This premium two-stage air pressure switch is a vital safety component for high-efficiency furnaces and residential HVAC systems. As an essential air-proving sensor, it monitors the pressure generated by the draft inducer motor to ensure the venting system is clear and operating safely before allowing the ignition process to begin. Specifically engineered for dual-stage heating units, this switch features two distinct pressure thresholds to manage both low and high-fire combustion cycles. If your furnace is failing to ignite, cycling off prematurely, or displaying pressure-related error codes, this reliable replacement switch ensures your heating system maintains proper airflow and optimal performance during the colder months.
