Ceiling Light Not Turning On? Here’s Why!

The majority of us don’t give the ceiling lights much consideration until we try to turn them on and find that they are not functioning properly. What many people don’t realize is that broken electrical ceiling lights, in addition to the aggravation of being forced to fumble about in the dark, may be an indicator of far greater electrical issues that might end in a fire or even electrocution.

There are a variety of factors that might contribute to malfunctioning ceiling lights. Because of this, it is essential to get in touch with an electrician in a timely manner so that they can evaluate the issue. An expert electrician is going to be ready to determine the cause of the electrical issue by using deduction and reasoning to narrow down the potential causes.

Possible Causes For Broken Ceiling Lights

Until we flip the switch and discover that our ceiling lights are out, most of us don’t give them much consideration. People often don’t realize that if their ceiling lights don’t work, it might be a sign of more serious electrical issues that could lead to a catastrophe.

Ceiling lights often fail for a variety of reasons. This is why you need to get in touch with an electrician right away so they can have a look. An expert electrician is going to be capable of finding the source of the electrical issue and fix it via a process of elimination.

If you’re working with a light fixture that has failed or is not functioning right after you have already tried changing the bulb or adjusting the fixture’s socket, there are a few other factors you should test. The following represents some of the many usual aspects that contribute to problems associated with ceiling light fixtures.

Unsecured Wiring for the Switch

A wire connection that is not secure at the switch is one of the most typical causes of issues with lighting. Alternating between on and off repeatedly might cause the connection to become less secure. After turning off the electricity of your breaker panel, detach the cover from the switch, and then secure any wires that are slack. In the event that you have concerns about the connections, you should have a trained electrician evaluate the wiring.

Defective Contacts on the Switch

It’s possible that the worn-out switch contacts are to blame for the lightbulb’s on-and-off flickering. When the switch’s contacts are worn out, you may hear a crackling or sizzling sound at random intervals. Changing out the switch with a new one will fix the issue.

Recessed Ceiling Light Randomly Turns Off Then On

Are the recessed lighting fixtures in your home turning on and off at strange intervals? It’s possible that overheating is to blame. A limit switch is often used in recessed lighting to protect the light fixture from overheating in the event that the temperature within the fixture rises to a hazardous level.

First, check to see that the bulb already installed in the light fixture has the appropriate wattage, and then, if necessary, replace the bulb with one that has a lower wattage. If your issue persists, you should contact a professional electrician to have the lights inspected. It’s possible that they have a broken limit switch or some other issue.

Our resident home repair guru, John Turpin, discusses what is causing your light bulbs to fail early including, some pro DIY suggestions and solutions.

Light Socket with a Defective Tab

If you happen to look at the interior of a light socket, you will notice a brass tab that pushes up on the foundation of the bulb when the light bulb is fitted into the socket. If you screw the bulbs in too firmly, the tab may get bent down too much, prohibiting a solid connection to the light’s base.

This may happen if you screw the lights in excessively. It may result in an electrical arc, which can damage the point of contact of the light bulb and cause it to burn out much sooner than normal.

To solve the issue, turn off the power to the light via the electrical panel; alternatively, if the fixture is one that plugs into the wall, unplug it from the wall. The next step is to take a pair of needle-nose pliers and gently flex the socket tab up somewhat so that it is no longer flush with the socket’s bottom. A quarter of an inch should be sufficient.

Dimmer Switches That Aren’t Compatible

It is crucial to utilize dimmer switches which are suited for use with LED bulbs when you have converted your light fixtures to LED lights from incandescent ones. This is because LED lights are far more energy efficient than incandescent bulbs. Outdated dimmer switches had been designed exclusively for use with conventional incandescent light bulbs.

If you use compact fluorescent light bulbs or LED bulbs instead, you run the risk of inflicting damage to the wiring of the bulb, which will accelerate its demise. In order to forestall more issues, you may want to install dimmers that are compatible with LEDs.
