Monogram Appliance - How to Determine the Age or Manufacture Date

The manufacturing date is coded into the serial number (not the model number) of each appliance. Our serial numbers begin with two letters followed by six numbers. The first letter identifies the month and the second letter identifies the year an appliance was manufactured. The corresponding letters for months and years are in the chart below. For example, if the serial number begins with the letters GA, the appliance was manufactured in April of 2001 or April of 2013.
 

Determining the Age or Manufacture Date

Note: Every twelve years we run through the alphabet letters listed in the chart and start over at letter A. So, some serial numbers may be duplicated and correspond with different years. For example, a serial number of AD could be January 2002 or January 2014.
 
  • Since serial numbers may identify different years, the Owner's Manual can often be used to help pinpoint the date of manufacture. Most Owner's Manuals have a date listed on the front page or back page of the manual. 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). The print date may not exactly match the month and year from your serial number. As long as it is close to the serial number, it will verify that you have determined the correct age. You can check the Owner's Manual for the specific model you own for a publication date.
If you are still unsure of the year of manufacture, Contact Us with your model and serial number for further assistance.
