HEATSTAR 60147 Pressure Switch

The Heatstar 60147 Pressure Switch is a safety control component that monitors air pressure within the venting system before permitting heating operation. An internal diaphragm responds to pressure changes, opening or closing electrical contacts according to established pressure conditions. Mounted along the inducer or vent tubing, it communicates with the inducer assembly, control board, and ignition circuit to verify proper airflow within HVAC systems before burner operation begins. Verified pressure conditions maintain coordinated startup sequencing while limiting operation under improper venting conditions. Its operations support proper pressure monitoring, coordinated safety control, ignition sequencing, and proper system performance.
