Description
Amana-Goodman 0130F00957 Pressure Switch is an airflow safety control component used to monitor differential pressure created by the inducer, or blower and verify proper venting conditions before system operation continues. It change the electrical contact state when the measured pressure reaches a calibrated threshold, ensuring correct air flow through combustion and exhaust pathways. In HVAC systems it is used in furnace assemblies where it confirms adequate draught within the heat exchanger and flue circuit before ignition. It helps maintain safe combustion conditions, supports startup sequencing, and prevents operation when airflow is restricted or venting performance is outside expected limits.
