The Goodman 0161A00034 is a genuine OEM breaker insert engineered for the ARUF042-00A-1B air handler and compatible Goodman/Amana electric-heat models. It provides the manual-reset overcurrent protection that keeps the electric heat kit and blower circuit safe from overload and short-circuit faults. Installing the correct factory insert ensures the heat package trips at the exact rating Goodman engineered for the cabinet.
This is the genuine Goodman OEM insert, guaranteed to match the original trip rating, footprint, and terminal layout. Aftermarket inserts may differ in amperage tolerance or fitment, risking nuisance trips or improper protection. For electric-heat safety components, OEM is strongly recommended.
Easy (1/5) — A direct snap-in replacement for a licensed technician. Always disconnect power at the breaker before servicing. Professional installation recommended for any electric-heat wiring.
