What Are the Causes of Flickering Lights in Your Home?


Are your lights flickering? Nothing ruins a day like coming home and finding that the lights in your home won’t stay on. Instead, they struggle to keep a steady beam of light.

How did this occur, and can you fix it? Well, there are a few causes of flickering lights that may affect your home. Once you fix these underlying issues, the flickering lights can be fixed as well.

Let’s take a look at what these issues are!

Electrical Supply Interference


Interference occurs when electrical issues from external sources are introduced into your home’s electrical system, disrupting the consistent flow of power from your home’s electric panel. This could include power lines from other areas, radio signals, or even electric motors from other appliances in your home. This interference can cause the electrical current to surge, which can cause the lights and other electrical components to flicker on and off.

The effects can be particularly noticeable if the interference is more consistent, such as when there is a power outage in a nearby neighborhood or during bad weather. By installing surge protectors in your home and keeping electric cables secure, you can reduce or even prevent the likelihood of electrical supply interference.

Malfunctioning Bulbs and Fixtures

If a bulb is not screwed in enough, or if it is damaged, it can cause the lights to flicker. Fixtures such as switches and dimmers can also be at fault for flickering. Wearing out or defective components in the electrical system can cause lights to flicker.

If a fixture or bulb is faulty or old, it should be replaced as soon as possible. Taking care of these issues can help to save time and money in the future, as these problems can cause more serious issues. Regular maintenance and replacement of worn-out components is the key to preventing lights keep flickering and other electrical problems in your home.

Wiring Issues

Poorly wired electrical outlets, loose wires, and inadequate voltage are all typical causes of this issue. If your outlets and wiring are too old, they may be unable to handle the current load and, as a result, may not be able to distribute the electricity. Also, a loose wire can prevent the current from flowing to the light, thus causing it to flicker.

Voltage issues are also a common cause of flickering lights. If your home is experiencing low voltage, it can create a ripple choose throughout the wiring, leading to flickering lights and sometimes even short-circuiting.

Faulty Appliances

When appliances short out, the lights in the same room can flicker as a result. Faulty appliances or poor connections can also be to blame for these flickering lights. When a major appliance, such as a washer or dryer, is in use, it can pull energy from the power line and cause the lights to flicker as a result.

In more extreme cases, if appliances draw too much energy, they can cause outages and blackouts, leading to flickering lights. It’s important to have any potential electrical problems with appliances addressed right away with an electrician to protect against potential hazards and save energy.

Diagnosing the Source of Flickering Lights

Flickering lights in the home can range from being harmless to dangerous. If you are having these issues, you should call a professional electrician right away to decide the cause and for your home to be safe.

Ignoring the issue could lead to hazardous conditions and cause further damage. Don’t wait, call an electrician today!
