This premium 2-stage air pressure switch is a critical safety component designed for high-efficiency Goodman and Amana gas furnaces. Functioning as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure exhaust gases are being properly vented before allowing the furnace to ignite. This dual-stage switch features two precise set points— -0.30" WC and -0.75" WC—making it essential for furnaces that operate with variable heating speeds. If your heating system is experiencing ignition failure, intermittent cycling, or specific pressure switch lockout codes, this replacement part is necessary to restore safe and reliable operation. Built for long-term durability, it helps maintain the integrity of your HVAC system's combustion safety circuit.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
