Description
The Amana-Goodman 0130F00646 Pressure Switch is a furnace monitoring component used to verify airflow, and vent conditions in HVAC systems. Calibrated at -0.10″ WC the switch responds to pressure changes within the combustion or venting circuit to support safe equipment startup, and burner operation. It is commonly installed in gas furnace assemblies where pressure sensing is required for ignition sequencing, and airflow verification during heating cycles. Within the unit the switch operates as a safety control system that supports vent monitoring combustion management, and coordinated furnace performance.
