It can be quite frustrating when you are trying to pair your subwoofer with your soundbar or some other device and it simply doesn’t work. In this article, we focus on some of the most common fixes for your subwoofer not pairing issue.
By the way, if your issue is that your subwoofer keeps connecting to your soundbar and disconnecting, please check out this guide. In the guide, we explain how to troubleshoot when your subwoofer keeps disconnecting from your soundbar.
Why Subwoofers May Fail To Pair
1. Wear And Tear
Subwoofers just like any other electronic products may fail due to usage, wear and tear. Due to their complex design and cheaper subwoofers using low-quality materials, subs can always die or fail within their very first few years of usage especially if heavily used.
2. Connection Problems
For subwoofers to pair safely with other devices, they must be powered, and in good working condition.
The lack of power is therefore one of the major causes of subwoofer not pairing. For instance, if the amperage reaching the electromagnetic coil is too low, the functionality of the sub can be easily altered causing it to fail to work properly.
Another problem that is likely to cause your sub not to pair is overheating. Subwoofers may be overhead when used heavily over a long time.
This may cause some features of the sub to stop working properly. If you suspect that overheating is the culprit, place the sub in a well-ventilated area, and stop prolonged usage.
4. Short Circuit
The other major cause is the short circuit which interrupts the signal from reaching the destination.
When no signal is transmitted, or no power altogether, the sub will not produce any sound and will not pair with other devices successfully. Short circuits can be fixed easily by professionals depending on the type of damage.
Samsung Soundbar Subwoofer Won’t Link
Linking your Samsung soundbar and subwoofer should be seamlessly easy, and simple. However, at some point, they may not link due to interference or something wrong with the connection. Here are some of the suggestions from our audio experts to help you fix the connection.
1. Subwoofer Power
Sometimes, the sub may not link to the soundbar due to a failed or lose power connection between the outlet and the sub. The first step is to check if the subwoofer is powered on. If the sub is not powered on, check that the power cord is correctly and securely connected. You can also unplug the power cable and plug it back again, tightly.
2. Firmware Version
Also, the devices may fail to connect if the firmware of the soundbar or sub are out of date. You can check the firmware of your Samsung soundbar using the remote control.
Begin by powering the subwoofer and turning it on. Locate the gear-like button on the remote control and press it once. Then, press the button again for about 30 seconds and wait for some numbers to display.
Check out the numbers that follow “B” signifying the firmware version of the soundbar. To update the version, download the file via the SmartThings app or using the USB port.
3. Speaker Test
If you are using soundbar 2020 models and later, you will be bale to access speaker tests. Ensure the subwoofer remains off while you run speaker tests on the subwoofer.
Locate the right button on the big circular control at the center of the remote control, and press and hold it for more than ten seconds to start the test.
4. Range Of Soundbar And Subwoofer
Another reason why your soundbar and sub won’t link could be the rage. As a rule of the thumb, two devices should be placed at a maximum wireless range of not more than 33 feet. If the standard range is exceeded, there might be interference in the connection.
Besides, if there is an obstacle between the soundbar and the subwoofer, it might foil the connection. Additionally, the soundbar will not link with your sub if it uses the same wireless frequency as another device in close proximity.
To troubleshoot the connection with these problems, ensure the devices are placed closer to each other, there’s no barrier between them, and there’s no device in proximity with the soundbar that uses a similar frequency.

You can also reset the power on the subwoofer and try to use it again. Unplug its power cord from the mains supply and then plug it back. Power it on and wait for it to reconnect to the soundbar. You can then listen to some music and check if the issue is resolved.
What To Do When The Subwoofer Isn’t Working Properly
When the subwoofer fails to pair with the soundbar successfully, there are a number of likely causes of the problem. Let’s look at some of the fixes you can perform to fix a subwoofer that is not working properly.
1. Check Outlets, Power Cable And Fuse
Inspect the wires and connections from the subwoofer, and soundbar. Most subwoofers have a “standby” LED that indicates active power.
If you can’t see this light on, check the wall socket to ensure the cable is securely plugged and all the associated switches flipped to the on position. Also, check that the cables are not damaged or defective.
You can unplug the cable and plug it back to check if the issue is fixed. If not, test the power outlet with a different device such as a lamp. If the lamp doesn’t light, then the outlet has an issue that needs to be checked by an electrician.
If it works, you can request service from the support center or professional technician. If your budget is not strained already, replace the soundbar or subwoofer with a new one.
2. Press The ID Set Button
Using a sharp object, press the ID set button located at the back of the subwoofer. If the LINK light blinks, try the connection again to link the soundbar.
