Ensure your furnace operates safely and efficiently with this high-quality air pressure switch. Designed as a critical safety component for HVAC heating systems, this air-proving switch monitors the pressure differential created by the draft inducer blower. It serves as a vital safety lockout, confirming that the exhaust flue is clear and there is sufficient airflow for safe combustion before allowing the ignition sequence to proceed. If your heating system is failing to ignite or shutting down mid-cycle, a faulty pressure switch may be the cause. This replacement part features a precise 0.49" WC trip point and a Single Pole Single Throw (SPST) contact configuration to help restore reliable performance to your residential or commercial furnace.
