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.

Who built your Kenmore appliance?

The first three digits of the model number, the part before the period, name the company that built the unit. The serial number then follows that company’s date code.

Where to find the serial number

The tag carries the model number and the serial number. The model number looks like 110.12345678: the three digits before the period name the builder.

ApplianceWhere the serial tag is
RefrigeratorInside the fresh-food compartment on a side wall or the ceiling, behind the crisper, or behind the kick plate
WasherUnder the lid, around the door frame, or on the rear panel
DryerAt the door opening, or on the rear panel
DishwasherOn the rim of the tub or the inside edge of the door
RangeAround the oven door frame, or inside the drawer compartment
MicrowaveInside the cavity near the door frame. Over-the-range models: behind the vent grille

If the serial number does not decode

  • A model number starting 630 is a dishwasher built by Bosch. Look for a separate FD number on the tag and use the Bosch decoder.
  • Kenmore microwaves, and Kenmore appliances from builders not listed here, are not covered.
  • Use the printed manufacture date when the tag has one. Frigidaire-built Kenmore tags often do.
