What’s on the rating plate?

Matching North American Electrolux/WCI-produced appliances.

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.

Scope matters

and historical limits.

  • Gibson guitars, HVAC systems, early independent brands and GM-era Frigidaire are different systems.
  • A single year digit does not establish the decade; all supported decade candidates remain visible.

Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.

North American Electrolux/Frigidaire YWW

North American Frigidaire/Electrolux and matching documented WCI-family major appliances using the 10-character format.

The decade is not encoded. Product letter codes may vary by era and family; they are appliance-type clues, not model identity. Excludes Frigidaire HVAC, General Motors-era Frigidaire and non-North-American systems. Factory code is shown without an invented location.

Reading your result

Tappan 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.
