This premium Combustion Blower Restrictor is a critical component for optimizing the performance of your furnace's heating cycle. Specifically designed to work in tandem with the inducer motor or draft venter assembly, this restrictor plate regulates the volume of air flowing through the combustion chamber. By maintaining precise static pressure, it ensures the pressure switch activates correctly and the air-to-fuel ratio remains at peak efficiency. If your heating system is experiencing ignition issues or venting errors, a faulty or missing blower restrictor may be the cause. Crafted from durable, heat-resistant materials, this part is essential for ensuring safe exhaust gas expulsion and consistent heating performance in residential and commercial HVAC units.
