How old is my Amana appliance?

Type the serial number from the Amana label to see when it was built. Amana units are built by Whirlpool since 2006, so the serials follow that company's format.

Reading a Amana serial number

Maytag owned Amana from 2001 to 2006, and those units end in two date letters, like EL for June 2004. Since 2006 Amana uses the Whirlpool code.

Amana units built before 2002 use an older code the checker does not read yet.

About Amana

  • Raytheon sold its home appliance business, which included Amana, to Goodman in 1997.
  • Goodman sold the Amana appliance business to Maytag in 2001 and kept Amana heating and air conditioning. An Amana furnace or AC is a different company’s product.
  • Whirlpool still runs a refrigeration plant in Amana, Iowa.

Whirlpool plant, year and week

Used 1970s to today. Example: C60842986

The serial starts with a plant code of one or two letters. The next character is the year and the two digits after it are the week. Year codes repeat: digits stand for the 1970s, 1980s or 2010s, and the 1990s letters came back in 2020.

Worked example: C60842986 fits Week 8 of 1976 (around February) or Week 8 of 1986 (around February) or Week 8 of 2016 (around February). The page above explains how to tell which.

The full lookup tables are on the Whirlpool page, since Amana uses the same code.

Maytag year and month letters at the end

Used 1966 to the late 2000s. Example: 12772864EL

Older Maytag, Jenn-Air, Amana and Admiral serials are all digits with two letters at the end. The first of those letters is the year and the second is the month. The year letters repeat every 24 years.

Worked example: 12772864EL fits June 1980 or June 2004. The page above explains how to tell which.
