My xb7 fan is not working

user_rs7n4s Thank you for reaching out to the Xfinity Community Forums. I'd be happy to help. The fan in an XB7 does not run all the time, so not hearing it spin isn't always a sign that something is wrong. That said, I'd like to learn a little more about what you're seeing. Is the gateway getting unusually hot, or are you experiencing any internet, Wi-Fi, or performance issues? Any additional details you can provide will help us point you in the right direction and determine whether further troubleshooting is needed. I look forward to your reply.
