GE Age??

Evap in attic: Model #: BWB918G100C0, Serial #: 383380722. Can anyone help with the age? If so, can you tell me how you figured it out? Thanks!

General Electric: Age is the last 3 digits of the serial number. First digit being the year
and the second and third digits being the month. Example xxxxx241 = 41st week of 1982,
92, 02 etc., xxxxx533 = 33rd week of 1985, 95, 05 etc
Hope this helps

Exactly what I needed. Thanks so much!!
