This updated HVAC air pressure switch is a critical safety component designed for high-efficiency furnaces and air handling units. Functioning as an air proving switch, it monitors the draft inducer motor to ensure that proper airflow is established and exhaust gases are being safely vented before the ignition sequence begins. Rated at a 0.65" WC (Water Column) set point, this pressure sensor helps prevent hazardous conditions by disabling the heating cycle if venting issues are detected. If your furnace is failing to ignite or displaying a pressure switch lockout error, this high-quality replacement part restores reliable performance and ensures your heating system operates at peak safety and efficiency.
