How old is my Whirlpool appliance?

Reading a Whirlpool serial number

Whirlpool serials start with a plant code, then a year character and a two-digit week. C60842986 means week 8 of 2016, built in Clyde, Ohio.

Year codes repeat. A digit can mean the 1970s, 1980s or 2010s, and the 1990s letters came back in 2020. The checker lists each fit.

About Whirlpool

Whirlpool is based in Benton Harbor, Michigan.
Its US plants include Clyde, Ohio (washers), Findlay, Ohio (dishwashers), Tulsa, Oklahoma (ranges), Amana, Iowa (refrigeration) and Ottawa, Ohio (compact and chest freezers).
Whirlpool bought Maytag on March 31, 2006, in a deal worth about $2.6 billion with debt. That added Maytag, Jenn-Air and Amana to its brands.

Used 1970s to today. Example: C60842986

Worked example: C60842986 fits Week 8 of 1976 (around February) or Week 8 of 1986 (around February) or Week 8 of 2016 (around February). The page above explains how to tell which.

Where the serial is on a Whirlpool

On a refrigerator, look on the inside wall of the fresh food section near the top. On a dishwasher, check the edge of the inner door or the side of the tub opening. On a range, open the oven door and look on the frame, or behind the storage drawer. On a washer or dryer, check under the lid, around the door opening, or on the back of the console.
