Why Are My Lights Flickering?

Flickering lights can be concerning, frustrating, and sometimes even frightening. They can disrupt daily routines, create an unsettling atmosphere, and signal potential electrical problems. There are many reasons why lights may dim and flicker, and routine electrical service as well as a functional electrical system are essential in preventing this annoying occurrence.

In this brief article brought to you by Mr. Electric, we explore some potential reasons why your lights are flickering. If you’d rather have a certified electrician come in and investigate, then call Mr. Electric. We’re here to schedule an appointment or arrange emergency electrical repair service for as soon as possible.

Loose Bulbs

The most straightforward cause of flickering lights is a loose bulb. When a bulb isn’t securely screwed into the socket, it can cause intermittent contact which often leads to flickering. Ensure that all bulbs are properly tightened but be careful not to overtighten as this can damage the bulb or socket.

Faulty Light Switches

Light switches can wear out over time, especially if they are frequently used. A worn or defective switch may not maintain a solid connection, causing the light to flicker. Replacing old or malfunctioning switches can often resolve this issue.

Loose Wiring

Loose or frayed wiring is a more serious cause of flickering lights and poses a significant fire hazard as well. Loose connections at the fixture, in the electrical panel, or along the circuit can cause lights to flicker. If you suspect loose wiring, you should contact a licensed electrician to inspect and repair the issue promptly.

Overloaded Circuits

An overloaded circuit happens when too many appliances or devices are drawing power from the same circuit. This can cause the voltage to fluctuate, leading to flickering lights. Redistributing the electrical load or upgrading the electrical system to handle more power can fix this problem.

Voltage Fluctuations

Voltage fluctuations, or power surges, can cause lights to flicker. These fluctuations can be due to large appliances cycling on and off, faulty wiring, or issues with the utility service. Using surge protectors and having an affordable electrician check for wiring issues can help manage voltage fluctuations.

Incompatible Dimmer Switches

If you’ve recently installed LED bulbs and they flicker when used with a dimmer switch, the issue may be compatibility. Not all dimmer switches are designed to work with LED lights. Upgrading to a dimmer switch specifically designed for LEDs can eliminate flickering.

Aging or Faulty Electrical System

Older homes with outdated electrical systems are more prone to flickering lights due to worn-out wiring, corroded connections, or insufficient electrical capacity. Upgrading the electrical system can provide a more reliable and safer power supply.

Why Routine Electrical Service is Key

Routine electrical service is vital for maintaining a functional and safe electrical system. Regular inspections by a licensed electrician can identify potential issues before they become serious problems.

During an inspection, an electrician will check for loose connections, inspect wiring conditions, test circuit breakers, and ensure that your electrical system meets current safety standards. They may recommend solutions ranging from a lighting replacement to more complex things like an electrical panel replacement.
