Menumaster commercial microwave serial number lookup
Menumaster commercial ovens are supported by ACP; household Maytag ownership charts do not establish a universal present-day decoder.

What’s on the rating plate?
Commercial microwave ovens, with historical manufacturer verified.
Scope matters
Supported formats
and historical limits.
- ACP documentation lists model, manufacturing and serial numbers separately; serial alone is not a model decoder.
- Only confirmed legacy Maytag-family trailing codes may use the opt-in legacy interpretation. Current ACP serial date fields were not verified in an original coding chart.
Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.

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
Menumaster 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.
