This is usually printed next to a publication number on the manual and looks something like 02-20 (February of 2020), 01-21 (January of 2021) or 04/17 (April of 2017). Most owner's manuals have a date listed on the front page or back page of the manual. Since serial numbers may identify different years, the owner's manual can often be used to help pinpoint the date of manufacture. For example, a serial number of 'AD' could indicate the appliance was manufactured in January of 2002 or January of 2014.

The letter that corresponds with the year (2nd letter) rotates approximately every 12 years, so some serial numbers may point to different years. For example, if the serial number begins with the letters 'GA,' the appliance was manufactured in April of 2001 or April of 2013. The corresponding letters for months and years are in the chart below. Where is my model and serial number located?
