This premium 1.00" WC air pressure switch is a vital safety component designed for high-efficiency gas furnaces. As an air proving switch, it plays a critical role in the furnace ignition sequence by monitoring the draft inducer motor. It ensures that the venting system is clear and that proper airflow is established before allowing the heating cycle to begin. If your furnace is failing to ignite or shutting down prematurely due to a pressure sensor error, this replacement switch provides a reliable solution to restore safe and consistent heating. Engineered for precision and durability, this switch helps maintain the operational integrity of your HVAC system by detecting specific vacuum or pressure levels required for safe combustion.
