Light Not Working? Here’s 10 Reasons Why!

As a rule, a light bulb and light fixture are very reliable, and so will very rarely break, but if one breaks and you don’t know how to fix, this could be an issue, as such, this article will cover 10 potential reasons and fixes for a broken light fixture or bulb!

Plug or Wall Switch

sometimes, it is possible for the fixture to be loose, meaning the power connection could not be there, so check if the light bulb could be screwed in more and that the switch is on.

Circuit Breaker

is it just the specific light bulb that is not turning on? or are other things in the room also not turning on? if that is the case, then it is highly possible that a fuse was tripped, so if so, you should be able to go over to your fuse box and switch it back on.

Light Bulb

Sometimes it can just be the light bulb that has gone, some are built to last 10 years while others break almost immediately, not all light bulbs are born equal. If none of the previous suggestions written above have worked, then just try changing the light bulb and see the results that gives before moving on.

Socket tab

For this suggestion, we cannot stress enough how necessary it is to have turned off the power in the house before doing this, missing this step seriously puts your health at risk. Once you are certain the power is off, try bending the tab inside of the plug socket, as sometimes that gets pressed in too far and subsequently does not make contact with the plug for power, if the power is still on when you try this, you are literally in for a shock!

Fixture or Lamp Switch

Now that the easiest tests have failed, it’s time to concentrate on the electrical wiring. If the fixture is a light with an in-line switch (the kind with a wheel or toggle inside a little plastic case that clamps onto the cord), fiddle around with the switch and listen for any buzzing or other irregular sound when you turn the wheel. These go bad all the time. If you notice anything wrong, change the switch with a matching part (simply follow the producer’s directions). You may have to replace the cable, too, if the copper electrical wiring is damaged.


Both plug-in light cords and cables that tether hanging fixtures can come loose from the socket terminals, the internal component electrical wiring, or the plug terminals. Move the cord and/or component into a variety of contortions (get imaginative!) to see if the light goes on even for a minute. If so, examine the cord connections. If those look ok, change the cord.


Testing the socket for power is as simple as purchasing a circuit tester, which are dirt cheap and starting the tests! While instructions may vary, this is normally the way it is tested: With the power to the component on, touch one tester probe to the metal socket tab and the other to the threaded metal sleeve that the bulb screws into. If the tester illuminate, the socket is ok; if not, it might be a bad socket, a loose (or fried) wire en route to the socket, or a bad wall switch.

Wall Switch and Fixture Cable

If you are familiar with household circuitry and know your way around a switch, then the next step is the above has not solved your issue would be to examine the wall switch and wire connections in between the switch and fixture cable television. Which again can be done with the same circuit tester we used for the above steps.

Fixture Wiring

If we can see that the switch is getting powered and is sending that power to the fixture, then the next step is to take that fixture apart to check the socket terminal and any other circuitry connections for any noticeable issues. You will likely see that is is a bad socket or that it is actually the case that the wires themselves have fried, which almost always happens due to an appliance taking more wattage than the fixture itself can handle, causing the electrics to take more energy and quickly fry out under the pressure.

Circuit Cable

If all of the above have not worked, then it is a good possibility there is an issue somewhere along the circuit path. and for this, you will really need to hire a beaconsfield electrician to see what the problem is and resolve it.
