The ICP 2-Stage Air Pressure Switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. This air proving switch monitors the pressure generated by the inducer motor, ensuring that flue gases are properly vented before allowing the heating system to ignite. Specifically engineered for two-stage heating units, it accurately detects the specific draft requirements for both low and high heat cycles. If your furnace is failing to start or displaying a pressure switch lockout code, this replacement part is essential for restoring safe and reliable operation. Built for precision, it helps maintain peak efficiency and protects your home by preventing the operation of the burner under unsafe venting conditions.
