Once you have your appliance's model number, the next step is the part number. The part number identifies the exact component, and it is usually printed or stamped on the part itself. Finding it saves you from ordering the wrong part and paying return shipping.
This guide explains where to look and how to read the number.
- Look on the part itself — most parts have a number stamped or printed on them.
- Also check the appliance's parts diagram for your model.
- Part vs model number: the part number identifies the component.
- Photograph it before ordering.
- Verify the fit against your model number.
Where to find it
| Location | How to find it |
|---|---|
| On the part | Stamped or printed on the component |
| Parts diagram | Look up your model number online |
| Old part label | Check the label on the failed part |
| Manual | The parts list in the manual |
| Manufacturer site | Search by model number |
Most parts have the number stamped into the metal or printed on a label. A relay, a thermostat or a heating element will usually have a number on it. If it does not, look up your model number in a parts diagram, which lists every part and its number.
Reading the number
Part numbers are usually a mix of letters and digits, and they are specific. A single different character can mean a different part. Write it down exactly, including dashes and letters, and photograph the label so you have a record.
- Copy it exactly — every character matters.
- Note the manufacturer — the same part may have different numbers by brand.
- Check for a revision letter at the end.
- Photograph the label before the part is discarded.
- Compare with the diagram to confirm.
- Keep the number for future repairs.
Ordering the right part
- Get your model number from the appliance's rating plate.
- Find the part number on the part or in the diagram.
- Search both numbers together to confirm the fit.
- Check the seller's fit list for your model.
- Prefer OEM for complex parts, aftermarket for simple ones.
- Check the return policy before ordering.
Find your appliance part number on the part itself, or in the parts diagram for your model. Copy it exactly, photograph the label, and search it together with your model number to confirm the fit before ordering.
