no electrical current can run through unless the circuit has been closed. Energizing it and switching it on closes contact and enables the current to flow. Some examples of normally open circuits are equipment cooling systems, pilot lights, and lighting occupancy sensors. When you’re trying to relax at home or get ready for the day, flickering lights are probably the last thing you want to deal with.

In many cases, they’re a telltale sign of a much more serious electrical issue that requires immediate professional attention. The sparks created by arcing can exceed 10,000 degrees Fahrenheit, creating a major fire hazard. If you suspect that damaged wiring is the culprit, cut off power to that wire by switching off the corresponding circuit breaker on your breaker box. Then pick up the phone and call a licensed electrician to assess and repair the problem. Lights flickering in one room could indicate a problem with the wiring.

Contact a professional electrician if your lights keep flickering after you try several solutions. Sometimes, flickering lights are a sign that you have a serious electrical problem, so you don’t want to waste any time. When LED lights flicker, it is usually a different problem that doesn’t have anything to do with your electrical system. Instead, it has something to do with your dimmer switch on your lamps or lighting fixtures.
