Product Details

Description

This premium 2-stage air pressure switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. Functioning as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure that flue gases are being properly exhausted before allowing the ignition process to proceed. Specifically calibrated for two-stage heating units, this switch features dual setpoints of -0.15" WC and -0.35" WC, allowing the system to verify airflow requirements for both low-fire and high-fire operations. If your heating system is experiencing ignition failure, frequent cycling, or displaying pressure switch circuit errors, this reliable replacement part ensures your furnace operates safely and efficiently.
