1. Use the HDMI Extender

Your FireStick includes an HDMI extender in the box for a reason. Using this extender to connect your FireStick to your TV is a smart move. Without the extender, the FireStick sits too close to the TV, which restricts airflow. Plus, your TV itself generates heat, making it harder for the FireStick to stay cool and increasing the risk of overheating. The HDMI extender creates some space between the FireStick and the TV, allowing better airflow around the device. This helps keep your FireStick cooler and reduces the chances of overheating.

2. Plug the FireStick into the Side HDMI Port of the TV

This is another key point to consider. Most TVs have multiple HDMI ports—usually located on the back and sides. Plugging your FireStick into the back panel may result in a cramped space with limited airflow. In contrast, side HDMI ports are more exposed and offer better ventilation. Even if you use the HDMI extender, it’s usually short enough to keep your FireStick tucked neatly behind the TV without ruining the clean, uncluttered look.

3. Clear Unnecessary Cache from Heavy Apps

When you use apps on your FireStick, they generate temporary cache files that take up space on the device. Larger apps, like streaming platforms such as Kodi, tend to create more cache data. Over time, this can fill up your limited storage and contribute to performance issues, including overheating.

To help keep things running smoothly, it’s a good idea to clear the cache regularly. Here’s how:

From the FireStick home screen, go to Settings.
Select Applications.
Click on Manage Installed Applications.
Choose the app (for example, NBC) that you want to clear the cache for.
Click Clear Cache.

Note: Avoid selecting Clear Data, unless you want to reset the app to its original default settings.

4. Force Close Apps Running in the Background

Sometimes, even after exiting an app—especially when it freezes or becomes unresponsive—it may continue running in the background. Pressing the Home button doesn’t always close the app entirely. These background apps continue to use system resources, which can cause the device to overheat.

To prevent this, you can force stop these apps. Here’s how:

From the FireStick home screen, go to Settings.
Select Applications.
Click Manage Installed Applications.
Choose the app you want to close (e.g., NBC).
Click Force Stop to shut it down completely.

5. Unplug Your FireStick to Refresh the System

While clearing cache and force-stopping apps can help manage overheating, doing this for each app individually can be time-consuming—especially if multiple apps are running in the background with cached data. A quicker and more effective solution is to refresh your FireStick by powering it down manually. Since FireStick doesn’t have a built-in shutdown option, you’ll need to unplug it from the power source. Leave it unplugged for a few minutes to let the device cool down completely. Then, plug it back in and power it on. This process automatically stops all running apps and clears temporary cache files, helping your device run cooler and smoother.

6. Uninstall Apps You Don’t Use

One of the major limitations of FireStick devices is their limited storage capacity—both the standard FireStick and the FireStick 4K come with only 8GB of space. Given the size of most apps and media files, that space fills up fast. When storage is nearly full, your FireStick has to work harder to operate, which can contribute to overheating. To help free up space and reduce system strain, it’s a good idea to uninstall apps you no longer need.

Method 1: Uninstall from Settings

From the FireStick home screen, go to Settings.
Select Applications.
Click Manage Installed Applications.
Choose the app you want to remove (e.g., NBC).
Click Uninstall.
Confirm by selecting Uninstall again.

Method 2: Uninstall from the Apps List

Navigate to the far right on the home screen and click See All.
Use the remote to highlight the app you want to uninstall.
Press the Menu button (three horizontal lines) on the remote.
From the popup menu in the bottom right, select Uninstall.
Click OK to confirm.

7. Delete APK Files After Installing Third-Party Apps

When you sideload third-party apps like Cinema HD, Tea TV, or Mobdro, you download their APK files onto your FireStick. After installation, these APK files are no longer needed but aren’t removed automatically. To free up space and help prevent overheating, you should delete these leftover files manually.

If you use the Downloader app to sideload, it offers a simple option to delete the APK right after installation:

After the app installs, select Done (do not click Open).
Click Delete.
Confirm by clicking Delete again to remove the APK file. If you use other tools like ES File Explorer or FileLinked for sideloading, you can use ES File Explorer to delete APK files:
Install ES File Explorer from the Amazon Store (use the search icon to find it).
Open ES File Explorer and navigate to Local > Home (the second option without the home icon) or select Internal Storage from the top menu.
Locate the folder where APK files are saved, usually the Download folder.
Highlight the APK file you want to delete by long-pressing the Select button on your FireStick remote until a checkmark appears.
Click Delete from the bottom menu.
Confirm by selecting OK to move the file to the recycle bin.

8. Reset Your FireStick if Nothing Else Works

If all else fails, performing a factory reset is the last troubleshooting step. Resetting restores your FireStick to its original factory settings, deleting all installed apps and customizations. You’ll need to set up your device from scratch, just like when you first bought it.

To reset your FireStick:

Go to Settings from the home screen.
Select My Fire TV.
Scroll down and click Reset to Factory Defaults.
Confirm by selecting Reset again.

Wrapping Up

FireStick devices are designed to handle heat well, and in my experience with multiple versions over the years, overheating is uncommon. Still, it can happen, and when it does, device performance drops significantly. Following these best practices has helped me keep my FireStick cool and running smoothly. I’m confident these solutions will help you too. Feel free to share your experiences or tips in the comments below!

Frequently Asked Questions

How can I improve the airflow around my FireStick to prevent overheating?

Using the HDMI extender included with your FireStick can help create space between the device and your TV, allowing better airflow. Also, plugging the FireStick into a side HDMI port instead of the back can expose it to more ventilation, reducing the chance of overheating.

Why does clearing cache on my FireStick help reduce overheating?

Apps on FireStick generate temporary cache files that take up storage and system resources. When cache builds up, it can cause the device to work harder and produce more heat. Regularly clearing the cache frees up storage and helps keep your FireStick running cooler.

What should I do if an app freezes and my FireStick starts overheating?

If an app freezes but you can’t exit normally, it may still be running in the background, consuming resources and causing heat buildup. You should force stop the app through the FireStick settings to close it completely and help reduce overheating.

Is it safe to unplug my FireStick to cool it down?

Yes, since FireStick doesn’t have a built-in shutdown option, unplugging it from the power source for a few minutes allows the device to cool off and clears running apps and cache, which can help resolve overheating issues.

How does uninstalling unused apps affect FireStick’s performance?

Removing apps you no longer use frees up limited storage space on your FireStick. With more free storage, the device doesn’t have to work as hard, which can prevent overheating and improve overall performance.

Can leftover APK files cause my FireStick to overheat?

Yes, APK files downloaded to install third-party apps take up valuable storage space. If not deleted after installation, these leftover files can contribute to storage overload and cause your FireStick to run hotter. Manually deleting these APKs helps maintain optimal device temperature.
