Why Does My Amazon Fire TV Stick Keep Restarting and Rebooting on Its Own
- Device overheating from poor ventilation or enclosed cabinet
- Insufficient power from a low-amperage USB port or adapter
- Corrupted app data or system cache causing crashes
Problem Description
Your Amazon Fire TV Stick keeps restarting and rebooting randomly during use. The screen goes black, the Fire TV logo appears, and the device boots up again. This may happen multiple times per hour or once every few hours. The restarts interrupt streaming and can occur during any activity including watching shows, navigating menus, or when the device is idle.
Symptoms
- Screen goes black and Fire TV logo appears followed by reboot
- Device restarts in the middle of streaming video
- Restart loop where the device boots then immediately restarts again
- Device gets very hot before each restart
- Restart happens when launching specific apps
- Audio cuts out for a few seconds before the restart occurs
Recognize these? Here's what usually causes it.
Common Causes
- Device overheating from poor ventilation or enclosed cabinet
- Insufficient power from a low-amperage USB port or adapter
- Corrupted app data or system cache causing crashes
- HDMI port not providing enough power for CEC wake functions
- Outdated Fire OS software with known stability bugs
- Faulty HDMI connection causing signal loss triggering reboot
Most fixes happen in the first 3 steps.
If your Fire TV Stick is in a restart loop and you cannot access settings, hold the select and play buttons on the remote simultaneously for 10 seconds to force a factory reset. This erases all data.

Step-by-Step Solution
Check Power Supply
The Fire TV Stick requires the included power adapter plugged into a wall outlet. Powering it from a TV USB port does not provide sufficient amperage and causes random restarts, especially during high-demand activities like 4K streaming. Verify you are using the original adapter or a 5V 1A adapter at minimum. For the 4K Max and Cube models, use the included higher-amperage adapter. Inspect the USB cable for damage or fraying that could cause intermittent power loss.

Feel the Fire TV Stick body. If it is very hot to the touch, overheating is likely causing the restarts. Use the included HDMI extender cable to move the Stick away from the hot area behind the TV. Ensure the device is not trapped between the TV and the wall with no airflow. Do not cover the device with anything. If the device is in an enclosed media cabinet, open the cabinet doors or install a small USB fan to improve circulation.
Clear Cache and App Data
Go to Settings, Applications, Manage Installed Applications. Select each app you use frequently and choose Clear Cache. If a specific app triggers the restart, also select Clear Data for that app. You will need to sign back into the app after clearing data. After clearing caches for all major apps, restart the Fire TV Stick by going to Settings, My Fire TV, Restart. This clears the system cache as well.
Update Fire OS
Go to Settings, My Fire TV, About, and select Check for Updates. Install any available Fire OS updates. Amazon regularly releases updates that fix stability issues and restart bugs. After updating, the device will restart once to apply the update. Monitor for random restarts over the next 24 hours. If the update process itself causes a restart loop, unplug the device for 5 minutes, then plug it back in to allow the update to complete.
Factory Reset If Persistent
If restarts continue after all steps, a factory reset may be needed. Go to Settings, My Fire TV, Reset to Factory Defaults. Confirm the reset. The device will erase all data, apps, and settings and return to its initial setup state. After the reset, set up the device and install apps one at a time, using it for a day between each app installation. If a specific app triggers the restarts, that app is the cause and should be reported to the app developer.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Disable HDMI CEC in Fire TV settings if your TV turns the Fire TV Stick on and off with the TV. CEC power cycling can sometimes trigger restart loops on certain TV and HDMI configurations.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
