Hallway Light Wasnt Working but Its Working Again

We all take for granted how user-friendly it can be that we can plough on or off lights someday we need to. Only what happens when your lights stop working and you can't figure out why? Was information technology the bulb that blew? Did something fall off within of the light switch? Do nosotros take mice eating the wires?

Hopefully, you don't take mice eating your wires, or else you have a whole different trouble. In near cases, the trouble is something that yous can remedy yourself without having to call an electrician.

Chances are, your lights have stopped working because of one these 4 common reasons:

The light fixture was unplugged.
The low-cal bulbs burnt out.
The circuit billow or GFI got tripped.
The socket tab got flattened, and information technology'due south not making contact with the light bulb.

Some other common reasons might include:

The low-cal switch has stopped working.
The Calorie-free fixture has stopped working.
The wires are not connected properly.
The ballast needs replaced.

Safety Starting time

Before attempting to gear up whatsoever problems with your lite switch or light sockets, remember to turn the billowoff first to avoid electrocuting or called-for yourself. A helpful tool to invest in is a voltage tester; they are inexpensive and volition alert you if there is any ability nevertheless going to the light switch or electrical outlets. It'due south also smart to work with rubber gloves and to make sure that you lot aren't standing anywhere near a wet surface. However, do remember that information technology's ever a much smarter thought to consult an practiced rather than try to fix electrical issues yourself.

Why Light Bulbs Burn Out

Over time, the constant surging of electricity through a lightbulb will clothing downwards the filaments on the inside. Eventually, over fourth dimension, the filaments will become thinner and more brittle, until a single surge of electricity will either crusade the filaments to break, burn, or melt completely. That is why your lightbulb will of a sudden get out, or make a popping audio right subsequently flipping the switch on.

If this happens, replacing the lightbulb itself is likely the only solution that's needed. If your lightbulb is flickering, nonetheless, the lite bulb may be okay, and you may just demand to tighten it in its socket to get information technology to stay on.

Why Would a Low-cal Switch Suddenly Stop Working?

Light switches tin can go bad over fourth dimension, and when that happens, the easiest solution would be to supersede information technology since they are inexpensive. But before you practice replace the switch, you should be aware that there are other reasons why the switch might have stopped working.

No Power

A light switch could lose power if the circuit billow has been tripped, which will preclude electricity from flowing to the switch. Circuit breakers will trip as an automatic response to wires heating up. If it's safe to turn the power dorsum on, you lot can reset the breaker, or printing the reset button on your footing error interrupter (GFI) sockets.

Brusk Circuits

A mutual reason for a light switch to cease working is for example, when a "hot" wire comes in contact with a "neutral wire," a large amount of current will flow through the circuit and crusade the excursion breaker to brusk out and shut itself off before something bad could happen.

Short circuits are dangerous considering they have the potential to starting time a fire.

Loose Wires

Sometimes over time, the wires within their terminals volition brainstorm to loosen. Loose wires can crusade the lights to flicker when the switch is turned on or cause the switch not to work at all. With the breaker turned off, you can go to your billow box, remove the baseplate, and tighten upward the wires in their terminals.

If the wires aren't that loose, you can disconnect them from the switch, twist them together with pliers, and use the voltage tester to check if power is running through the wires or not. If it is, the trouble is nearly likely not with the wires, simply with the switch itself. In that example, you'll take to have the entire low-cal switch replaced.

Excursion Overload

If y'all take an one-time light switch or tend to keep all the lights on in your house, you might be at risk of overloading the circuit past demanding more electricity than your circuit breaker can provide. A circuit overload can atomic number 82 to short circuits and blown fuses due to the excessive amount of heat all the power creates at once.

Ground Faults

Similar a short circuit, a basis fault occurs when a hot wire touches the grounding wire and blows the grounding fuse. A ground mistake might cause an unusual smell or a burnt socket. Unless y'all're an electrician, this needs to exist stock-still by a professional person and not tampered with on your own.

Practise Calorie-free Sockets Go Bad?

Low-cal sockets can get bad. One of the more common reasons is when a lite bulb is screwed down and tightened likewise much, causing the contact to squish down and get flattened. If the light seedling is no longer able to connect with the contact, the light can not get power.

A flattened socket tab or damaged socket may as well occur if you've been unknowingly using the wrong type of lightbulb for the socket in question. Information technology is possible to heighten this tab back up, only make sure that the ability is off before touching it.

The socket may also be discolored to signal a problem. Discoloration may be caused by called-for from faulty wiring behind the socket, but information technology tin can also be caused by collecting rust over time that prevents the seedling from connecting with the tab in the socket.

What Would Cause a Lite Fixture To Cease Working?

Below are some common reasons for a light fixture to terminate working.

Burnt Bulb or Socket

As mentioned previously, light bulbs and light sockets tin get bad. The problem with your lighting fixture not working might be as uncomplicated as a burnt-out lightbulb or a dirty/flattened socket. Irresolute the bulb or socket might exist required to correct the problem.

Faulty Wiring

Like with a light switch, the wiring in a light fixture can experience a brusk excursion, excursion overload, or a ground mistake, if the wiring is non properly connected to the light, if it's loose, or if it is improperly protected. The wires can too end up touching the metallic parts of the fixture and redirecting the electricity away from the bulb. Bad wiring within a calorie-free fixture can exist a potential fire gamble or cause for electrocution, so either call an skilful in to ready the wiring or get a new low-cal fixture altogether.

Problems with an Outlet

If your light fixture plugs into an electrical outlet via a wall plug, the problem may prevarication inside the outlet rather than the light fixture. The outlet could possess whatsoever of the wiring problems listed in a higher place, or the circuit may be prone to tripping due to the outlet being in areas with wet, such as a bathroom or on the wall of a kitchen counter.

These circuits can get reset if plugged into a GFI socket, just if the light in your fixture doesn't turn on when plugged into the outlet, it is most likely a trouble with the bulb, the light socket, or the wiring in the walls.

How Do I Know If My Calorie-free Socket is Working?

If you have changed your light bulb and you accept ruled out that it'due south not a bad bulb, and the circuit breaker wasn't tripped, the culprit might be the lite socket not working. Here are some simple tips that you can follow to check the socket.

Continuity Test

A continuity test is a basic examination that you lot can perform when troubleshooting whatsoever light fixture, and information technology will assistance determine whether the electrical circuit is practiced or bad, continuous or broken. First, you want to check to see if there is a voltage available at the lighting outlet box or non. For this, you tin use either a digital multimeter or a non-contact voltage tester to check for Ac voltage. The non-contact voltage tester is recommended for homeowners since information technology does not crave you to touch a probe on live wires carrying a current. Instead, all you have to practise is bring the noncontact voltage tester close to the lighting fixture with the light switch on.

Troubleshooting Incandescent Fixtures

Outset, start by turning off the circuit breaker at the service console, so there is no power going to the lighting fixture. Next, carefully remove the light fixture from the outlet box and double-check the circuit once more using a voltage tester to make sure that you lot have turned off the right excursion breaker (video below showing how to test for this).

Here is a quick video showing you how to exam that at that place is no power:

One time you have confirmed that there is no power going to the fixture, you can disconnect the fixture wires then you can and then check the continuity. Use a digital multimeter set to the ohms part (Ω), check the white fixture wire for continuity by placing a probe to the blank metallic on the white wire, and another probe to the metal shell inside the low-cal socket. Test multiple spots all around the metal shell. If in that location is continuity, the multimeter will display "0.000" on the screen. If the socket is bad, the screen on the multimeter volition brandish "O.L."

Next, check the continuity between the black fixture wire and the contumely part at the bottom of the light socket. Again, the screen on the multimeter will display "0.000" if its good, and "O.L." if information technology's bad. If y'all get whatsoever bad reading during the tests, you know in that location is a problem with the light socket and it needs to exist changed.

If the continuity test shows that the light socket is OK, but the light withal doesn't work using a new light bulb, and then what is nigh likely happening is that the brass contact at the bottom of the calorie-free socket got flattened and the light bulb is not able to come into contact with it. With the circuit billow nevertheless turn off, the brass plate will need to be pried away from the base of the socket.

How Exercise You Ready a Light Socket?

Sometimes a lite socket can go bad, and rather than replacing the unabridged light fixture, you can supervene upon the socket instead. It'south a fair, piece of cake task, only before you effort to modify it, you demand to turn off the excursion breaker at the service console. Information technology's e'er wise to double-check with either a digital multimeter voltage tester or a non-contact voltage tester to confirm that yous take completely shut off the power before going nigh any wiring.

Here is a very helpful video that will help explain how to modify a light socket.

What Are The Signs of a Bad Anchor?

When people see a fluorescent seedling flickering, their get-go idea is normally that the bulb volition presently need to be replaced; however, it may non be a bad calorie-free bulb at all, only rather, the anchor on the fixture needs to be repaired or replaced.

Below are some commons signs that the ballast on your fixture is not working correctly.

Flickering

A strobing or flickering calorie-free is the near obvious sign of a bad anchor. It could hateful a bad bulb, just if y'all have merely replaced the bulb or tube and it's still flickering, and so the problem is near likely a bad ballast.

Buzzing/Humming Sounds

If you are hearing any buzzing or humming sounds coming from the fixture, it is a sign that the ballast is about to go. Noticing any sounds is a good time to examination the anchor and make any repairs necessary.

Different Levels of Light

Bulbs can modify colors throughout their lifespan, peculiarly in tubes, but if you are noticing night areas or just overall inconsistent lighting, that could exist a sign of a bad ballast.

Starting Filibuster

A light that is slow to come on is some other mutual sign of a bad ballast. Continue an eye on the lights and come across if they have longer then usual to reach its total brightness.

Depression Lighting Output

Lastly, depression output lighting or dimmer than normal lighting is a sign of a bad ballast. This could too mean the bulb has reached its lifespan, simply information technology'southward of import to check the anchor first before replacing it.

Some less common causes are:

Burn marks on the casing
Casings that look bloated
Leaking oil (this applies to a magnetic anchor)

What Causes a Bad Ballast?

Ballasts will typically concluding near 20 years if under the proper atmospheric condition. Knowing what causes a ballast to go bad is important in keeping lite fixtures in proficient working order to maximize how many years you lot can get out of it.

The most common reason's for a ballast to neglect is due to heat and moisture. Farthermost temperature changes tin can impact the ballast, whether information technology be too hot or also cold. However, heat and condensation (high humidity) will cause corrosion, which can damage the ballast.

The good news is, some fixtures offer a UL rating that is better suited for damp/wet locations. When placing your fixture, take note of where it is getting mounted and brand sure that it can withstand temperature changes likewise as high humidity levels.

Repairing a cleaved ballast is typically quick and easy if you are comfortable working with light fixtures. The whole procedure should take yous around 10 minutes to complete. There are several videos and tutorials online that can hands guide you through the process. If you lot are unsure or non comfy with the repairs, brand sure to contact a professional for help.
