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