Ensure your heating system operates safely and efficiently with this high-quality furnace air pressure switch. Designed as a critical air proving component, this switch monitors the negative pressure created by the inducer motor. It is engineered to open at -1.51" WC (Water Column), acting as a safety cutoff that prevents gas ignition if proper venting or airflow is not detected. This replacement pressure sensor is essential for troubleshooting heating cycles where the furnace fails to stay lit or won't start due to venting issues. Ideal for professional HVAC repairs and routine maintenance, this component helps maintain the integrity of your gas furnace's combustion process.
