The Amana-Goodman 0161A00049 Vertical Drain Pan is a genuine replacement part designed for use in Amana and Goodman HVAC air handlers and furnaces. It functions by collecting condensation from the evaporator coil and channeling it safely out of the system, preventing water damage and corrosion. https://www.partshnc.com/0161a00049-amana-goodman-vertical-drain-pan
