Trane Parts Beginning with BLW
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'.
