The fastest way to restart your Chromecast

Unplug the power cable from the back of your Chromecast device for 30 seconds, then plug it back in. Wait for the light on the device to stop blinking and turn solid — this takes about one to two minutes. Your Chromecast is now restarted.

This is the method that fixes most problems: streaming that freezes, connection drops, or the device not responding to your phone or remote. A power restart clears the device's memory and resets its connection to your Wi-Fi network without erasing any of your settings or saved information.

If your Chromecast is built into a TV or speaker, you cannot unplug it directly. In that case, move to the next method instead.

Key Takeaways

  • Unplugging the power cable for 30 seconds is the fastest fix for freezing, connection problems, or unresponsive Chromecast devices.
  • If your Chromecast is built into a TV or speaker, use the Google Home app on your phone to restart it remotely.
  • A factory reset erases all your settings and paired devices, so use it only if a power restart does not solve the problem.
  • After restarting, your Chromecast reconnects to Wi-Fi automatically if you have not changed your network password.

Restarting through the Google Home app

Open the Google Home app on your phone or tablet. Tap the device you want to restart — it will show as a card with the Chromecast name and a picture. Tap the three dots in the top right corner of the card, then scroll down and tap Restart.

The app will confirm that the restart is in progress. Your Chromecast will disconnect from the app for about one to two minutes while it restarts. You do not need to be on the same Wi-Fi network as the Chromecast to use this method, though the app must be able to reach the device.

This method works for all Chromecast models, including those built into TVs and speakers. It is also useful if you cannot physically reach the device to unplug it.

Factory reset: when to use it and what it does

A factory reset erases all your settings, paired devices, and Wi-Fi information from the Chromecast. Use this only if a power restart or app restart does not fix the problem, or if you are selling or giving away the device.

To factory reset through the Google Home app, open the app, tap the device card, tap the three dots, scroll down, and tap Factory reset. The app will ask you to confirm. The reset takes about one to two minutes.

After a factory reset, you will need to set up the Chromecast again from the beginning: connect it to Wi-Fi, sign in to your Google account, and pair it with your phone or remote. All your previous settings are gone.

What to do if the restart does not work

If your Chromecast still does not respond after a power restart, try unplugging it for a full two minutes instead of 30 seconds. Plug it back in and wait for the light to turn solid before testing it again.

If the device still does not work, check that your Wi-Fi network is running and that other devices can connect to it. If your Wi-Fi is down, restart your router by unplugging it for 30 seconds, then plug it back in and wait for it to reconnect.

If the Chromecast light does not turn on at all after you plug it in, the power cable or USB port may be damaged. Try a different USB cable or power adapter if you have one available. If the device still does not power on, it may need to be replaced.

Why your Chromecast might need a restart

Chromecast devices run software that can develop small glitches over time, especially if they have been on for days or weeks without restarting. A restart clears the device's temporary memory and forces it to reconnect to your Wi-Fi network from scratch.

Common reasons to restart include: the device stops responding to casting commands, video or audio freezes mid-stream, the device drops off your Wi-Fi network, or the Google Home app shows the device as offline even though it is plugged in and powered on.

Restarting does not erase your settings

A power restart or app restart does not erase any of your saved information. Your Google account, paired devices, Wi-Fi password, and any customized settings stay in place. The device straightforward stops and starts its software, the same way restarting a computer does not erase your files.

The only method that erases everything is a factory reset. If you are not doing a factory reset, you can restart as often as you need without losing anything.

Frequently Asked Questions

How long does a Chromecast restart take?

A restart takes about one to two minutes from the moment you unplug the device or tap restart in the app. The light on the device will blink while it is restarting and turn solid when it is done. You can start casting again as soon as the light is solid.

Will restarting my Chromecast disconnect it from Wi-Fi?

No. After a restart, your Chromecast automatically reconnects to the same Wi-Fi network using the password you set up before. You do not need to enter the password again unless you have changed it on your router.

Can I restart a Chromecast that is built into my TV?

Yes. Use the Google Home app method — open the app, tap the device, tap the three dots, and tap restart. You cannot unplug a built-in Chromecast, so the app is your only option.

What is the difference between a restart and a factory reset?

A restart stops and starts the device's software but keeps all your settings and paired devices. A factory reset erases everything and returns the device to the state it was in when new. Use restart first; use factory reset only if restart does not solve the problem.

Do I need to be home to restart my Chromecast?

No, if you use the Google Home app method. You can restart a Chromecast remotely from anywhere as long as the app can reach the device. If you want to unplug it, you will need to be physically present.
