Not able to Control Xfinity STB


The Xfinity remote uses either RF (radio frequency) or IR (infrared) signals to control the Xfinity box.  Control Center can only send IR to Xfinity STB (see IR Learning section below). IR signals require a direct "line of sight" to work properly.  If the "line of sight" from Control Center is changed/blocked, you may need to either move the Xfinity box to a better location or try using the IR emitters.  If you are already using these, keep in mind that if the transmitter is out of alignment, IR control can become sporadic or stop working altogether.

If the Xfinity, or Control Center, is behind a closed cabinet door you will need to use and IR emitter pointed at the device in order to send a signal.

Things to check:

  • Make sure Control Center has a line-of-sight to the Xfinity device. If you are using an IR emitter, check its connection to the IR port.
  • Check that the IR emitter wasn't bumped out of alignment. The emitter should point at the sensor (IR window) of the device you intend to control.
  • Try restarting the Xfinity device and Control Center

IR can be difficult to troubleshoot because it cannot be seen with the naked eye.  Try using a digital camera (your phone's front facing camera should work) to "see" the Infrared signal blasting from Control Center as well as any attached emitters. Control Center has two emitters on the front and one on each side that will light up when issuing IR commands like Volume UP/Down. This is also a good method to determine if your IR transmitter is actually sending a signal or not.


IR Learning

Xfinity set top boxes support both RF and IR. RF is used when Xfinity is paired to the Xfinity remote. Control Center does not support learning RF so Xfinity has to be switched over to IR.  In order to switch Xfinity over to IR, its remote must be unpaired with the set top box. This will force the Xfinity remote to change over to emitting IR. Once the Xfinity remote is emitting IR, you will be able to go through the IR learning process with control center to learn the Xfinity remote. 


For Xfinity 4K users, the IR receiver is extremely directional and you must make sure to place the Control Center IR blaster right in front to get consistent control.
