A factory reset clears all your settings and returns your Chromecast to its original state

A factory reset wipes your Chromecast completely—removing your Wi-Fi connection, your Google account, all paired devices, and any custom settings you've made. You'll need to set it up again from scratch, the same way you did when you first took it out of the box. This is useful when you're troubleshooting a device that won't connect, preparing to sell or give away your Chromecast, or starting fresh after a major problem.

There are two ways to reset: using the physical reset button on the device itself, or using the Google Home app on your phone. The physical button is faster and works even if your Chromecast won't connect to Wi-Fi. The app method works if you still have the device paired and want to reset remotely.

Key Takeaways

  • A factory reset erases all settings, Wi-Fi connections, and paired devices, and you'll need to set up your Chromecast again from the beginning.
  • The physical reset button on your Chromecast takes about 15 seconds and works even if the device won't connect to the internet.
  • The Google Home app method works only if your Chromecast is still paired and connected to your Wi-Fi network.
  • After a reset, your Chromecast will appear as a new device in the Google Home app and you'll need to reconnect it to Wi-Fi and your Google account.

How to reset using the physical button

Every Chromecast has a small recessed reset button on the back or bottom of the device. On the standard Chromecast, it's a tiny hole next to the power cable. On Chromecast with Google TV, it's a small button on the back. You'll need a straightened paperclip or a similar thin object to press it.

Plug in your Chromecast and let it power on normally. Once it's on, use your paperclip to press and hold the reset button for about 15 seconds. The LED light on the device will start blinking orange or yellow, then turn white. When it turns white, release the button—the reset is complete. The device will restart and you'll see the setup screen appear on any TV it's connected to.

This method works whether or not your Chromecast is connected to Wi-Fi, and it's the fastest way to reset if your device is having connection problems.

How to reset using the Google Home app

If your Chromecast is still paired to your Google account and connected to Wi-Fi, you can reset it from the Google Home app on your phone or tablet. Open the app and find your Chromecast in the list of devices. Tap and hold on the device tile until a menu appears, then tap the settings icon (gear icon) in the top right corner.

Scroll down to the bottom of the settings page and tap "Reset". A confirmation message will appear asking if you're sure. Tap "Reset" again to confirm. Your Chromecast will restart and return to factory settings. This usually takes about 30 seconds.

The app method is convenient if you're already in Google Home, but it only works if the device is responding and connected. If your Chromecast won't connect to Wi-Fi or isn't showing up in the app, use the physical button instead.

What happens after you reset

Once the reset is complete, your Chromecast will appear as a new device waiting to be set up. If you have a TV connected, you'll see the setup screen with a code. Open the Google Home app on your phone, tap the plus icon to add a device, and select "Set up device". Choose "New device" and follow the prompts. The app will ask you to scan the code on your TV screen or enter it manually.

Next, you'll choose your Wi-Fi network and enter your password. Then you'll sign in with your Google account and name the device (for example, "Living Room" or "Bedroom"). Once that's done, your Chromecast is ready to use again.

When to reset instead of troubleshooting

A reset is a last resort, not a first step. Before you reset, try unplugging your Chromecast for 30 seconds and plugging it back in—this solves most connection problems. If that doesn't work, check that your Wi-Fi network is working, that your phone is on the same network, and that your Chromecast is within range of your router.

Reset your Chromecast if it won't connect to Wi-Fi even after a restart, if it's not showing up in the Google Home app, if you're giving it to someone else, or if you're selling it. A reset is also the right move if you've forgotten the Wi-Fi password it's connected to and can't change it—resetting is faster than trying to recover the connection.

Preparing to set up again after a reset

Before you reset, write down any custom settings you've made—for example, if you've changed the device name, set up a specific room, or linked it to a particular speaker. These won't transfer after a reset, so you'll need to redo them. If you're giving the device to someone else, a reset is essential because it removes your Google account and all your personal data.

Make sure you have your Wi-Fi password ready before you start the setup process. If you don't know it, you can find it on your router or in your phone's Wi-Fi settings. Having this information on hand will make the setup faster and smoother.

Frequently Asked Questions

Will a reset delete my Google account from the device?

Yes. A factory reset removes your Google account completely. After you reset, you'll need to sign in again with your Google account during setup. If you're giving the device to someone else, they'll sign in with their own account.

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

Yes, but only using the physical reset button. The Google Home app method requires an internet connection. If your Chromecast won't connect to Wi-Fi, use the paperclip and the recessed button on the back of the device.

How long does a reset take?

The physical button reset takes about 15 seconds of holding, and the device restarts in another 30 seconds. The app method takes about 30 seconds total. Setup after the reset usually takes 5 to 10 minutes, depending on your Wi-Fi speed.

Do I need to unplug my Chromecast before I reset it?

No. You can reset a powered-on Chromecast using either method. The physical button works on a live device, and the app method requires it to be powered and connected. You don't need to unplug it first.

What if the reset button doesn't work?

Make sure you're pressing the correct button—it's a small recessed hole, not a visible button on most models. Use a straightened paperclip and press firmly for the full 15 seconds. If the button still doesn't respond, try the Google Home app method instead. If neither works, the device may have a hardware problem.
