This high-performance air pressure switch with an integrated mounting bracket is a critical safety component designed for modern HVAC systems and gas furnaces. Functioning as an air proving switch, it is calibrated to a precise 0.52" WC (Water Column) set point to monitor the pressure differential generated by the draft inducer motor. This sensor ensures that the combustion blower is operating correctly and that exhaust gases are being properly vented before the ignition sequence is allowed to begin. If your heating system is experiencing ignition failure or cycling issues, replacing a faulty air pressure switch is essential for restoring safe and efficient operation. Durable and reliable, this component is an ideal replacement for maintaining the integrity of your furnace's safety circuit.
