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

A factory reset wipes your Chromecast clean — it removes your Wi-Fi connection, clears any apps or preferences you've set up, and returns the device to the condition it left the factory. You'll need to set it up again from scratch, but a reset solves most problems: forgotten passwords, connection issues, sluggish performance, or preparing the device to give away or sell.

There are two ways to reset: using the physical button on the device itself, or through the Google Home app on your phone. The button method works even if your Chromecast won't connect to Wi-Fi or respond to your phone. The app method is gentler and gives you a chance to back out before the reset completes.

Key Takeaways

  • The physical reset button on your Chromecast takes about 10 to 15 seconds of holding and works even when the device is offline.
  • The Google Home app method lets you reset from your phone and requires your Chromecast to be connected to power and Wi-Fi.
  • After a reset, your Chromecast will appear as a new device in the Google Home app and you'll need to set it up with your Wi-Fi again.
  • A factory reset does not delete anything from your Google account — it only clears settings stored on the Chromecast itself.

How to reset using the physical button

Every Chromecast has a small recessed button on the back or bottom of the device. On the standard Chromecast, it's on the back near the power cable. On Chromecast with Google TV, it's on the bottom. You'll need a straightened paperclip, a ballpoint pen, or a similar thin object to reach it.

Plug in your Chromecast and let it power on normally. Once the light on the device is solid white or showing its usual status, press and hold the reset button. Keep holding it for 10 to 15 seconds. The light will flash orange, then turn white again. When it turns white, release the button — the reset is complete. The device will restart and show the setup screen, as if it just came out of the box.

If you're resetting because your Chromecast won't turn on or respond, make sure it's plugged into power and wait 30 seconds before trying again. If the light never changes color, the device may have a hardware problem and a reset won't help.

How to reset using the Google Home app

Open the Google Home app on your phone or tablet. Make sure your phone is connected to the same Wi-Fi network as your Chromecast. Tap and hold the Chromecast device tile until a menu appears, then tap the settings icon (usually a gear or three dots) in the top right corner.

Scroll down and look for "Factory reset" or "Reset device." Tap it. The app will ask you to confirm — it will tell you that all settings will be erased. Tap "Reset" or "Confirm." The Chromecast will restart, and you'll see a message saying the reset is in progress. This usually takes one to two minutes.

Once the reset finishes, the device will appear in your Google Home app as a new, unconfigured device. You can then set it up again by tapping on it and following the on-screen steps to reconnect it to Wi-Fi and your Google account.

What happens after the reset is complete

Your Chromecast will restart and display the setup screen. The device no longer remembers your Wi-Fi password, your Google account, or any custom settings you made. It's ready to be set up as if it's brand new.

To set it up again, open the Google Home app, tap the plus icon to add a device, and select "Set up device." Choose "New device" and follow the prompts. You'll enter your Wi-Fi password and sign in with your Google account. Once you're done, your Chromecast will be ready to cast from your phone, tablet, or computer again.

If you're giving the device to someone else, stop after the reset — don't set it up with your account. The new owner can set it up with their own Google account instead.

When a reset doesn't solve the problem

If your Chromecast still won't connect to Wi-Fi after a reset, the issue may be with your router or network, not the device. Try moving the Chromecast closer to your router, or restart your router by unplugging it for 30 seconds. If your router uses a 5 GHz network, switch to 2.4 GHz during setup — older Chromecast models don't support 5 GHz.

If the device won't turn on or the light never responds to the reset button, the Chromecast may have a hardware failure. Plug it into a different power outlet or try a different USB cable if you're using a Chromecast Audio or an older model that uses USB power. If it still doesn't respond, the device itself may need replacement.

Resetting a Chromecast with Google TV

Chromecast with Google TV has a slightly different reset process because it runs a full operating system. You can still use the physical button on the bottom of the device — hold it for 10 to 15 seconds until the light flashes. You can also reset through the settings menu on the TV itself: go to System > About > Reset, then confirm.

The Google Home app method also works: open the app, find your Chromecast with Google TV, tap the settings icon, scroll to "Factory reset," and confirm. All three methods produce the same result — a complete wipe of the device and a return to the setup screen.

Frequently Asked Questions

Will a factory reset delete my Google account data?

No. A factory reset only clears settings stored on the Chromecast itself — your Google account, email, photos, and other data remain untouched on Google's servers. Once you set up the Chromecast again with the same account, you'll have access to all your content again.

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

Yes. The physical button reset works whether the device is online or offline. The Google Home app method requires Wi-Fi and power, but if your Chromecast is offline, use the button on the back or bottom of the device instead.

How long does a factory reset take?

The physical button reset takes about 10 to 15 seconds of holding. The device then restarts, which takes another 30 seconds to one minute. The Google Home app reset takes one to two minutes total. After either method, you'll see the setup screen and can begin configuring the device again.

Do I need to unplug my Chromecast before resetting it?

No. Keep it plugged in and powered on. The reset button works while the device is running. Unplugging it during a reset can interrupt the process and may cause problems.

What if I forgot my Wi-Fi password and can't set up the Chromecast after the reset?

You'll need to recover your Wi-Fi password first. Log into your router's admin page on a computer or phone connected to that network, or contact your internet provider. Once you have the password, you can complete the Chromecast setup in the Google Home app.
