Troubleshooting All the Common Legrand Dimmer Problems

Although smart home technology has successfully made our lives easier, for the most part, there are still some issues that you may end up running into every now and then.

We have been receiving plenty of complaints from users regarding the Legrand dimmer light switches.

These users complained about how they have been facing different problems with the device.

Today, we will be using this article in order to focus on telling you the procedure for troubleshooting the most common Legrand dimmer switch problems.

All of the problems, along with their solutions, are mentioned right down below:

  1. Weird Buzzing Sound

Possibly the most common problem that we see many users face while trying to operate any dimmer light switch is that they start hearing a weird buzzing sound coming from their lights as soon as they attempt to dim their lights.

The main reason behind the buzzing sound is the type of dimmer you may be using as well as the wiring status.

So, you should check up on the wiring status and make sure that the connections are in good shape.

If there is too much load on the circuit, the unit will start malfunctioning, and you will not be able to get any response out of the device.

For this reason, you need to always start out by isolating the issue with the wiring connection and proceed with the situation from there.

Similarly, it could be due to the reason that your dimmer may have aged or it is of a low quality.

Low-quality dimmers are known to cause a loud audible buzzing sound whenever you use them to dim your lights.

So, if you want to resolve the buzzing sound, you will have to either get your dimmer checked or get it replaced with a newer one.

Just be sure that you purchase a good quality dimmer light switch this time around.

  1. Lights are Not Dimming

Another really common problem caused by dimmer lights is that even though the dimmer turns on, it fails to dim the user’s lights.

No matter how many times the user attempts to turn or adjust the dimmer, it does not have any effect on the lights whatsoever.

In this case, there are quite a few reasons which could lead to you facing this issue. For instance, it could be that you have not installed the dimmer correctly.

Likewise, it is also possible that your lights are not dimming simply due to the fact that they don’t support the feature.

There’s also the possibility of you using a dimmer switch that isn’t really compatible with your lights.

Lastly, the dimmer could be faulty. Either way, you will have to check for each and every reason listed in this step, as any of them could be the case for your issue.

  1. App Not Responding

The application will also present some issues, and these errors are not that serious in most conditions.

So, you will have to take a look at the minor errors in the application version and the OS version on our mobile device.

In most conditions, the fix is as simple as reinstalling the application.

So, all that you need to do is remove the application from your phone and then install the latest version on your phone. It all comes down to making sure that there are no programming bugs.

On the other hand, if you’re already stuck in the same errors and the application is updated, then you should just reset the app by wiping all stored data.

So, be sure to access the application settings and remove all of the stored data from your device.

That will fix the situation ninety percent of the time, and you will not have to bother with the same application errors again. 

Lastly, you need to also check the OS version on the mobile unit. If the OS version on your mobile is outdated, then you can’t really expect a response from the smart device.

So, to fix that, you will need to first confirm the issue by installing the application on a different phone.

If the issue does get fixed as you install the application on the new phone, you will be sure that the OS version is to blame.

From there, you can proceed with the update on the current device and then install the application one more time.

That will likely be it when you’re struggling to get a response out of the Legrand dimmer switch. 

  1. Dimmers Unreachable

Next, you might also come across some owners complaining about the dimmers being unreachable.

This problem can almost always be traced back to connection errors, and you will have to check on the network status to isolate the issue.

One of the more common mistakes that owners make here is that they will set up the router near the unit and then move it out of range, expecting the same level of performance.

Sadly, that is not the case with most of the units, and you will have to keep track of the signal strength.

This includes moving the router back into range and making sure that there are minimal interferences.

Even if you are not that sure about the router, bringing the unit closer to the device will help you get a better response out of the dimmer.

So, your first step should be to always focus on the network connection and limit the issues to signal strength.

If you’re lucky, the problem will be fixed fairly easily, and you will not have to do much besides limiting the number of wireless devices and bringing the router back in range.

However, if you think that the problem is more related to the programming of the plug itself and there are no signa related issues, then your only job is to reset the system.

It will take a while but you can pair up the dimmer once again with the smart application.

Hopefully, you will avoid a ton of errors down the road that way, and won’t have to deal with the same complications.

  1. Lights are Flickering

One last really common problem with dimmer switches is that the lights will randomly start flickering whenever turned on or adjusted using the switch.

According to most users who face this issue, the lights keep on flickering until they are finally turned off.

We strongly recommend you start by checking the light bulb itself.

The first reason for the issue could be the bulb itself, as it could be faulty. In the same way, using a really old or poor-quality dimmer switch can also lead to you facing this issue.

Loose or poor wiring could also be the cause, as it could be that you haven’t installed the dimmer switches properly. 

If that is so, then you will have to proceed to reinstall the dimmer by making sure you don’t leave any loose wiring inside it.

Just in case, we also recommend that you check the ratings of your bulb as well as the dimmer.

The Bottom Line:

These are the most common problems that you may face with the Legrand dimmer light switch, along with the ways you can fix them.

Be sure to read each and every single piece of instruction that we have mentioned in the article!

Nine times out of ten, you will be able to fix all the issues by following the basic steps offered here.

It will be pretty easy to address the majority of these errors as long as you’re sure about the hardware side of things. So, if you find your unit to be in good shape, fixing it won’t be hard for you.

Similarly, you need to just keep track of the installation and make sure that the dimmer itself is not damaged.

You can’t expect a response from the unit when there are issues with the wiring, power supply, basic connection, and pairing process.

So, you just have to be a bit more mindful of the installation routine, and you will be able to avoid the majority of these errors.

On the other hand, you always have the option of reaching out to the dealer, and he will give you more perspective on the situation.
