Maytag serial number with year code B: 1966 or 1990

In the Maytag 1966 to 2010 format the year letter B means 1966 or 1990. Two or more years share this letter, so the plate's other dates or the official lookup settle it.

• A Maytag serial number with year code B was built in 1966 or 1990 (1966 to 2010 format; source: building-center.org).
• Pre-Whirlpool Maytag Corporation format (Maytag, Admiral, Magic Chef, Jenn-Air, Amana 2002-2006, Norge, Hardwick, Crosley, Caloric, Modern Maid). Year letters repeat every 24 years (E = 1980 or 2004); the letters are NOT alphabetical by year. Whirlpool phased it out after the 2006 purchase but appliancedates shows a Jenn-Air range 16240783NR built Sept 2008 in this code, so the era overlaps the Whirlpool style through ~2010. Worked examples: 12772864EL = Jun 2004 (Amana dryer NDE2330AYW), 17657865KM = Jun 1994 (Jenn-Air S156), 12150883QY = Nov 1996, 16240783NR = Sep 2008, 717486QX = Dec 1972 (6-digit sequence), 19346732EG = Apr 1980/2004 (building-center). Alliance Laundry still uses this exact letter cycle on its European-built machines (see Speed Queen rule).
