What Resetting Your Chromecast Does

A factory reset erases all settings, Wi-Fi passwords, and paired devices from your Chromecast and returns it to the state it was in when you first unboxed it. This is useful when you're troubleshooting connection problems, preparing to sell or give away the device, or switching it to a different Wi-Fi network and the normal connection process isn't working.

The reset itself takes about one minute, but you'll need to set up the device again from scratch afterward—which means downloading the Google Home app, connecting to your Wi-Fi, and naming the device. Plan for about 10 to 15 minutes total if you're doing this for the first time.

Key Takeaways

  • You can reset a Chromecast by holding the reset button on the back of the device for 10 to 15 seconds until the light blinks orange, then white.
  • A factory reset erases all saved Wi-Fi networks and paired devices, so you'll need to set up the Chromecast again using the Google Home app.
  • If your Chromecast is not responding and you cannot reach the reset button, you can also reset it through the Google Home app by going to device settings and selecting "Factory reset."
  • After a reset, your Chromecast will appear as an unconfigured device in the Google Home app, and you can name it and connect it to Wi-Fi as if it were brand new.

Reset Using the Physical Button on the Device

The easiest way to reset most Chromecast models is to use the small reset button on the back or bottom of the device. Locate the button—it's recessed so you'll need a straightened paperclip, a ballpoint pen, or a similar thin object to press it. Do not use a pencil, as the tip can break inside the device.

Plug the Chromecast into power and wait for the light to turn solid white, which means it's fully booted. Then press and hold the reset button for 10 to 15 seconds. You'll see the light turn orange, then blink, then turn white again. Once the light is solid white, the reset is complete and the device has returned to factory settings.

The device will no longer appear in your Google Home app or on any Wi-Fi network. If you want to use it again, you'll need to set it up as a new device using the Google Home app.

Reset Through the Google Home App

If you can still see the Chromecast in the Google Home app but it's not responding to casting commands, or if you cannot physically reach the reset button, you can reset it through the app instead. Open Google Home on your phone or tablet, find the Chromecast device in your list, and tap it to open the device details.

Tap the settings icon (three vertical dots) in the top right corner, then scroll down and select "Factory reset." The app will ask you to confirm. Tap "Factory reset" again, and the device will restart and erase all settings. This process takes about one to two minutes.

After the reset completes, the device will disappear from your Google Home app. You can then set it up again as a new device by opening Google Home, tapping the plus icon, and selecting "Set up device."

Setting Up Your Chromecast After a Reset

Once the reset is complete, your Chromecast will be in setup mode. Make sure you have the Google Home app installed on your phone or tablet—you can read it free from the Google Play Store (Android) or the Apple App Store (iOS).

Open Google Home and tap the plus icon in the top left corner. Select "Set up device," then choose "Set up a new device." The app will search for nearby Chromecast devices. When it finds yours, tap it and follow the on-screen prompts to select your Wi-Fi network and enter your password. Give the device a name (for example, "Living Room TV" or "Bedroom Chromecast") and finish the setup.

The entire setup process usually takes three to five minutes. Once it's complete, you can cast to the device from any phone, tablet, or computer on the same Wi-Fi network.

What to Do If the Reset Button Doesn't Work

If you've held the reset button for 15 seconds and the light hasn't changed, the button may be stuck or the device may not be receiving power. First, unplug the Chromecast from the power outlet, wait 30 seconds, and plug it back in. Then try the reset button again.

If the light still doesn't respond, try using a different object to press the button—sometimes a button can feel stuck even when it's not. Press firmly and hold for the full 15 seconds. If the device still doesn't reset, try the app-based reset method instead. If neither method works, the device may have a hardware problem and may need to be replaced.

Resetting Different Chromecast Models

The reset process is the same for most Chromecast devices, but the location of the reset button varies slightly. On the standard Chromecast (the round puck), the button is on the back. On Chromecast with Google TV (the larger rectangular device), the button is on the bottom. On older Chromecast Audio devices, the button is also on the bottom.

If you're not sure where the reset button is on your model, check the device itself for a small indented circle or dot. You can also search online for "[Your Model] reset button" to see a photo. The reset process and timing (10 to 15 seconds) remain the same regardless of which model you have.

Common Mistakes to Avoid

The most common mistake is not holding the reset button long enough. Many people press it for only a few seconds and then release, which doesn't trigger a reset. You need to hold it for the full 10 to 15 seconds and watch for the light to change color. If you release too early, nothing will happen and the device will stay configured.

Another mistake is trying to reset a device that isn't powered on. Make sure the Chromecast is plugged in and the light is on before you attempt a reset. If the light is off, the device isn't receiving power and the reset button won't work.

Finally, don't assume the reset failed just because the device disappears from your Google Home app when ready. That's normal—the device is supposed to disappear after a factory reset. It will reappear in the app once you set it up again.

Frequently Asked Questions

Will resetting my Chromecast delete anything from my phone or computer?

No. A Chromecast reset only affects the Chromecast device itself. Your phone, computer, and any apps on them will not be changed. The Chromecast straightforward forgets its Wi-Fi password and any devices that were paired with it.

Do I need to reset my Chromecast if I'm just changing Wi-Fi networks?

Not usually. You can change the Wi-Fi network through the Google Home app without resetting. Open the app, tap the Chromecast device, go to settings, and select "Wi-Fi." Choose your new network and enter the password. A full factory reset is only necessary if the normal Wi-Fi change process isn't working.

How long does it take to set up a Chromecast after resetting it?

The setup process typically takes 5 to 10 minutes from start to finish. This includes downloading the Google Home app (if you don't have it), connecting to your Wi-Fi network, and naming the device. The actual reset takes only about one minute.

Can I reset my Chromecast if it's not connected to Wi-Fi?

Yes. The physical reset button works whether or not the device is connected to Wi-Fi. However, the app-based reset method requires the Chromecast to be connected to Wi-Fi and visible in your Google Home app. If your device is offline and not showing up in the app, use the physical reset button instead.

What should I do if my Chromecast won't turn on after a reset?

Make sure the power cable is firmly plugged into both the Chromecast and the wall outlet. Try a different power outlet to rule out a problem with the outlet itself. If the device still won't turn on, try unplugging it for one full minute, then plugging it back in. If it remains unresponsive, the device may have a hardware issue.
