Product Details

Description

This premium 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 allowing the furnace to ignite. If your heating system is experiencing ignition failure, intermittent cycling, or pressure switch lockout errors, this precision-calibrated component is the ideal replacement. It features dual set points of 0.35" WC and 0.50" WC to maintain strict safety standards and optimal appliance performance. Built for durability and reliability, this switch protects your home by preventing the burner from firing under unsafe venting conditions.
