If your Amazon Echo Dot 3rd Generation is experiencing hardware issues, but the app is still functioning, your motherboard may need to be replaced. Follow this guide to do so.
The motherboard, or main board, of the Echo Dot is the control center from which your device takes all its commands. If your main board is not functioning properly, it will need to be replaced.
