The Goodman 0161A00034 breaker insert is a genuine OEM electrical component engineered for the ARUF032-00A-1B air handler and compatible Goodman/Amana platforms. This small but critical insert seats into the air handler's electric heat circuit, providing the correct mechanical and electrical interface for the breaker assembly. Using the factory-specified part ensures proper contact, safe current handling, and long-term reliability inside the cabinet.
This is the genuine Goodman OEM insert, machined to factory dimensions for a guaranteed fit. Generic substitutes are rarely available for this part and risk improper seating, which can compromise the electric heat circuit. For an electrical component this small and inexpensive, the OEM part is always the right choice.
Easy — replacement takes only minutes for a qualified technician once power is disconnected. Always shut off and lock out power at the breaker before servicing. If you are not comfortable working inside an air handler's electrical compartment, contact a licensed HVAC professional.
