Ensure your heating system operates safely and efficiently with this high-quality air pressure switch. Designed for Lennox, Armstrong, and Concord gas furnaces, this air proving switch is a critical safety component that monitors the negative pressure created by the draft inducer motor. By verifying proper airflow and venting, it prevents the furnace from igniting under unsafe conditions, protecting your home from potential exhaust blockages or motor failures. This replacement part is ideal for HVAC repairs where the furnace is failing to ignite or throwing pressure switch circuit codes. Built for durability and precise calibration, it helps restore reliable performance to your residential heating unit.
