OEM Goodman / Amana 1-Piece Vinyl Cap — A1781105

The Goodman A1781105 is a genuine OEM 1-piece vinyl cap used on the AMEC960603BNBB furnace and many compatible Goodman/Amana models. These caps insulate and protect unused terminals, wire ends, and connection points from moisture, dust, and accidental contact. Though inexpensive, using the correct factory cap keeps your furnace wiring tidy, safe, and to code.

Specifications

Part Type: Vinyl protective cap / cover (1-piece)
Material: Molded vinyl, non-conductive
Use: Insulates and protects terminals or wire ends
Fits: Amana/Goodman AMEC960603BNBB and compatible furnaces
OEM Part Number: A1781105
Brand: Goodman (Amana equipment)

OEM vs. Generic

The OEM A1781105 is sized to grip factory terminals and wire gauges snugly so it stays put through heating and vibration cycles. Generic caps may be loose or brittle and can slip off, leaving connections exposed. At this price point, the genuine part is an easy call.

Installation Difficulty

Very Easy (1/5). Push-on installation — simply slide the cap over the terminal or wire end. No tools required. As always, disconnect power before working inside the furnace cabinet.
