CFM56-7B T25 probe question

chaps,


there has been a number issues of the CFM56-7B having throttle roll backs due to erroneous signals to FADEC due to icing of the T25 probes. I had this discussion with another chap who said that the probe wasn't heated i.e. there is no heating element. It was my understanding that there is and there is a corresponding circuit breaker to match. does anyone have a schematic to show the probe is heated. I do not recall it was heated by engine bleed.


look forward to the responses from the brains trusts!
