This premium Goodman pressure switch is a critical safety component designed for residential gas furnaces. As an air proving switch, its primary function is to monitor the negative pressure generated by the furnace inducer motor, ensuring that the combustion blower is operating at the correct speed and that the venting system is clear of obstructions. By verifying proper airflow, this switch allows the ignition sequence to proceed safely, protecting your HVAC system from hazardous operating conditions. If your furnace is short-cycling, failing to ignite, or triggering a pressure switch lockout error, this genuine replacement part restores consistent heating performance and system reliability. It features a factory-calibrated set point of -0.70" WC for precise sensitivity and long-lasting durability.
