Whirlpool is a major manufacturer of home appliances. Besides selling appliances under its own name, the company owns a range of other brands, including Kitchen Aid, Roper and Sub Zero. Whirlpool appliances, including stoves, code the manufacture date into the serial number. For a Whirlpool stove, the model number will include the year the stove model was introduced but not the year of production.
Find the model number and serial number tag on the stove. Write down the serial number.
Find the date code in the serial number. The code will be the second or third letter followed by two numeric digits. Starting at the beginning of the serial number, the first two numerals are the correct digits plus the immediately preceding letter.
Determine the year of manufacture from the selected letter. Whirlpool has used letter codes for the production year since 1990. The letters plus corresponding year are X: 1990, A through H: 1991 through 1998, J through M: 1999 to 2002, P: 2003, R through U: 2004 through 2008, W: 2008 and Y: 2009.
Use the two numerals as the week of manufacture. For example, if the date code in you stove serial number is T24, the stove was manufactured in the 24th week of 2006.
