How to Find Your Appliance Model Number

The appliance model number is the key to finding the correct replacement part. Use the manufacturer’s model/serial label — not the number printed on the old part.

Copy the model number exactly, including letters, numbers, dashes, dots, and suffixes.

Know what to look for

Model number vs. serial number vs. part number

Use this

Model Number

Identifies the appliance design and is the number we normally need to verify part compatibility.

Examples: WTW5000DW1 · GNE27JYMFS · DLEX4000W
May also appear on label

Serial Number

Identifies your individual appliance and can help determine production date or revision.

Usually labeled “Serial,” “S/N,” or “SER.”
Do not use for appliance ID

Part Number

A number printed, molded, or stamped on the old component may identify that component, not your appliance.

A stamped number is not always the orderable service part number.
Common label locations

Where to find the model number

Exact locations vary by brand and model. Look for a white, silver, or black manufacturer label containing both model and serial information.

Washer

  • Inside the lid or door opening
  • On the cabinet near the door frame
  • Rear panel or back of the control console

Dryer

  • Inside the door opening or door frame
  • Near the lint-filter area
  • Rear cabinet panel

Refrigerator / Freezer

  • Inside the fresh-food compartment
  • Left or right interior wall, ceiling, or near crispers
  • Sometimes on an exterior side or rear panel

Dishwasher

  • Top or side edge of the door
  • Along the tub opening / door frame
  • Visible after opening the dishwasher door

Range / Oven

  • Inside the oven door frame
  • Behind or beside the lower storage drawer
  • Sometimes on the back of the appliance

Microwave

  • Inside the door frame when opened
  • Interior wall near the opening
  • Back or side of some units
Best option

Take a clear photo of the entire model/serial label

Photos prevent mistakes caused by characters that look similar, such as 0 / O, 1 / I, or 5 / S.

Before sending it to us

Tips for reading the label

1

Look for the words Model, Model No., MOD, or M/N.

2

Include every suffix or revision character printed after the main model number.

3

Do not rely on a sticker placed on a replacement part, motor, control board, or packaging.

4

If the label is faded, take several photos with different lighting and angles.
