How to find the age of your Kenmore wall oven
less than a minute readJan 12Lyle Weischwill
Whether you’re planning a repair or a complete kitchen remodel, knowing the age of your Kenmore wall oven can make the decision easier. Built-in wall ovens are replaced less frequently than freestanding appliances, so age can affect everything from parts availability to performance expectations. If you’re troubleshooting a wall oven problem or considering an upgrade, knowing when the oven was built gives you useful information before you move forward.
Kenmore wall ovens don’t use one universal date code. Instead, you’ll need to decode the serial number on the model label. How you do that depends on the first three digits of the model number. Find that prefix first, then decode the serial number using the format tied to it.
Where to find the model and serial number on your wall oven
Start by locating the model and serial number label on your Kenmore wall oven. On most models, both numbers appear together on the same label.
Common locations include:
Along the oven frame behind the door
On the side trim when the door is open
On the lower edge of the control panel area
The model number usually starts with three digits, followed by a period and additional numbers. Those first three digits determine which serial number format you’ll use to find the production date.
If your wall oven’s model number starts with 363 or 364
Kenmore wall ovens with model numbers starting with 363 or 364 use a serial number format where the production date is encoded at the start of the serial number using letters.
Serial number format for 363 and 364 wall ovens
The serial number typically begins with two letters:
First letter = month
Second letter = year
This format provides the **month and year** the wall oven was built.
Year and month code reference (1990 and newer)
| Letter | Month (first letter) | Possible years (second letter) |
|---|---|---|
| A | January | 2001, 2013, 2025 |
| D | February | 1990, 2002, 2014, 2026 |
| F | March | 1991, 2003, 2015 |
| G | April | 1992, 2004, 2016 |
| H | May | 1993, 2005, 2017 |
| L | June | 1994, 2006, 2018 |
| M | July | 1995, 2007, 2019 |
| R | August | 1996, 2008, 2020 |
| S | September | 1997, 2009, 2021 |
| T | October | 1998, 2010, 2022 |
| V | November | 1999, 2011, 2023 |
| Z | December | 2000, 2012, 2024 |
Choosing the correct year
Because letter codes repeat over time, use the wall oven’s controls, styling, and features to determine which year makes sense.
For wall ovens beginning with 664 or 665
Kenmore wall ovens with model numbers starting with 664 or 665 use a serial number format where the production date is encoded near the beginning of the serial number.
Start by looking at the first four or five characters.
Serial number format for Kenmore 664 and 665
LLYWWxxxxx or LYWWxxxxx
First one or two letters = production location
Next character (letter or number) = year
Next two digits = week of production
The year is shown as a single character, and the pattern repeats every 30 years.
Year code reference table
| Codes 0–9 | Years | Codes X–J | Years | Codes K–Y | Years |
|---|---|---|---|---|---|
| 0 | 1980 / 2010 / 2040 | X | 1990 / 2020 / 2050 | K | 2000 / 2030 / 2060 |
| 1 | 1981 / 2011 / 2041 | A | 1991 / 2021 / 2051 | L | 2001 / 2031 / 2061 |
| 2 | 1982 / 2012 / 2042 | B | 1992 / 2022 / 2052 | M | 2002 / 2032 / 2062 |
| 3 | 1983 / 2013 / 2043 | C | 1993 / 2023 / 2053 | N | 2003 / 2033 / 2063 |
| 4 | 1984 / 2014 / 2044 | D | 1994 / 2024 / 2054 | P | 2004 / 2034 / 2064 |
| 5 | 1985 / 2015 / 2045 | E | 1995 / 2025 / 2055 | R | 2005 / 2035 / 2065 |
| 6 | 1986 / 2016 / 2046 | F | 1996 / 2026 / 2056 | T | 2006 / 2036 / 2066 |
| 7 | 1987 / 2017 / 2047 | G | 1997 / 2027 / 2057 | U | 2007 / 2037 / 2067 |
| 8 | 1988 / 2018 / 2048 | H | 1998 / 2028 / 2058 | W | 2008 / 2038 / 2068 |
| 9 | 1989 / 2019 / 2049 | J | 1999 / 2029 / 2059 | Y | 2009 / 2039 / 2069 |
Examples:
RA01xxxx = was made in the first week of either 1991 or 2021.
FM644xxxx = was made in the 44th week of either 1986 or 2016.
Choosing the correct year
Because the year code repeats every 30 years, use the wall oven’s design and control style to determine the correct decade.
If the model number starts with 790
Kenmore wall ovens with model numbers starting with 790 typically use a serial number format where the production date appears near the beginning of the serial number.
Common serial number format
YWWxxxxx
First digit = last digit of the year
Next two digits = week of production
Use the oven’s controls, features, and styling to determine the correct decade.
Confirm the age before repairing or remodeling
After decoding the production date, make sure it aligns with your repair or renovation plans.
Helpful cross-checks include:
Whether the age fits the wall oven’s control layout and features
Whether parts availability matches the estimated timeframe
Whether the oven’s styling aligns with the decoded production date
If something doesn’t add up, revisit the serial number format before moving forward with repairs or a remodel.
