The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM sealing plug used on the AMVM971205DNBA modulating variable-speed gas furnace and other AMVM97-series cabinets. It closes off unused knockouts, wiring ports, and access holes to keep conditioned airflow inside the cabinet and block dust, insects, and moisture from entering sensitive control areas.

Specifications

  • Part number: A1781105
  • Type: 1-piece push-in vinyl cap
  • Material: Flexible molded vinyl
  • Brand: Goodman / Amana OEM
  • Fits: AMVM971205DNBA and compatible AMVM97 furnaces

OEM vs. Generic

This is the factory Goodman part, molded to the exact port diameter so it seats flush and stays put through thermal cycling. Generic universal caps often loosen or leak air over time; the OEM cap guarantees a correct, rattle-free fit.

Install Difficulty

Very Easy (1/5) — Press-fit by hand into the port. No tools, no wiring. A 1-minute job for any homeowner or technician.
