Common causes of flickering lights:
A faulty light bulb
If only one light is flickering in your home, try replacing the bulb with another one. If you have a fluorescent or CFL bulb on a dimmer switch, replace it with an LED. Most CFL’s do not work correctly on dimmers and may flicker as a result.
A large appliance turning on
Take note of when your home lights flicker. When a large appliance like an air conditioner, heat pump, washer or dryer turns on, it pulls a lot of electricity, which can temporarily take some of the electric current away from the rest of your home and cause your lights to flicker.
Too many outlets/lights on a circuit
In older Atlantic and Cape May County area homes, it is not uncommon for your home’s circuits to be overloaded with too many outlets, lights or appliances. Try unplugging some of your appliances from the wall and see if the problem goes away. A licensed electrician can check your breakers for overload and recommend any fixes in this situation.
If your homes lights are flickering and it doesn’t seem to be a result of a large home appliance turning on or an overloaded circuit, you may have a loose electrical connection in your main electrical panel or elsewhere. Loose connections are big problems and should be addressed as soon as possible. However, you should remain safe around electricity and call a professional.
A power grid problem
Lastly, talk to your neighbors and find out if they experience lights flickering in their homes at similar times. If so, it could be that the power supply to your neighborhood is inadequate or being interrupted. Call your electric company and have them come inspect the line into your home and measure for the correct voltage.
There, of course, could be other electrical problems causing your Atlantic and Cape May County area home lights to flicker, but these are the most common.
