How Monogram serial numbers encode the date
Monogram does not print the manufacture date in plain text on most units — it is encoded into the serial number. The decoder recognises one format for this brand:
Repeating letter date code
The 2nd character of the serial number is the year code. The 1st character is the month.
Applies to serial numbers of at least 2 characters.
| Year code | Means |
|---|---|
| F | 1991 · 2003 · 2015 · 2027 |
| G | 1980 · 1992 · 2004 · 2016 · 2028 |
| H | 1981 · 1993 · 2005 · 2017 · 2029 |
| L | 1982 · 1994 · 2006 · 2018 · 2030 |
| M | 1983 · 1995 · 2007 · 2019 · 2031 |
| R | 1984 · 1996 · 2008 · 2020 · 2032 |
| S | 1985 · 1997 · 2009 · 2021 |
| T | 1986 · 1998 · 2010 · 2022 |
| V | 1987 · 1999 · 2011 · 2023 |
| Z | 1988 · 2000 · 2012 · 2024 |
| A | 1989 · 2001 · 2013 · 2025 |

Why the year can be ambiguous
Monogram reuses the same year character across repeating cycles, so one character on its own cannot pin down an absolute year. When that happens the tool picks the most recent year that has already occurred, marks the result medium confidence, and lists the other years the same code could mean.
Where to find the Monogram serial number
The serial number is printed on the rating label, usually alongside the model number — never on the front of the appliance where you would look first. Where that label sits depends on what the appliance is:
| Monogram appliance | Where the rating label usually is |
|---|---|
| Refrigerator | Inside the fresh-food compartment on a side wall; near the upper shelf; behind crisper drawers; or on the exterior side/rear panel. |
| Dishwasher | On the left, right or top edge of the door; on the tub frame; sometimes on the kick plate. |
| Range / Oven | On the frame behind the oven door; behind the lower drawer; beneath the cooktop; or on the rear panel. |
| Microwave | Inside the door frame or cavity wall; on the vent grille housing for over-the-range models. |
Photograph the label rather than copying it by hand. The character that carries the year is one of about a dozen on the line, and a 0 read as an O costs you the lookup. Our label location guide has the same guidance for every brand.
Common questions about Monogram appliance age
How old is my Monogram refrigerator?
Read the serial number off the rating label and type it into the tool at the top of this page. It returns the month and year the unit left the factory, which is not the day it was sold: an appliance commonly spends six to twelve months between the production line and a kitchen, and clearance stock far longer.
Does a Monogram serial number contain the manufacture date?
Yes, but encoded rather than printed. Monogram carries the date in one format, where one character stands for the year and another for the month. The tables above name those positions, so you can check the tool's answer by hand.
Where is the serial number on a Monogram refrigerator?
Inside the fresh-food compartment on a side wall; near the upper shelf; behind crisper drawers; or on the exterior side/rear panel. It sits on the same label as the model number. Photograph it — misreading one character is the usual reason a lookup fails.
Why does the tool show more than one possible year?
Monogram reuses year characters on a cycle, so a single character cannot separate, say, 2005 from 2025. The tool shows the most recent year that has already passed and lists the alternatives rather than hiding the doubt. If you know roughly when the appliance was bought, the candidate nearest that date is the right one.
