The most common causes of Fire Stick restarts

A Fire Stick that restarts on its own usually has one of three problems: overheating, a software glitch that needs clearing, or an app that crashes and forces a reboot. Most of the time you can fix it yourself in under five minutes by doing a force stop or a restart from the settings menu — you do not need to unplug it or call Amazon support.

Overheating happens because the Fire Stick's processor gets too warm, usually from sitting in a closed cabinet, behind a TV, or in a room that is already hot. A software glitch happens when the system gets stuck in a loop and reboots to try to fix itself. A bad app happens when one program crashes repeatedly and takes the whole device down with it.

Key Takeaways

  • Most restarts come from overheating, a stuck app, or a software glitch — all fixable without sending the device back.
  • Check whether the Fire Stick is in an enclosed space or getting blocked airflow, and move it to open air if it is.
  • Force stop the app that crashes before the restart, or do a full restart of the Fire Stick from Settings > Device > Restart.
  • If restarts keep happening after you clear the cache and restart, the device may have a hardware fault and need replacement.

Check the Fire Stick's location and airflow

The Fire Stick is a small device with a processor that generates heat. If it sits inside a closed cabinet, behind your TV, or in a room above 95 degrees Fahrenheit, it will overheat and restart to protect itself. Move the Fire Stick to an open shelf or mount it on the wall where air can flow around it freely. If your room is very hot, move it to a cooler spot or wait until the room cools down before using it.

You can also check the back of the Fire Stick for dust buildup. If dust is blocking the vents, gently wipe it away with a dry cloth. Do not use water or compressed air, which can damage the electronics inside.

Force stop the app that is crashing

If the Fire Stick restarts right after you open a specific app, that app is likely crashing and taking the system down. To stop this, go to Settings > Applications > Manage Installed Applications, find the app that crashes, and select Force Stop. Then go back to the home screen and try opening a different app to see if the Fire Stick stays on.

If the Fire Stick stays on with other apps, the problem app is the culprit. You can uninstall it and reinstall it fresh, or check the app's store page to see if there is a newer version. Many crashes happen because an app is out of date and does not work with your Fire Stick's current software.

Restart the Fire Stick from the settings menu

A full restart clears temporary files and resets the software without erasing your apps or account. Go to Settings > Device > Restart and select Restart. The Fire Stick will shut down and turn back on, which usually takes about two minutes. Wait for it to fully boot up before opening any apps.

If you restart and the problem stops, the issue was a software glitch that cleared itself. If restarts start again after a few days, the glitch may be coming back, and you may need to restart again or look at which app you were using when it started.

Clear the cache and storage if restarts are frequent

Over time, apps store temporary files called cache that can pile up and slow the Fire Stick down or cause crashes. To clear cache, go to Settings > Applications > Manage Installed Applications, select each app you use often, and choose Clear Cache. This does not delete your login information or saved data — it just removes temporary files.

If your Fire Stick is running low on storage space, it can also restart. Go to Settings > Device > Storage to see how much space is left. If you have less than 1 GB free, uninstall apps you do not use regularly. You can always reinstall them later from the Amazon Appstore.

Check for software updates

Amazon releases updates that fix bugs and improve stability. Go to Settings > Device > About and look for an option to check for updates. If an update is waiting, install it and let the Fire Stick restart when prompted. Do not unplug it during the update — wait for it to finish on its own, which usually takes five to ten minutes.

If you have automatic updates turned on, the Fire Stick may restart on its own to install an update. This is normal and not a sign of a problem. You can turn off automatic updates in Settings > Device > System Update if you prefer to install them manually, but keeping them on helps prevent crashes and security issues.

When the Fire Stick needs replacement

If you have moved the Fire Stick to open air, force stopped crashing apps, restarted the device, and cleared the cache, but restarts keep happening every few minutes, the device likely has a hardware fault. This usually means the processor or power supply is failing and cannot be fixed at home.

Contact Amazon support with the serial number of your Fire Stick (found in Settings > Device > About). If the device is still under the one-year limited warranty, Amazon will replace it at no cost. If it is out of warranty, you can buy a new Fire Stick or Fire Stick 4K, which cost between $40 and $60 depending on the model.

Frequently Asked Questions

Why does my Fire Stick restart right after I turn it on?

This usually means the device is overheating or a system update is installing. Move the Fire Stick to open air and wait a few minutes. If it keeps restarting, unplug it for 30 seconds, plug it back in, and let it fully boot up before opening any apps. If restarts continue, a hardware fault may be present.

Can a bad WiFi connection cause restarts?

A weak WiFi signal can cause apps to crash, which may trigger a restart, but it does not usually cause the Fire Stick itself to restart repeatedly. If you suspect WiFi is the problem, move the Fire Stick closer to your router or restart your router by unplugging it for 30 seconds. If restarts stop, WiFi was the issue.

Should I unplug my Fire Stick if it keeps restarting?

Unplugging it for 30 seconds can help clear a software glitch, but it is not a long-term fix. After you plug it back in, go to Settings > Device > Restart to do a proper restart. If restarts happen again after a few days, the problem is likely an app or a hardware fault, not a temporary glitch.

Will a factory reset stop the restarts?

A factory reset erases all your apps and account information and returns the Fire Stick to its original state. It can fix restarts caused by a corrupted app or software glitch, but it takes about 30 minutes and you will have to set up the device again. Try the steps above first — they work for most restart problems without erasing anything.
