Description
The Amana-Goodman 0130F00438S Pressure Switch is an airflow safety control used to regulate inducer and venting operation within high-efficiency furnaces. It operates as a control and safety circuit by monitoring pressure created by the inducer motor and allowing system ignition only when proper draught conditions are verified. When the pressure level reaches the calibrated setpoint, the switch closes to permit burner operation, and it opens again if airflow becomes restricted. Commonly installed in compatible furnace models, it maintains stable combustion performance and supports controlled system shutdown under unsafe venting conditions.
