Gateway (Router, Modem) is making a loud whining noise

My Xfinity gateway is making a very loud whining noise. I've tried all the usual things, but nothing will shut it up. The device is in the living room and I can hear it from the bedroom. It is loud and high-pitched and crazy-making. The AI Xfinity Assistant is even more crazy-making. I hope that's not the future of AI. I digress. I can't find a customer service phone number anywhere on the web site. Beyond joining the Luddites, I don't know what to do. Many thanks in advance for any help offered.

The concern is not "Community Knowledge Base" related............ Topic moved here to the proper help section.

The cooling fan is malfunctioning or the blades are loaded with dust. It's quite a common problem here. You could try blowing it out with some canned air. If that doesn't work, there is no fix other than to get it swapped out for another by them. Taking it to your local Xfinity store to be swapped out for another would be the fastest option, or ship it back for free via UPS and have them ship you another one. You can also choose to pay for a UPS pick up at https://www.ups.com/us/en/business-solutions/pickup-dropoff-options/ups-on-call-pickup.pag e or by calling 1-800-PICK-UPS.

Hello, Thank you for helping me. I find Xfinity online customer service cumbersome. So, I managed to find their phone number and they're shipping me a new gateway. Hopefully, that will resolve the problem. I'll let you know if it doesn't. Thanks again for your help, EG.
