Trane and American Standard Parts
Trane part numbers have the format of CCCnnnnn, where CCC is a three character prefix denoting the type of part: i.e. CNT = Control board, MOT = Motor and so on.
The prefix is followed by five numbers. If your part has only four numbers on it, add a zero to the beginning of the four numbers. For example, if your part shows a 'CNT 3797', add a '0' to the beginning of the '3797' and remove the blank between the prefix and the number and you get 'CNT03797'.
Searching for your part number is the fastest way locate your part.
Clicking on the picture or title will get you more information about the part.
American Standard is the same as Trane.
