Reading this list

Item is the callout number printed on the exploded diagram for REPLACEMENT — match it to the drawing rather than to the description, which is often abbreviated on the manufacturer's sheet. Of the 20 parts here, 5 carry a distributor number you can order against directly, and 15 are manufacturer-number only — those you'll be sourcing through the brand or a dealer.

1 row carries 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.
