Top Causes of Flickering Lights in Homes and Ways to Troubleshoot
1. Loose Light Bulbs
If the flicker is only happening to one light, you probably need to simply tighten the bulb. Turn off the light and wait until the bulb cools down before screwing it into the socket. Make sure it’s secure. If the flickering continues, the issue is linked to something else.
2. Defective Dimmer Switch
Lights paired with dimmer switches can flicker if the bulb is loose. Again, turn the light off and securely screw the bulb into the socket. Remember that not all bulbs are compatible with a dimmer switch. If the issue persists, you may need a bulb that is compatible with a dimmer switch.
3. Improper Bulb Type
There is no such thing as a universal light bulb. What works for one lamp might not work for another due to things like incorrect size and wattage. If your light is flickering, you may need to change your light bulb to one that is the correct size and wattage.
4. Loose Electrical Plug
A flickering light bulb might be caused by something as simple as a loose plug. Check the outlet that your light is plugged into and make sure the plug is firmly inserted into the socket. If the flickering light continues after fully inserting the plug, you could have a more complex electrical issue going on.
5. Voltage Fluctuations
Persistent flickering lights and faulty appliances in houses point toward a voltage problem. Voltage fluctuations are dangerous and can cause electrical fires. It’s important to call a professional electrician if you notice voltage problems.
6. Utility Supply Issues
An issue with your utility supply affects everything in your home, not just one appliance or light. A utility supply issue isn’t something you can fix by yourself; it also usually affects the homes of your neighbors as well as yours. Call your utility company if you suspect a utility supply issue. Also, consider a whole-home generator installation to help keep your lights on during a power outage.
7. Overloaded Circuit
An overloaded circuit may also cause flickering lights if you turn on an appliance, similar to voltage fluctuations. If this happens frequently, and for a prolonged period of time, call an electrician. An overloaded circuit is dangerous and can be a fire hazard. Get in touch with a licensed technician for an electrical panel repair.
8. Outdated Wires
Older homes are charming, but old wires are not. Old or loose wires are a safety hazard and can decrease your energy efficiency. Give your local electrician a call if you suspect old or loose wires. An electrical safety inspection is likely needed.
9. Arcing
Arcing means that a connection is jumping over two points that are disconnected. You might also hear buzzing and cracking accompanied by a burning smell. Contact an electrician if you hear or smell strange noises and odors—arcs are very hot and can cause electrical fires.
Frequently Asked Questions About Flickering Lights
What’s most frustrating about flickering lights in houses is that they can either be a simple fix or something more serious. Below is a collection of the most-asked questions we get about flickering lights.
How do you fix a flickering light?
Fixing a flickering light can be as simple as tightening or changing a bulb. However, issues like voltage fluctuations, utility problems, and overloaded circuits may be to blame. If a simple fix doesn’t solve your issue, contact a licensed electrician.
Should I worry if my lights are flickering?
It depends on where and how often your lights flicker. Identifying the frequency of the flickering can help you determine if the issue is caused by something as simple as a loose bulb or something as serious as arcing.
Why are all of my light fixtures flickering at once?
