Ensure your heating system operates safely and efficiently with this replacement air pressure switch. Designed for high-efficiency gas furnaces, this air proving switch acts as a critical safety mechanism by monitoring the combustion air pressure produced by the draft inducer blower. If the venting system is obstructed or the inducer motor fails, this switch prevents the ignition sequence to protect your home from potential hazards. Calibrated to a precise -1.10" WC set point, it is an essential component for troubleshooting furnace startup issues, ignition failure, or airflow-related error codes. This high-quality HVAC part is built for durability and precision, restoring reliable performance to your residential heating unit.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
