Carrier infinity control SYSTXCCUID01-B is showing a new outside sensor communication error once every day, for the last 3 days. Problem won't Dismiss. System is only one year old, and used very sparingly.
There should be a little black sensor bulb outside either on the unit normally under the electrical panel or inside it. It sound like the wire has come off or been disconected. It needs that on to properly run. Your control is trying to communicate with the outdoor unit and can not.
Wish it were that easy - my NEW Carrier Infinity has had this problem for over a month and no one from Carrier or Sears seems to know what to do or how to solve thew problem. I can't even get a technician to come out again. At first simply shutting the system down for an hour would work now there is no way to over-ride the error message and we are roasting! Do you know any one at Carrier that really cares about this problem? Thanks

I found the black outside temperature sensor. I unplugged it from the circuit board, and the yellow LED on the board began flashing the correct fault code, "53". I took an OHM reading on the sensor, and got a 70K ohm reading. I plugged the sensor back into the board and the flashing led ceased. I now have a solid yellow led. I would feel better if I had a solid Green led showing, but all I have is a solid Yellow led showing. IS IT POSSIBLE THAT THE SENSOR IS NO GOOD?
