How To Fix Nintendo Switch Joy-Con Controller Won’t Sync | New in 2025
Many Nintendo Switch users experience controller syncing problems all the time and fortunately, the issue is temporary for most. If your Joy-Con controller won’t sync at all and the problem won’t go away on its own, this article should help.
Find out the potential solutions that you can try by spending a few minutes with this troubleshooting guide.
Why would a Joy-Con controller fail to sync?
Your Nintendo Switch Joy-Con controller may encounter pairing or syncing issues for a variety of reasons. Let’s check some of the commonly encountered causes for controller connection problems on Nintendo Switch below.
Bluetooth signal interference.
The Nintendo Switch uses industry standard Bluetooth technology to communicate with its Joy-Cons. If you’re having trouble pairing or syncing any or all controllers to the console, the first thing that you should check is the possibility of a Bluetooth signal interference. This means that the console and controllers are not talking to each other may be due to absence of Bluetooth connectivity, or perhaps another Bluetooth device is cutting off the signal.
Random console or controller bug.
The Switch may disconnect from its controllers due to a random bug. Sometimes, a controller’s firmware, the mini-OS that helps the hardware work with the console, may develop a glitch. This is rare and is usually easily fixable by simply re-pairing.
Hardware malfunction.
If your Joy-Con is damaged, like when it’s hit hard or dropped, it may break a component in the logic board. Depending on the severity of the damage, a quick repair may or may not help.
