How to decode a Whirlpool serial number

Most Whirlpool-family appliance serial numbers use a year code plus a production week. Nine-character serials commonly use character 2 for year and characters 3-4 for week, while ten-character serials commonly shift that year code to character 3 and the week digits to characters 4-5.

What the model number can tell you

The model number helps separate product families, confirm the era, and support the final decade choice when the Whirlpool year code repeats on a 30-year cycle. It is also useful when the serial label is incomplete or damaged.

Common Whirlpool serial number formats

9-character Whirlpool serial ~ Estimated decade. Whirlpool year codes repeat.
Year code in character 2; week digits in characters 3-4

The year code maps the likely year window and the next two digits point to the production week.

10-character Whirlpool serial ~ Estimated decade. Whirlpool year codes repeat.
Year code in character 3; week digits in characters 4-5

The serial length changes where Whirlpool stores the year code.

Whirlpool-family brands ~ Estimated until the exact family and era are clear.
Same core year/week logic across many related brands

KitchenAid, Roper, and some Kenmore OEM paths often follow similar Whirlpool-family logic.

Cycle warning
...B25...

A Whirlpool year code such as B can map to more than one decade cycle, which is why the result may still be estimated until model era or install context confirms the right decade.

FAQ

How old is my Whirlpool appliance? expand_more

Use the full serial number from the rating label. Whirlpool usually stores a year code and production week in the serial rather than the model number.

Can a Whirlpool model number tell me the age? expand_more

Not reliably by itself. The model number is more useful for identifying the family and confirming the era when year codes repeat.

Why does Whirlpool show an estimated decade? expand_more

Whirlpool year codes repeat across long cycles, so condition, product era, and model family may still be needed to confirm the right decade.

Where is the Whirlpool serial number label located? expand_more

It depends on product type. Refrigerators usually place it inside the cabinet, laundry products place it around the opening, and dishwashers or ranges place it on the frame.

Can this be used for insurance claims? expand_more

Yes. Just document whether the result is a direct supported decode or an estimated decade based on the repeated Whirlpool cycle.
