Serial number decoder for Thermador range

Serial no.

Type the serial from the data plate, not the model number. Nothing is sent anywhere; the tables are in this page.

Format example: FD930356731

Thermador range serial numbers in the era not stated format encode the year as digits 1-2 after FD + 20, keep last two digits: 93 + 20 = 113 -> 13 -> 2013 (i.e. year = (YY + 20) mod 100; 80-99 => 2000-2019, 00-19 => 2020-2039, 60-79 => 1980-1999) and the week as digits 3-4 per building-center (03 = week 3); possibly month - unverified (source: building-center.org).
Example: serial FD930356731 decodes to week 3 of 1993.

Trap: Offset arithmetic is easy to get wrong; wraps every 100 years. Week-vs-month unresolved. Same rule for Thermador and Gaggenau.

Listed under Bosch (appliances) in the source; Thermador 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.
