In order to find the age of a Whirlpool built appliance you will need the serial number from the appliance. Since Whirlpool manufactures appliances under many different names, this may work with some of these brand names also:
Whirlpool, Kenmore (Sears), Maytag (Newer models), Kitchen Aid, Estate, Inglis, Roper, Amana, Jenn Air, Crosley and more.
Serial Number Example:
1st Digit: Where the appliance was manufactured. C = Clyde, OH.
2nd Digit: Year Manufactured. R = 2004
3rd & 4th Digit: Week the appliance was manufactured. 39 = 39th week of the year.
5th-9th Digit: Manufacture order that week
