Check a documented system

What’s on the rating plate?

Confirmed Maytag-built household-appliance variant only.

Spaces and dashes are accepted. Check O/0 and I/1, and keep any leading zeros.

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.

  • Imperial can also be a Whirlpool laundry series or an unrelated commercial cooking brand. Confirm the actual maker first.
  • No universal independent-era or current-licensed decoder was verified for this badge. Serial matching shape alone is insufficient.

Confirmed Maytag-built legacy appliance only: trailing year/month

Matching legacy Maytag household appliances and documented Maytag-built variants.

Two trailing letters encode year then month. The 24-year cycle requires model/era context; legacy serials continued after Whirlpool acquired Maytag. Do not truncate at 2006 or apply to earlier independent brands just because ownership later changed. This brand needs explicit numbering-family selection because independent historical numbering and later licensees differ.

Confirm Maytag-built appliance using model-specific documentation. Brand ownership alone does not establish the date system.

Reading your result

Imperial lookup questions

Why does the year code match more than one year?

Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.

Does the serial identify my exact model?

Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.

Can I share the result?

After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
