Vibration Check

Controller Vibration Test: What This Tool Actually Does

If a game stopped rumbling, or you only feel it on one side of the controller, the issue is almost always one of the two rumble motors failing or losing power. The vibration tester at the top of this page sends signals directly to your controller through the browser, so you can check each motor in isolation, run side-by-side comparisons, and tune the intensity to find out exactly what's working and what isn't — without launching a game.

The test runs locally in your browser using the Gamepad API. There is nothing to install, no driver to download, and no data leaves your device. Connect any controller with a rumble motor — Xbox, PS5 DualSense, PS4 DualShock, Switch Pro Controller, or a generic PC pad — and the tester picks it up automatically the moment you press a button.

How to Run the Vibration Test Correctly

The tester above gives you control over which motor fires, how strong it is, and how long it runs. To get a result you can trust, follow this short sequence rather than just hitting buttons randomly — a methodical test tells you exactly which motor has the problem.

Reading the Results

Once you've finished the sequence, you'll fall into one of four common outcomes. Match what you felt against the cards below to know what to do next.

Why Controller Vibration Stops Working

Rumble issues come from a small set of well-known causes. Diagnosing which one you have tells you whether to dig into the controller yourself, send it for repair, or move on to a new pad.

Worn or broken motor brushes

The vibration motors inside game controllers are small unbalanced DC motors. Like all brushed DC motors, the carbon brushes that deliver current to the spinning shaft wear down over time. Worn brushes produce weaker rumble, intermittent operation at low intensities, and eventually no rumble at all. There's no software fix — the motor needs replacement, which on most controllers means soldering a new one in.

Loose or broken solder joints

Both motors are wired to the controller's main board with two solder points each. If a controller has been dropped repeatedly, or has spent time in a hot car, those joints can fracture. The motor itself is fine, but it's no longer getting power. This is one of the most fixable failures — if you're comfortable with a soldering iron, re-flowing the joint takes a minute and often restores full function.

Firmware or driver issues

Sometimes the motors are fine and the controller just isn't being told to rumble. On PC, this usually means an outdated controller driver or a game using an older input API that doesn't support your pad's rumble protocol. On PS5 specifically, a small percentage of DualSense units develop firmware issues after major updates that disable haptics until the controller is reset.

Battery or power issues (wireless controllers)

Rumble motors draw significant current. On a wireless controller with a low battery, the system will throttle or disable vibration to preserve power even at 30–40% battery remaining. If your rumble suddenly weakens or vanishes mid-session, check battery level before assuming hardware failure — the issue may disappear once the controller is fully charged. You can verify this with our Battery Check tool.

PS5 DualSense Haptics vs Standard Rumble

If you own a PS5 DualSense, the situation is more complex than a standard rumble check. The DualSense doesn't actually use two unbalanced motors like older controllers — it uses two voice coil actuators that can produce finely controlled vibrations of variable frequency and amplitude. This is what Sony calls "haptic feedback," and it's why DualSense rumble feels qualitatively different from a DualShock 4 or Xbox controller.

The browser's Gamepad API uses a standard "dual-rumble" interface, which means the DualSense's advanced haptic system gets simplified down to a strong/weak two-channel signal during this test. That's a limitation of the web standard, not the controller. If both channels respond on a DualSense, your haptics hardware is working — you just won't feel the full nuance you'd get inside a game like Astro's Playroom or Returnal.

How to Fix Controller Vibration That Stopped Working

If the test confirms one or both motors are dead, work through the fixes from cheapest to most involved.

1. Check the easy stuff first

Restart the controller (hold the central button for ten seconds, or use the reset pinhole on the back of a DualSense). Charge it to 100%. Try a different cable or USB port. Test on a different device. About one in five "broken vibration" reports turn out to be a low battery, a flaky cable, or a software glitch that clears with a restart.

2. Verify the issue isn't game-side

Some games either don't support rumble at all or have vibration disabled by default in their settings. Test rumble in at least two known-good games or with the tester on this page before concluding the hardware is at fault.

3. Re-pair and update

Forget and re-pair the controller from your console/PC. On Xbox, run the Accessories app to check for and install controller firmware updates. On PS5, Settings → Accessories → Controllers shows the current DualSense firmware version. On PC, install the latest official driver from the controller manufacturer if available.

4. Open it up (advanced)

If the test still shows one side completely dead and the controller is out of warranty, opening it and inspecting the motor wires is the next step. Both DualSense and Xbox controllers have plenty of YouTube teardown tutorials. Look for two small motors mounted in each grip, each with red and black wires going to the main board. A loose connection usually shows up immediately as a black scorch mark or a wire that's snapped clean off. Re-solder, or order a replacement motor for $5–10 and swap it.

5. Replace the controller

If the motor is fine but firmly mounted and the wires look intact, the controller's rumble driver chip on the main board has likely failed. That's a board-level repair that costs almost as much as a new controller — not worth doing unless you specifically want to keep this exact controller. For a 2+ year old pad, replacement is usually the rational choice.

Once you've finished testing rumble, it's worth running a few of the other free checks on the same controller. The Joystick Test reveals stick drift, the Gamepad Tester confirms every button and trigger registers, and the Latency Test measures your controller's response time in milliseconds.
