Kenmore serial number lookup

Kenmore serial numbers do not follow one rule. The date code depends on the product, so choose the equipment first.

Decode a Kenmore serial number

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.

Kenmore water heaters

The serial number is on the model and serial plate on the tank jacket. Kenmore water heaters with a model number starting 153 were built by State: since 2008 the serial starts with the year and the week, and before that with a letter for the month.

2 formats on record: year and week, first four digits (built since 2008); month letter, then two-digit year (built until 2007).

Kenmore appliances

Kenmore appliances were built for Sears by other manufacturers, and the serial number follows the builder’s code. The first three digits of the model number show who the builder was. Choose them below, then type the serial.

About Kenmore

Kenmore is a store brand created by Sears and owned by Transformco since 2019. Sears never built the products itself. Each Kenmore product was made by another manufacturer, and the serial number follows that manufacturer’s format.

Related brands: State, A. O. Smith, Reliance, Whirlpool, Frigidaire, GE, LG.
