Ensure your heating system operates safely and efficiently with this high-quality 0.65" WC Air Pressure Switch. Designed as a critical safety component for high-efficiency gas furnaces and residential HVAC units, this air proving switch monitors the pressure differential created by the draft inducer motor. It acts as a sensor to confirm that exhaust gases are being properly vented before allowing the furnace to proceed with the ignition cycle. If your furnace is failing to ignite or throwing a pressure switch error code, this precisely calibrated replacement part is essential for restoring reliable heating performance and ensuring a safe environment in your home. Built for durability and accuracy, it prevents the combustion process from starting unless optimal airflow conditions are met.
