Product Details

Description

This premium 2-stage air pressure switch is a vital safety component for high-efficiency gas furnaces and HVAC systems. Designed to function as an air proving switch, it monitors the draft created by the inducer motor to ensure combustion gases are safely vented before the heating cycle begins. This dual-stage pressure switch features precise set points of 0.30" WC and 0.75" WC, allowing it to accurately sense pressure levels for both low-fire and high-fire operations. By preventing the furnace from firing if a venting obstruction or motor failure is detected, this switch protects your heating equipment and ensures safe home operation. It is an ideal replacement part for maintaining the reliability and energy efficiency of modern multi-stage heating systems.
