I have an American Standard Freedom 80 gas furnace / AC unit model # AUD080C936H3. This unit is about 9 years old and all original parts still operating. The flame sensor is getting worst for wear. I have cleaned the flame sensor a couple of times and am concerned that it will fail and need replaced in the near future. I would like to know if someone out there can tell me the part number and a phone number where I can purchase a replacement. The existing flame sensor has the following numbers on it: PSE-T12; B340888; and 9701. I have tried googling for the part but have had no matches. The existing flame sensor comes out about 1.5" from the porcelain and bends 90 degrees to go in front of the flame port.
Thank you in advance for any assistance.
