The quickest way to restart Chromecast
Unplug the Chromecast from power for 30 seconds, then plug it back in. That is the full restart. Wait another 30 seconds after plugging it back in for the device to boot up completely — you will see the Google logo appear on your screen or hear the startup sound, depending on your model.
This solves most problems: casting that stops working, apps that freeze, connection drops, or a device that stops responding to your phone or remote. A power restart clears the device's memory and resets its connection to your network without erasing any of your settings or saved information.
If you cannot reach the power outlet easily, some Chromecast models also have a reset button on the device itself. Press and hold it for about 10 seconds until you see lights flash or hear a sound. This performs the same restart as unplugging.
Key Takeaways
- Unplugging your Chromecast for 30 seconds and plugging it back in fixes most casting problems without losing your settings.
- A power restart clears temporary glitches like frozen apps, dropped connections, or devices that stop responding to commands.
- If your Chromecast has a reset button, holding it for 10 seconds does the same thing as unplugging.
- Wait 30 seconds after plugging back in before trying to cast again — the device needs time to fully boot up.
When to restart versus when to factory reset
A restart and a factory reset are different actions with different results. A restart (unplugging or using the reset button) keeps all your settings, saved networks, and linked accounts. A factory reset erases everything and returns the device to its original state, as if it just came out of the box.
Restart first. Most problems — casting failures, app crashes, slow performance, connection issues — clear up with a straightforward restart. Only do a factory reset if a restart does not work and you are willing to set up the device again from scratch. Factory reset is the last step, not the first.
Restarting Chromecast from your phone or computer
You can also restart Chromecast without touching the device itself. Open the Google Home app on your phone or tablet, find your Chromecast in the list of devices, tap the three dots in the corner, and select "Restart." The app will send a command to restart the device remotely.
This method works if your Chromecast is mounted high on a wall or tucked behind a TV where unplugging is inconvenient. The restart takes the same amount of time — about 30 to 60 seconds total — and has the same effect as unplugging it manually.
What to do if restart does not fix the problem
If restarting does not restore casting, check that your Chromecast and your phone or computer are on the same Wi-Fi network. Open the Google Home app and look at the network name shown under your device. If it is different from the network your phone is connected to, reconnect your Chromecast to the correct network through the app settings.
If casting still does not work after a restart and both devices are on the same network, restart your Wi-Fi router as well. Unplug the router for 30 seconds, plug it back in, and wait for all lights to stabilize before trying to cast again. Router restarts fix connection problems that affect multiple devices.
If the device still will not cast after restarting both the Chromecast and the router, try casting from a different app or a different phone to narrow down whether the problem is with the Chromecast itself or with one specific app. Some apps have their own casting bugs that a restart cannot fix.
Restarting different Chromecast models
Chromecast with Google TV has a power button on the remote — press and hold it for about 10 seconds to restart. Chromecast Audio (the older speaker model) has a small reset button on the back; hold it for 10 seconds. Standard Chromecast and Chromecast Ultra have no buttons, so unplugging is the only manual option.
Regardless of model, unplugging always works. If your remote is lost or the button is stuck, unplug the device from the outlet. The effect is identical across all models.
How long a restart takes and what to expect
From the moment you unplug to the moment the device is ready to cast again: about 60 to 90 seconds. The first 30 seconds is the device powering down. The next 30 to 60 seconds is it booting back up. You will see the Google logo appear on your TV screen, or the device will make a startup sound, or both — this signals that the restart is complete.
Do not try to cast during this time. Wait until the startup animation or sound finishes before opening the Google Home app or casting from another device. Casting too early can interrupt the boot process and cause the device to restart again.
Frequently Asked Questions
Will restarting Chromecast erase my saved networks or passwords?
No. A restart keeps all your settings, saved Wi-Fi networks, and linked Google accounts. Only a factory reset erases those. If you want to keep your setup, restart — do not factory reset.
Can I restart Chromecast while it is actively casting?
Yes, but it will stop the cast when ready. The video or music will stop playing. Unplug it only if casting is frozen and will not stop any other way. If casting is working normally, let it finish before restarting.
What if my Chromecast does not turn back on after I unplug it?
Wait a full minute before plugging it back in — sometimes the device needs longer to fully power down. If it still does not turn on after plugging back in, try a different outlet to rule out a power problem. If it remains off, the device may have a hardware failure.
Do I need to restart Chromecast regularly for maintenance?
No. Restart only when you notice a problem — casting stops working, apps freeze, or the device stops responding. Regular restarts are not necessary and do not improve performance if nothing is broken.
