There could be a lot of reasons why your led light won’t turn on and does not work properly. Such as bad pin connections, wrong power sources, defective circuits, problems with the capacitor, and damaged wires could be are the main reason behind it. Except that there could be a problem in the grid or the electricity overflowing issue.
Below we will see what is the reason behind your LED light not working and how could you fix it.
Why LED Light Is Not Turning On and Fixing the Solutions:
There are a huge number of diverse LED lights available on the market. Most of these products share the same kind of operating system. So, the fault in LED lights that causing not to turn on are same in most cases.
Here are some common reasons why won’t your LED lights turn on and how to fix them. Let’s see.
1. Bad Pin Connection:
If your LED lights are not turning on then first check if the light pin connection is okay or not. Most of the cases the pin is not inserted correctly. To fix this problem, pull out the light and set again or replace it with another pin connection. Sometimes lights pin could be broken or bent too. However, if that’s not the problem it’s good to know that the pin connection is okay.
2. Wrong Power Sources:
Powering a LED light is quite different from powering other electric devices. It requires a variable voltage source and a constant current source. For example, a 12-voltage LED will require a 12-voltage power supply source.
Underpowering or overpowering could fuse your LED light, it could be the reason your LED is not turning on. So check that you have the right power sources connected to the LED lights.
3. Defective Circuits:
It often happens if you buy a LED light that is cheaply manufactured or use cheap parts or didn’t check the light accurately while selling.
LED normally has a long lifespan but when you use a cheap light then it won’t probably long last. Sometimes you get a defective bulb from the store and that’s why it’s not turning on.
Or, sometimes there is a defect in light power units and it burned out the power supply circuit that connects the LED diodes.
4. Problem in the Capacitor:
There is a small piece of circuitry you will see in LED lights, it’s the capacitor. Sometimes the capacitor got broken or spoils.
In that case, you don’t have to buy a whole new light to fix your problem. Just buy a new capacitor for your light. Sometimes company provides light with an extra capacitor, check if there is any extra capacitor left in the light box. These will solve your light’s capacitor problem.
5. Bulbs are too Tight for Socket:
You buy a new LED light, you bring it home, try to put it in your lamp then you see it’s too tight and doesn’t fit with your lamb socket. Now, that’s a problem, even if you manage to attach it to the socket by force, it probably won’t turn on.
In that case, you need to examine the inside brass tab of the socket. To repair the defective socket tab, turn off the socket’s power supply. Now, use needle-nose pliers to bend it upward. This will most probably solve your problem. Notice, don’t put your finger or any other object inside the socket while the power is on.
6. Damaged Wire:
That’s a very common problem we often face with LED lights. A few things could be responsible for damaged wire. First of all, you buy a light with a damaged or cut wire. It could happen from manufacturing default. You will need to return the light and get a new one instead.
In many cases, insects can damage your light wire. If the light is placed outside then the animal could cut the wire. If that’s the reason, it’s good if you can fix it by yourself or just call a professional.
7. Grid Problem:
So many things could be responsible for the gird problem. Let’s see what are those.
- Your LED light could be attached with a surge protector or an extension cord. When the electricity goes through the surge protector or extension cord, an overflow of electricity could happen in the grid. This overflow of electricity in the grid cause trouble in the lighting system. This could be the reason your light is not working.
- Or sometimes we use the same grid to connect many devices. In that matter, LED light doesn’t get electricity at a properly balanced frequency. And then your light goes off.
Here is what you can do, take a step back and look at what is on the grid. Turned off unnecessary devices and use a different grid for other electric devices. Hopefully, now your light will turn on.
8. Unusable Switch:
Sometimes it happens like you have checked everything- capacitor, light, power supply, grid, voltage, wire literally everything. In the end, you find no problem but your LED light is still turned off.
What happens is you forget to check your light switch. Probably, there is a problem with the switch. It often occurs when you use a dimmer switch that is not compatible with your light. Fix the switch and then your light will turn on.
9. Low-Quality Bulb:
Most of the problem happens with low-quality bulbs. After buying a low-quality LED bulb you may find out its dimming, flashing or worst it’s not working at all.
In that case, you can’t do anything much. You could inform the company, and hopefully, they will change the light. And next time be careful before buying a LED light, read reviews and use professional’s suggestions.
See, now you know there could be so many internal or external issues of why your LED light won’t turn on. However, LED lights are designed in a such way that it would long last. So, whatever the problem is, there is a 99% possibility that it can be fixed.
