8 Ways To Fix LED Light High Pitched Noise

LED lights are a more efficient way of being able to light up your house through different means.

They are a more cost-effective solution to making your house brighter than ever.

Most LED lights also come with a controller in order to give the user control over how his lights work.

When upgrading the smart lighting system in your home, you shouldn’t go cheap.

Saving a few bucks in the short run will only create more issues down the road where you’ll have to get the lights repaired or hire an expert.

This will create a lot of hassle, and you’ll end up spending more money overall.

So, to avoid these issues, be sure to stick with some of the more popular lighting brands like Philips, Govee, and Nanoleaf.

How to Fix LED Light High Pitched Noise?

Quite a number of users have been found complaining about facing issues while using LED lights in their houses.

According to these users, whenever the LED lights are turned on, they hear this weird high-pitched noise coming from them.

The noise gets pretty annoying at times and won’t stop. Today, we will be taking a look at all the possible reasons why you could be hearing such a noise coming from your LED light.

All the ways how you can troubleshoot this problem are also mentioned right down below:

1. Remove Dimmer

One of the first things that you will need to consider in these situations is dimmer compatibility.

Most of the time, owners are trying to adjust their new units with existing dimmers trying to take more control of the lighting conditions. However, that is not always the best idea.

You need to instead focus on the compatibility of the dimmer as the circuitry inside the LED units is more complex than your standard incandescent bulb.

So, you can’t really use a dimmer that will increase or decrease the voltage supply to the unit.

The dimmers that are compatible with the LED units focus more on engaging and disengaging the system to control the intensity of light from the unit.

Decreasing the voltage flow to dim these lights will only damage the unit while also creating this humming or high-pitched noise.

So, if you’re in the same boat and didn’t really give any thought to the dimmer, now is a good time to get a new one.

You need to rely on a fresh piece and then move forward with the unit accordingly. It might be a bit of a hassle, but you’re not left with many options here.

You will have to make the purchase of a new dimmer or replace the light switch with a traditional one.

Hopefully, that will be it when you’re dealing with the humming or high-pitched noise problem.

2. Check Connections

Next, you need to check the conditions of the connectors to isolate the issue.

If you’re sure that the dimmer or the light switch is not to blame here, then simply adjusting the connectors will do the job.

This is especially true if you’ve not serviced the electrical connections in a while.

Most of the time, you should leave this job to a professional. There are just too many reports of users electrocuting themselves while trying to adjust the system.

So, you need to avoid the same situation by hiring an electrician.

All you’re trying to do here is clean up the connectors and readjust the response from the unit. If you’re lucky, a bit of cleaning will do the trick, and the humming will stop once the power flow is optimal.

Just make sure to remove all power if you do decide to fix the connectors yourself. Otherwise, you’ll end up electrocuting yourself as well. 

3. Change Fixture

Next, you need to check the condition of the fixture to isolate this error. Most of the time, the situation with the fixture is pretty easy to deal with.

You can check for obstructions, damage, and wiring problems. All of these situations can lead to humming problems.

So, if your fixture is not in the best shape, be sure to get a replacement. There is no point in trying to make a broken fixture work.

You’ll only be wasting your time, and the LED won’t ever work with a broken fixture.

The smarter thing to do here is to reach out to the dealer and have him provide you with a compatible replacement.

He will make the troubleshooting routine much easier for you, and you won’t have to go through all of these fixes to isolate the error.

Yes, you will need to spend a bit of money, but there are no other quick fixes when the fixture is damaged.

So, be sure to reach out and let the dealer take care of this situation. Hopefully, you won’t have to worry about much after that.

4. Check Voltage Output

The voltage output should be optimal when you’re trying to ensure a consistent response from the LED unit.

If the voltage is a bit too high or a bit too low, you won’t be able to stop the high-pitched noise. So, you can rely on a multimeter or voltmeter to narrow down the error.

It won’t take much of your time, and if you do find the voltage to be the error here, then you need to check the main power source.

Most of the time, you can try a different power source but well suggest that you hire a professional for help here.

5. No Harm In Calling An Expert

If you can’t seem to figure out the issue at this point, and the voltage, as well as the hardware, is in good shape, just call an expert.

He will not only inspect the system for you but will make it much easier to isolate the errors with the device.

So, instead of wasting hours of your time, you need just hire an expert. It will cost you a few bucks, but you won’t have to worry about the system again.

So, keep that in mind and have an expert guide you through the issue. Here, you can reach out to the customer support team for your relevant brand.

Most of the established brands take customer care very seriously and will provide you with a replacement if the unit is defective.

So, if you’re not too sure about the LED hardware, rewatch out for official support. You can also test out the methods mentioned below.

6. The Problem with the LED Light

The most probable reason why this is happening could be due to there being a fault inside the circuit of the LED light.

For instance, it could be that there is some sort of fault in the driver of the LED light, due to which it is now emitting a weird noise.

It could be using double the frequency (120Hz), which is why you hear high-pitched noise.

7. Light Not Properly Mounted

Another possible reason for LED lights to emit noise is that the LED light is simply not installed or mounted properly.

You will have to check the spot wherever you have installed that LED light to see if you installed the LED light correctly.

For optimal results, we recommend that you reinstall the LED light, making sure that you mount it properly this time. Also, ensure that you install all the connections properly.

8. Replacing the Whole Unit

As you may have guessed, noises coming from the LED light are usually due to there being problems inside the circuit or driver of the light.

Unfortunately, these issues cannot be simply fixed by repairing.

This is why you might have to replace the whole unit. If the lights are still under warranty, you should be able to get a replacement unit for free.

Else, you might have to spend a few more bucks and buy a new replacement unit.

The Bottom Line:

Here are the different ways how you can fix LED light high-pitched noise. Be sure that you read through the article so that you don’t miss out on anything important.

In case of any query, all you have to do is to leave down a comment in the comment section below!

However, if the device is defective, you can’t go through any quick fixes or workarounds. The smarter thing to do would be to call the dealer and get a replacement.

The warranty is usually valid for a year. SO, if the purchase was recent, you will be able to get the new device in no time.

All you’re trying to do is make sure that the fixture, LED, wiring, connectors, and voltage output is optimal.

Keeping track of these things will make sure that you never have to deal with the same humming issues again.

Hopefully, you will be able to get through the issue in no time after fixing the power supply.
