Why Do Lights Flicker?
If the lights in your house are flickering, your electrical safety could be at risk. How do you know if the flickers are just a minor annoyance or a major electrical problem? When in doubt, always call a local electrician, and for your peace of mind, make sure they have electricians on call for emergencies too.
In this post, we’ll take a look at the reasons your lights might be blinking and how to know if it’s a big problem or a little one.
Overloaded Circuits
- Large appliances like sump pumps and washing machines can cause flickering when they turn on.
- This is normal and you can minimize it by plugging them into their own 240-volt outlets.
- If the flickering is severe or if it has been going on for a long time, your appliance may have a defective motor that causes it to “hot-start.” If that’s the case, you must call a professional electrician to fix it.
Outside Causes
- Storms can cause short-term flickering.
- So can your neighbors; if you share a transformer with them, their electrical use can cause blinking on your lights.
Light Bulb Types
- If a defective light bulb is a culprit, change it.
- A CFL bulb paired with a dimmer switch won’t work properly and the dimmer switch will make it blink.
- If all the flickering lights are controlled by the same dimmer switch, the dimmer switch is to blame.
- A faulty light fixture can also cause flickering.
Loose Wiring
- A loose or failing switch will cause anything plugged into it to flicker.
- Loose circuit connection is a dangerous situation that affects the whole house’s wiring and should be handled immediately by a professional electrician.
- If you notice arcing–which looks like tiny lightning bolts running out of a socket–you are at high risk of an electrical fire. You need to call an electrician immediately.
Electrical Safety
The third-leading cause of home fires
- While defective light bulbs and storm-related flickers are not emergencies, loose wiring and loose connections can be if they’re not addressed immediately.
- Electrical problems are the third-leading cause of home fires in this country, causing over 51,000 fires each year.
- Arcing faults are responsible for almost half of those fires.
