This Goodman Air Pressure Switch is a vital safety component for residential gas furnaces and HVAC systems. Calibrated to a precise -0.47" WC (Water Column) set point, this air-proving switch monitors the vacuum pressure created by the draft inducer motor to ensure proper venting of combustion gases. If the exhaust system is obstructed or the inducer fan fails to reach the necessary pressure, this switch prevents the furnace from igniting, protecting the system from unsafe operation and potential hazards. This high-quality replacement part is essential for resolving common furnace startup failures, ignition lockouts, and pressure-related error codes, ensuring your heating system operates efficiently and safely throughout the winter.
