The three ways to reset your Chromecast
You can reset a Chromecast in three ways: using the Google Home app on your phone, holding the reset button on the device itself, or unplugging it and performing a soft reset. The method you choose depends on whether your Chromecast still responds to commands and whether you have the physical device in front of you.
A factory reset clears all your saved networks, paired devices, and account information. After reset, your Chromecast will behave as though it just came out of the box — you'll need to set it up again from the beginning using the Google Home app.
The most common reason to reset is when your Chromecast stops responding to casting commands, won't connect to Wi-Fi, or you're preparing to sell or give away the device. A reset also fixes persistent bugs that survive a straightforward restart.
Key Takeaways
- The Google Home app method works if your Chromecast is still powered on and connected to your network, and takes about two minutes.
- The physical reset button on the back or bottom of your device works even if the Chromecast is unresponsive, but you must hold it for 10 to 15 seconds.
- A soft reset — unplugging the device for 30 seconds — fixes most connection problems without erasing your settings.
- After any factory reset, you must set up your Chromecast again using the Google Home app before you can cast to it.
Reset using the Google Home app
Open the Google Home app on your phone or tablet. Find your Chromecast in the list of devices — it will show the name you gave it during setup. Tap and hold the device tile until a menu appears at the bottom of the screen.
Tap the settings icon (a gear or three dots, depending on your device type). Scroll down to the bottom of the settings page and select "Reset" or "Factory reset". A confirmation message will appear asking if you're sure. Tap "Reset" again to confirm.
The Chromecast will restart and return to its factory state. This usually takes one to two minutes. Once the light on the device stops flashing, the reset is complete. You can then set it up again by opening Google Home, tapping the plus icon, and selecting "Set up device".
Reset using the physical button on your device
Locate the reset button on your Chromecast. On most models, it's a small recessed button on the back or bottom of the device. You may need a paperclip or the tip of a pen to press it, since it sits below the surface to prevent accidental presses.
With the Chromecast powered on, press and hold the reset button for 10 to 15 seconds. The light on the device will flash and change color — usually from white to amber or red. Keep holding until the light stops flashing and returns to a steady state, which signals the reset is complete.
This method works even if your Chromecast is not connected to Wi-Fi or is otherwise unresponsive. It's the most reliable way to reset if the Google Home app method doesn't work or if you don't have the app installed.
Soft reset: when you don't need a factory reset
If your Chromecast is having minor problems — slow casting, occasional disconnections, or delayed response — a soft reset often fixes the issue without erasing your setup. Unplug the power cable from the back of the device and wait 30 seconds. Then plug it back in.
The device will restart with all your settings, networks, and paired devices intact. This takes about one to two minutes. A soft reset is worth trying before a factory reset because it solves most temporary glitches and saves you the time of setting up the device again.
What to do after a factory reset
Once your Chromecast has been reset, it will no longer appear in your Google Home app. Open the app and tap the plus icon in the top left corner. Select "Set up device" and choose "Set up a new device".
The app will search for your Chromecast and display it by name (usually "Chromecast" or "Chromecast Audio" depending on the model). Tap the device you want to set up. You'll be asked to confirm the setup code shown on your TV or speaker, then select your Wi-Fi network and enter the password.
Once you've entered your network information, the Chromecast will connect and you'll be able to cast to it again. The entire setup process takes about five minutes.
Troubleshooting a reset that doesn't work
If the Google Home app method doesn't show a reset option, your Chromecast may not be responding to the app. In this case, use the physical reset button instead. Make sure you're holding it long enough — at least 10 seconds — and watch for the light to change color.
If the physical button doesn't work, try unplugging the device for a full minute, then plug it back in. Some Chromecasts require a longer wait before they respond to a reset command. If the device still won't reset after these steps, it may have a hardware problem and may need to be replaced.
If you reset your Chromecast but it won't connect to Wi-Fi during setup, move it closer to your router and make sure you're entering the correct password. Some older routers don't work well with newer Chromecast models — if this is the case, check Google's support page for your specific model to see if there are known compatibility issues.
Resetting before you sell or give away your device
Always perform a factory reset before handing your Chromecast to someone else or selling it. A factory reset removes your Google account, saved networks, and any personal information from the device. Without this step, the new owner could potentially access your account or networks.
After you reset the device, unplug it and let the new owner set it up themselves using their own Google Home app and account. This ensures they have full control and you have no remaining access to the device.
Frequently Asked Questions
Will a factory reset delete my Google account from other devices?
No. A factory reset only removes your account from that specific Chromecast. Your Google account and all your other devices remain unchanged. You can still cast from your phone and other devices to other Chromecasts on your network.
How long does a factory reset take?
A factory reset usually takes one to two minutes from the moment you confirm the reset until the device is ready to be set up again. The light will flash during this time. Once it stops flashing and returns to a steady state, the reset is complete.
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. The Google Home app method requires a Wi-Fi connection, but the button method does not.
What if I forget my Wi-Fi password after resetting?
You'll need to know your Wi-Fi password to set up the Chromecast again. If you don't remember it, you can reset your router or check your router's settings page using a computer or phone connected to the network. Your internet provider can also help you recover your password.
Do I need to unplug my Chromecast before pressing the reset button?
No. Press the reset button while the device is powered on and plugged in. The device will restart as part of the reset process. Unplugging it is only necessary for a soft reset, which is different from a factory reset.
