This premium two-stage air pressure switch is a vital safety component designed for high-efficiency Goodman and Amana gas furnaces. As an essential air proving switch, it monitors the pressure generated by the draft inducer motor to ensure the venting system is clear and functioning correctly before allowing the heating cycle to begin. This dual-stage switch is engineered to handle the varying pressures of a multi-stage furnace, featuring precise setpoints of -0.50" WC and -1.10" WC. If your furnace is failing to ignite, cutting out early, or showing a pressure switch error code, this reliable replacement part restores proper communication between the combustion blower and the control board. Built for durability and precision, it helps maintain optimal HVAC performance and home safety.
