Whirlpool Date Codes

The breakdown for Whirlpool Serial Numbers is:

1st Alpha Character = Manufacturing Division Code.
2nd Alpha Character = Year Manufactured (See Tables).
1st and 2nd Digit = Week of Year Manufactured.
3rd though 7th Digit = Order of Manufacturing that Week.

For products "not built by Whirlpool", an additional alpha is used after the first alpha to indicate the source. All other alpha and numeric designations remain the same.

Whirlpool Insurance Claims - Hidden Date Codes

For insurance claims, forensics engineers must to able to determine when an appliance was manufactured. The manufacturer's paper or metal foil tag is often destroyed or unreadable after a fire.

Whirlpool has hidden permanent date codes stamped into the metal of their appliances. Except for the shorten length, the hidden date code is the same as on the paper or foil tag. The problem is finding where the date code is stamped into the metal.
