This premium air pressure switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. Specifically engineered for Trane and American Standard units, this air proving switch monitors the draft inducer motor to ensure proper airflow and venting before the ignition sequence begins. A failing pressure switch can cause furnace startup issues or intermittent shut-offs; replacing it with this precisely calibrated 1.65" WC switch ensures your heating system operates safely and efficiently. It acts as a safeguard, preventing the burner from lighting if it detects inadequate vacuum pressure or a blockage in the flue, protecting your home from the buildup of combustion gases.
