DFLD40131 parts reference: Linked manufacturer part numbers open matching product listings. Other part numbers remain visible for identification, including serial-dependent sail switches, motor 30720, and burner orifice 30887 pending application verification. The diagram calls 30887 an LP orifice, but the current product listing describes natural gas; do not substitute gas components based on part number alone. Confirm furnace model, original component, fuel configuration and serial number before ordering. LP gas service must be performed by a qualified technician.
