Amana-Goodman 0130F00155 0.81" SPST WC Pressure Switch

The Amana-Goodman 0130F00155 0.81" SPST WC Pressure Switch is a control component designed to monitor pressure conditions within compatible heating and cooling systems. It uses pressure changes to open or close an electrical circuit, allowing connected controls to respond when the required pressure level is reached. The switch connects to tubing, wiring, and control assemblies inside the unit for pressure sensing and electrical switching. In HVAC systems, it regulates safety and operating sequences by communicating pressure status to connected parts during system operation and control cycles.
