This high-performance two-stage air pressure switch is a vital safety component designed for Goodman and Amana gas furnaces. As an essential air-proving switch, it monitors the pressure generated by the inducer motor to ensure the heating system has proper venting and airflow before ignition. This dual-stage sensor is critical for preventing the furnace from operating under unsafe conditions, such as a blocked flue or a failing vent motor. Engineered for precision and reliability, this switch features specific calibrated trip points to maintain the efficiency and safety of high-efficiency 2-stage heating units. It is an ideal replacement part for HVAC systems experiencing ignition failures or pressure-related error codes.
