Reading this list
Item is the callout number printed on the exploded diagram for AC FURNACE ASSEMBLY — match it to the drawing rather than to the description, which is often abbreviated on the manufacturer's sheet. Of the 30 parts here, 26 carry a distributor number you can order against directly, and 4 are manufacturer-number only — those you'll be sourcing through the brand or a dealer.
8 rows carry a supersession or substitution note. Read those before ordering — a listed substitute is not always a like-for-like swap, and on control boards in particular it can change how the unit behaves.
