Over heating issue need help

Greetings DEETEE1 

Welcome to the Roku Community and thanks for posting regarding your Roku device overheating. 

First off, are you using a Roku Streaming Stick or another Roku device? Please be aware that the Roku Streaming Stick is the only device that you will be able to order a HDMI extender for. Additionally, when inputting the serial number into the HDMI extender form, we would recommend using the serial provided in Settings > System > About, as sometimes the serial number listed on the Roku device may be the device ID and not the serial number.

For more information about what to do when your Roku device is overheating, visit our Support page here: Fix an overheating issue

Please keep us posted what you find out and we will be more than happy to continue assisting you.

Thanks,
Danny
