Description
The Amana-Goodman 0130F00441S Air Pressure Switch is a differential sensor that detects airflow or vacuum levels created by the inducer motor in heating equipment. It changes the electrical state when the required pressure condition is reached, allowing the control board to proceed with the ignition sequence. In HVAC systems, it is used in furnace assemblies where venting and combustion airflow must be verified before burner operation begins. The switch is typically connected to sensing tubes that monitor pressure changes in the flue and inducer housing, supporting controlled startup behaviour across heating cycles in gas-fired equipment.
