Before you buy

Read the existing part label.Look for WE03X31620 or a manufacturer-backed identifier shown here.

Frequently asked questions

Can I search by appliance model instead?

Yes. The model-number lookup on the catalog homepage uses only documented mappings that have been added to our database.

Is this fit list complete?

No. We publish documented mappings as we verify them. A missing model means “not indexed yet,” not “incompatible.”

Can I trust an aftermarket fit list?

Treat it as a shopping claim rather than our compatibility evidence unless an OEM or manufacturer source supports the same mapping.
