The Goodman A1781105 1-Piece Vinyl Caps are a genuine OEM component for the AMVM971005CNAA gas furnace and compatible Goodman/Amana equipment. These flexible vinyl caps seal off unused ports, tube stubs, or terminal ends to keep out dust, moisture, and debris, and to block air leaks that could affect pressure-switch readings or combustion draft. Small but functional, a missing cap can lead to false pressure signals and nuisance faults.
