How Amana serial numbers encode the date
Amana does not print the manufacture date in plain text on most units — it is encoded into the serial number. The decoder recognises 4 formats for this brand:
Format 1: Repeating year code with production week
The 2nd character is the year code, followed by 2 digits at the 3rd character giving the production week of that year.
Applies to serial numbers 4–9 characters long.

Worked examples
Each example below is decoded by the same engine that powers the tool on this page, so what you see here is exactly what you would get by typing it in.
This tool returns March 2004 · production week 10 · high confidence
Shows a year letter that is never reused, so the year comes back unambiguous.
Why the year can be ambiguous
Amana 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 Amana serial number
The serial number is printed on the rating label, usually alongside the model number. Depending on the appliance it may be inside the door frame, under the lid, behind a drawer or on the rear panel. Our label location guide shows where to look for each appliance type.
