The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM accessory for the Amana/Goodman AMVM970603BNBA furnace and compatible AMVM97-series models. This molded vinyl cap plugs an unused drain, pressure-tap, or conversion port to keep the cabinet sealed and prevent air leakage, moisture intrusion, and debris entry. Though inexpensive, a missing or brittle cap can cause pressure-switch faults or condensate-side air leaks, so replacing a cracked cap restores proper furnace operation.

Specifications

Type: One-piece molded vinyl cap / port plug
Material: Flexible vinyl for a snug press-fit seal
OEM part number: A1781105
Compatibility: AMVM970603BNBA and select AMVM97 furnaces
Quantity: 1-piece

OEM vs. Generic

The OEM A1781105 is sized to the exact port diameters used on the AMVM97 platform, giving a leak-free press fit. Generic rubber or vinyl caps from a hardware store may seal temporarily but often loosen with heat cycling. For a low-cost part that affects furnace pressure balance, OEM is worth it.

Installation Difficulty: Easy

No tools required — remove the old cap and press the replacement firmly onto the port until fully seated. Verify a snug fit and confirm the furnace runs without pressure-switch errors. Under 5 minutes.
