The cooling fan is likely to be 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.page or by calling 1-800-PICK-UPS.
