Whirlpool serial number with year code C: 1993 or 2023

In the Whirlpool 1990 to present format the year letter C means 1993 or 2023. Two or more years share this letter, so the plate's other dates or the official lookup settle it.

• A Whirlpool serial number with year code C was built in 1993 or 2023 (1990 to present format; source: building-center.org).
• TABLE CONFLICT for 1999-2010: building-center (the table already in formats.json) says I=1999 J=2000 K=2001 L=2002 M=2003 P=2004 R=2005 S=2006 T=2007 U=2008 W=2009 Y=2010; appliancedates says J=1999 K=2000 L=2001 M=2002 P=2003 R=2004 S=2005 T=2006 U=2007 W=2008 Y=2009 0=2010; Sears PartsDirect (official Sears, current) says J=1999 K=2000 L=2001 M=2002 N=2003 P=2004 R=2005 T=2006 U=2007 W=2008 Y=2009 0=2010. Two of three sources put K=2000, Y=2009 and 0=2010 (the building-center chart has no 0 and uses I, which Whirlpool otherwise skips) so treat the building-center table as off-by-one for 1999-2010 until a Whirlpool document settles it. All three agree X=1990..H=1998 and 1-9=2011-2019, X=2020, A=2021.. Letters repeat every 30 years, so model era is needed to pick 1991 vs 2021. Worked examples: MX06404786 = 2020 wk 6 (appliancedates, Maytag dryer MED7230HW0); MB1402320 = 1992 wk 14 (appliancedates Kenmore); RA01xxxx = wk 1 of 1991 or 2021, FM644xxxx = wk 44 of 1986 or 2016 (Sears).
