How old is my Monogram range?

Serial number age decoder for Monogram ranges, ovens and cooktops: 1 format era, the decode rule in plain English, transcribed tables, and the official lookup.

• Monogram range serial numbers in the 1977 to present format encode the year as letter 2 via 12-year cycle (table below) and the letter 1 = month (table below) (source: products.geappliances.com).
• Example: serial LR821547C decodes to 2020 or 2008 or 1996 or 1984 (June).
• The 1977 to present format is ambiguous: Official GE Appliances page. Year letter repeats every 12 years, so GA = April 2001 or April 2013 (GE's own example); GE says to use the print date on the owner's manual (e.g. 02-20) to pick the cycle, or contact them with model + serial. Building-center's Hotpoint page text says '1st = year, 2nd = month' - that is backwards (its GE page, GE's page and the VZ902110G plate stamped NOVEMBER 1988 all say month first). Pre-1977 codes (E=1969/1948, N=1972/1956, two-letter codes AY..DB for 1961-68, B/C/J/K for 1945-53) are in the official table but rarely matter. Worked examples: VZ902110G = Nov 1988 (building-center plate photo), ZV700153M = Dec 1975/1987/1999, LR821547C = Jun 2020, RL059433C = Aug 2018, ZR525322 = Dec 1996, LV227019H = Jun 1999 (Hotpoint), RD166115R = Aug 2002 (Hotpoint) (appliancedates).
• Monogram's official lookup at monogram.com returns warranty / registration lookup.

trailing letter is not documented (GE says serials 'begin with two letters, followed by six numbers, with a letter at the end'); older plates omit it

Example: serial LR821547C decodes to 2020 or 2008 or 1996 or 1984 (June).

Listed under GE Appliances in the source; Monogram is named in that format's family and the corporate link is an estimate, not a checked fact.

Where the data plate is on a range

Open the oven door or the storage drawer and look on the frame; slide-in ranges often carry it under the cooktop lip.

General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.

For scale only: the InterNACHI Standard Estimated Life Expectancy Chart for Homes lists Electric Range / Gas Range at 13 to 15 / 15 to 17 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.

What we could not confirm

• Monogram is treated as sharing GE Appliances's format because the source lists it in that family; the corporate relationship itself is an estimate.
• GE Appliances luxury brand; GEA serial format (GE's support library even carries Monogram articles). monogram.com/support curl 200 (hub only). No building-center page.
