Source1 2440873000 Pressure Switch 0.85 Inches

Product Description

The Source1 2440873000 is a pressure switch rated at 0.85 inches water column, designed for use in HVAC systems where reliable pressure sensing and circuit control are essential. Pressure switches are critical safety and control components found in furnaces, air handlers, heat pumps, and other forced-air heating and cooling equipment. They monitor static pressure levels within the system and open or close an electrical circuit based on whether pressure has risen above or dropped below a set threshold. When the system is operating correctly, the pressure switch confirms proper airflow or inducer motor function before allowing the control board to proceed through the ignition or operating sequence. This helps prevent unsafe operation and protects heat exchangers, combustion components, and other downstream parts from damage caused by insufficient draft or blocked venting. The Source1 2440873000 is set to a 0.85 inches water column trip point, making it suitable for specific furnace and air handler applications that require this precise pressure threshold. HVAC technicians rely on accurately rated pressure switches during routine maintenance, system diagnostics, and component replacement. Using the correct trip point is essential for safe and reliable system operation. Source1 is a trusted supplier of OEM-compatible HVAC replacement parts, and this pressure switch is built to meet the performance requirements of the systems it serves. Proper installation ensures the switch responds accurately to pressure changes, maintaining the safety logic of the control sequence. This part is a direct replacement option for technicians servicing residential and light commercial HVAC equipment that requires a 0.85 inches water column pressure switch.
