Whirlpool serial number lookup: how old is the appliance?

The serial number is on a tag inside the appliance: on the wall of the fresh-food compartment of a refrigerator, or on the rim of the door opening of a washer, dryer or dishwasher. In a Whirlpool serial the second character is the year and the two digits after it are the week.

Look for “Serial”, “Serial No.” or “S/N” on the rating plate. It is not the model number. What you type stays in your browser.

Where to find the serial number

Whirlpool puts the model and serial tag where it can be read without moving the appliance.

ApplianceWhere the serial tag is
RefrigeratorInside the fresh-food compartment: on the left wall of top-freezer, bottom-freezer and French-door models, on the right wall of side-by-side models
FreezerUpright: right-hand side near the top. Chest: left interior side wall
WasherFront-load: on the rim of the door opening. Top-load: under the lid, on the rim of the tub
DryerOn the rim of the door opening
DishwasherOn the left side of the tub frame, visible with the door open

If the serial number does not decode

  • A digit as the year code means 2010 to 2019 in this layout. Whirlpool also used digits in the 1970s and 1980s, in a layout the decoder does not cover.
  • A serial with two letters before the year code comes from a unit another company built for Whirlpool, such as some microwaves. The decoder does not read those.
  • The print date in the owner’s manual or on the installation sheet shows which decade a repeating code belongs to.

Questions and answers

Which characters in a Whirlpool serial number show the date?

The first letter is the plant. The second character is the year, as a letter or a digit. The two digits after it are the week. This applies to units built since 1990.

The decoder shows more than one possible year. Which one is right?

Part of the Whirlpool date code repeats, so the serial alone fits more than one year. A manufacture date printed on the rating plate, the print date of the owner’s manual or the installation record settles it. For equipment that is still running, the more recent year is usually the right one.

Is the letter R 2004 or 2005?

R is 2004. Several websites print the Whirlpool year table one year late for 1999 to 2009. Recall notices settle it: Whirlpool ovens with serials from R15 to R25 were sold from April to July 2004, and dishwashers with W39 to W52 followed by Y01 onward were built in 2008 and 2009.
